Japan's Crypto Market 2026: A Path to Maturity and Three Key Layers

Japan is not pursuing the fastest or the freest, but is patiently building the most trustworthy crypto market.

Summary

• The critical turning point for Japan's crypto market in 2026 is not coincidental, but rather the inevitable result of over a decade of regulatory iterations. This process is characterized by a clear pattern of "crisis - framework building - institutional adoption." The collapse of Mt. Gox, the Coincheck hack, and the DMM Bitcoin incident each expanded the regulatory boundaries, culminating in the April 2026 FIEA amendment, which officially reclassified 105 approved tokens as financial instruments.
• The 2026 reform package can be described as a "comprehensive overhaul," with seven significant changes being implemented simultaneously: starting in 2028, a single tax rate of 20.315% will be applied (previously as high as 55%), new insider trading prohibitions, continuous disclosure obligations for issuers, enhanced supervision by SESC, and amendments to the Limited Partnership Act (LPS Act) allowing Japanese domestic venture capital funds to directly hold crypto assets.
• Exchange consolidation will become the most prominent structural trend in the short term. Approximately 90% of Japan's 27 licensed exchanges are currently operating at a loss, and as FIEA compliance costs continue to rise, trading volume will concentrate on a few scaled platforms, with SBI Holdings' acquisition of bitbank being the clearest signal.
• Meanwhile, Japan has established a complete infrastructure for digital yen and tokenization. Four complementary stablecoin pathways (JPYC for retail, Project Pax for B2B, JPYSC for tokenized assets, and USDC for trading), combined with the FIEA securities token framework, pave the way for institutional adoption. The spot ETF window in 2028 is expected to become the largest catalyst for capital inflow.

Part One: Market Driving Factors

How Japan Gradually Built Its Crypto Market

The development of Japan's crypto market is the result of repeated interactions between regulation and crises.

• The 2014 collapse of Mt. Gox made Japan the first major jurisdiction to seriously address custody risks, followed by the 2017 PSA amendment that made Japan the first G20 country to officially license crypto exchanges.
• The 2018 Coincheck theft of approximately $530 million directly led to the establishment of the JVCEA self-regulatory framework.
• The 2024 DMM Bitcoin hack prompted the 2025 PSA amendment, introducing asset retention orders and new levels of crypto intermediary licensing.

This path of "events triggering frameworks, frameworks driving adoption" is relatively rare globally. Most countries only respond to crises with emergency measures, while Japan has consistently turned crises into opportunities to expand regulatory boundaries and bring more activities under supervision.

Today, the FSA is directly responsible for registering exchanges (CAESP), stablecoin issuers (EPISP), and crypto intermediaries (ECISB) under the 2025 PSA amendment, with JVCEA and JSTOA operating as delegated self-regulatory organizations. This multi-layered structure, while complex, grants the FSA a high degree of market granularity control, far exceeding that of most peers.

From Mt. Gox to Maturity: A Timeline of Regulatory Evolution

The most significant feature of regulatory changes is not the number of rules, but the consistent direction: each adjustment expands the scope of permissions while retaining existing protections. The 2017 PSA registration system continued after the Coincheck incident; the stablecoin framework from 2022-2023 remained solid after the USDC controversy was approved; and the 2024 DMM incident accelerated discussions on the reclassification under FIEA.

Before 2017 can be seen as the "discovery phase," where Bitcoin was primarily traded through platforms like Mt. Gox without a specific legal status, and profits were taxed as miscellaneous income (up to 55%). Mt. Gox once accounted for over 70% of global Bitcoin trading volume, suddenly halting withdrawals in February 2014, ultimately revealing that 850,000 Bitcoins were lost.

This incident exposed the lack of segregated custody and proof of reserves, and the 2017 PSA amendment borrowed concepts from payment service regulation to position exchanges as new payment intermediaries.

The period from 2018 to 2022 is the "institutionalization phase," where JVCEA was officially established, custody rules tightened, derivatives brought under regulation, and the 2022 PSA amendment established the stablecoin EPI category. Notably, the stablecoin law was passed before issuers were ready, reserving structural time for the industry, with JPYC receiving approval in 2025 as a result.

The years 2023-2026 enter the "integration phase," with stablecoin rules coming into effect, USDC listing, JPYC registration, banking pilots, and FIEA legislation being successively implemented. The years 2027-2028 will see FIEA enforcement, the implementation of the 20.315% tax system, and the opening of the spot ETF window, forming a coherent multi-year plan.

The Two Regulatory Pillars: PSA and FIEA

Understanding Japan's regulatory framework requires grasping both laws. The PSA has defined crypto assets as payment instruments since 2017, requiring exchanges to register; since 2022, it has become the legal basis for the stablecoin EPI system.

The FIEA has long governed securities, derivatives, securities tokens (STOs), and related businesses. Before 2026, crypto primarily fell under the PSA, with the FIEA only involving derivatives and STOs.

The April 2026 FIEA amendment completely changed the landscape. It retained the PSA framework (stablecoins remain EPI, custody remains under PSA) but moved 105 spot tokens into the FIEA, introducing securities-level tools: continuous disclosure, insider trading prohibitions, market manipulation bans, and SESC supervision. Crypto is now at the intersection of both laws, gaining FIEA legitimacy and oversight while retaining PSA payment flexibility.

For participants, compliance requirements will double. Starting May 2027, licensed CAESPs must meet both PSA (custody, anti-money laundering, Travel Rule) and FIEA (insider monitoring, disclosure, market behavior) obligations. Issuers of tokens on the 105 list must publish annual reports and disclose significant events, with violations triggering SESC investigations. This marks the formal entry of Japan's crypto market into a regulated era.

Exchanges: The Market Foundation

Japan has the largest number of licensed exchanges globally (27), but trading volume is highly concentrated among bitFlyer, Coincheck, SBI VC Trade, and bitbank. Approximately 90% of platforms are operating at a loss, and the additional compliance costs (disclosure, insider monitoring, etc.) brought by FIEA will accelerate consolidation.

The future landscape is expected to form three tiers: Tier 1 will consist of 3-4 large platforms (bitFlyer, Coincheck, SBI VC Trade, and possibly the merged bitbank); Tier 2 will include 4-6 medium-sized specialized platforms; and Tier 3 will be the long tail, exiting through specialization or mergers.

Major Licensed Exchanges

bitFlyer has the longest history, the largest spot BTC/JPY trading volume, the deepest order book, and leads in institutional and high-frequency trading. Coincheck is the strongest retail brand, with an excellent app experience, a rich variety of altcoins, and a leading NFT market. SBI VC Trade focuses on institutions and has a full-stack layout, having already launched USDC, among others. On June 25, 2026, SBI announced its acquisition of bitbank (approximately $289 million), expected to be completed in October, making it the largest operator. Rakuten Wallet and GMO Coin are in the second tier, while long-tail platforms face survival pressure.

Self-Regulatory Organization JVCEA

Since 2018, JVCEA has served as the self-regulatory organization for CAESP, responsible for token selection, member supervision, and more. After the FIEA reforms, its selection function was directly managed by the FSA, but it still oversees behavioral rules, dispute resolution, and Travel Rule infrastructure. In 2024, it will expand to EPISP, forming a unified SRO. In the future, it will transition to a standard-setting organization.

Consolidation Trends

Widespread losses, rising compliance costs, and concentrated liquidity are driving consolidation from 2026 to 2028. Tier 1 platforms will capture most of the new traffic, while Tier 3 will face mergers or exits. SBI, Monex, and Rakuten will be the main buyers. Scale will become the key to survival, with new entrants more inclined to cooperate rather than register independently.

Offshore Trading Repatriation

Lower tax rates and strengthened enforcement will drive retail repatriation, but leverage (2x limit) and altcoin variety restrictions remain, with some professional traders retaining offshore positions. Institutions, however, are almost entirely repatriating domestically. In terms of derivatives, institutional leverage is expected to return, while retail remains restricted.

Participant Profiles

Japan currently has approximately 12.4 million active crypto users, accounting for about 12% of the adult population, with a penetration rate nearing that of the United States (10-12%). However, the average holding size per user is significantly smaller, with the core user group concentrated among individuals aged 30-40 and with annual household incomes below 7 million yen, primarily trading through exchange mobile apps and rarely using DeFi wallets.

The behavior characteristics of Japanese retail investors sharply contrast with those in South Korea: trading frequency is low, with a focus on BTC and ETH, and a preference for long-term accumulation, as most users trade only a few times each quarter.

The impact of the 2026 tax reform on this foundational layer is not uniform. Active traders will directly benefit from reduced friction, while mainstream accumulation-type users will be less affected by the tax rate cuts. More importantly, the reclassification under the FIEA (Financial Instruments and Exchange Act) will bring legitimacy effects—crypto assets will be officially categorized alongside listed stocks as regulated financial products.

During the transition period from 2027 to 2028, effectively capturing this group of users will become the top business priority for Tier 1 licensed crypto asset service providers (CAESPs).

Nomura 2026 Survey: What Institutions Really Want

According to the 2026 institutional investor digital asset survey jointly released by Nomura and Laser Digital, the intent data from Japanese institutions prior to the FIEA reform is quite valuable. The core finding is that 79% of Japanese institutional investors considering allocating to crypto assets plan to enter the market within three years, with mainstream allocation ratios concentrated in the 2-5% range of assets under management (AUM).

Among the respondents considering crypto asset allocation in the next three years, 79% plan to invest, with 60% expecting allocation ratios between 2% and below 5%. 65% of institutions view crypto assets as a portfolio diversification tool, primarily due to their low correlation with other asset classes.

Interest in products is broad: staking/mining 66%, lending and mortgages 65%, tokenized assets 65%, derivatives 63%. Institutions are pursuing yield and practical applications rather than mere beta exposure. 63% of institutions have clarified specific use cases for stablecoins, including fund management, cross-border payments/foreign exchange, crypto asset investment, and tokenized securities settlement. Among JPY, USD, and EUR stablecoins, those issued by large financial institutions receive the highest trust, directly benefiting projects like Project Pax and JPYSC, and showing greater potential for institutional capital inflow compared to JPYC.

Remaining barriers mainly include weak fundamental analysis frameworks, counterparty risks (default, fraud, asset loss), high volatility, and residual regulatory uncertainties—these issues have shifted from existential risks to operational problems.

How the Four Major Barriers Will Be Broken Down by the 2026 Reforms

Japanese institutional crypto adoption has long been constrained by four structural barriers, and the 2026 reform plan directly addresses these pain points.

• Barrier One: Tax Treatment. Before the 2028 tax reform, corporate crypto gains were taxed at about a 30% corporate tax rate, while individuals faced a maximum tax rate of 55% as miscellaneous income. Although the corporate tax rate is acceptable, it remains higher than the 20.315% capital gains tax on listed stocks, leading asset management companies to lack comparable allocation incentives. The 20.315% separate tax system to be implemented on January 1, 2028, will align personal crypto taxes with those on stocks, and the reclassification under the FIEA will clarify corporate treatment, completely eliminating allocation barriers for retail-oriented institutions.
• Barrier Two: Lack of Spot ETFs. A spot Bitcoin ETF remains the most convenient access channel for institutions, which Japan has yet to launch, with a target implementation date of 2028. Until then, institutional Bitcoin exposure can only be achieved through Metaplanet stocks, overseas ETFs (accompanied by exchange rate and tax complexities), or directly through CAESPs. Each method has structural disadvantages, and the 2028 spot ETF will become the biggest catalyst for unlocking institutional funds.
• Barrier Three: Ambiguity in Accounting and Auditing. Japanese GAAP has long been ambiguous regarding impairment, fair value vs. cost method, and disclosure requirements for corporate crypto holdings. The guidance from the Japanese Accounting Standards Board (ASBJ) in 2024-2025 has clarified that corporate crypto holdings can be recorded at fair value, significantly lowering the threshold for corporate treasury adoption. Coupled with clearer legal classifications under the FIEA, the accounting landscape is much cleaner than it was 18 months ago.
• Barrier Four: Restrictions of the LPS Law on VC Funds. Before the 2026 revision of the LPS Law, Japanese limited partners could not directly hold crypto assets, forcing Japanese Web3 VC funds to adopt intermediary structures in Singapore or the Cayman Islands. The new revision allows direct holdings, which is expected to significantly drive the return of Japanese domestic Web3 VC activities starting in 2027, making local VC funds an important channel for institutional crypto exposure.

Corporate Treasury: The Pioneering Path Opened by Metaplanet

Between 2024 and 2026, the adoption of Bitcoin treasuries by Japanese companies is almost entirely led by a single listed company, Metaplanet Inc., which is currently the third-largest publicly disclosed corporate Bitcoin holder in the world.

Under the leadership of CEO Simon Gerovich, Metaplanet has transformed from a loss-making hotel holding company into a Bitcoin treasury specialist, increasing its holdings from 1,762 BTC at the end of 2024 to 35,102 BTC by December 30, 2025, a growth of about 20 times, through equity issuance, convertible bonds, and warrants.

This model successfully fills three major gaps in the Japanese market: the previous maximum tax rate of 55% on retail crypto gains (until the separate tax takes effect in 2028), the inability of NISA accounts to directly hold Bitcoin, and the absence of a spot Bitcoin ETF. The listed company vehicle resolves all three issues at once, allowing retail investors to gain regulated, NISA-eligible, and equity-wrapped Bitcoin exposure while enjoying corporate tax rates instead of 55%.

Its structural advantages include:

• NISA Eligibility: Metaplanet, as a listed stock, can be included in NISA and iDeCo, while direct holdings cannot. This advantage will continue after the 2028 tax reform.
• Capital Market Leverage: As a listed company, it can scale financing through equity, convertible bonds, and warrants, which individual investors cannot match.
• Bitcoin Revenue Business: In 2025, it generated approximately $55 million in revenue through options and derivatives business, providing continuous cash flow support for further purchases.

The 2026 tax reform will narrow but not eliminate this advantage. Once the tax rate gap disappears, NISA/iDeCo eligibility, capital market access, and Bitcoin revenue business will become core differentiators. The adaptability of NISA and iDeCo is expected to become a major marketing point after 2028.

Metaplanet has become a template for Japan's emerging "Digital Asset Treasury" (DAT) cohort. As of May 2026, 14 listed companies in Japan collectively held approximately 46,245 BTC (about $3.6 billion), with 87% concentrated in Metaplanet.

The main risk for this group is the approval of the spot ETF in 2028, which could lead to funds flowing into lower-cost ETFs, narrowing the current DAT premium of 50%-150% down to 10%-30%. However, companies with real operational businesses will better withstand the impact.

In addition to DAT, large asset management companies such as SBI, Nomura, and Daiwa are building digital asset funds, and private banks are also releasing high-net-worth allocation guidelines for the first time. The legality under the FIEA, the 20% tax parity, and the revision of the LPS Law have collectively created an institutional channel that did not exist 24 months ago.

In summary, Japan's crypto market is currently in a dual-driven phase of retail accumulation and institutional entry. The period from 2026 to 2028 will be a critical window, and seizing the legitimacy benefits of tax reform, addressing institutional barriers, and leveraging corporate treasury templates will determine the competitive positions of various parties in the next cycle.

Who Regulates Cryptocurrency in Japan

Japan's crypto market is expanding rapidly: active users have doubled within three years to over 12 million, accounting for about 12% of the adult population, with user deposits exceeding 5 trillion yen by early 2025.

Crypto regulation in Japan involves multiple departments but can be clearly categorized into several major types:

• Leading regulatory bodies: The Financial Services Agency (FSA) and its market conduct supervision department—the Securities and Exchange Surveillance Commission (SESC).
• Macro and anti-money laundering agencies: The Bank of Japan (BOJ), Ministry of Finance (MOF), Ministry of Economy, Trade and Industry (METI), and the National Financial Intelligence Center (JAFIC), which is under the National Police Agency.
• Industry self-regulatory organizations (SROs): The Japan Virtual Currency Exchange Association (JVCEA) and the Japan Security Token Offering Association (JSTOA).

Instead of introducing each department one by one, it is more effective to group them by their actual regulatory functions.

The three major institutions will jointly regulate licensed crypto exchanges, with a core change in 2026 being the concentration of power in the FSA, while the influence of self-regulatory organizations diminishes. First, the regulatory targets are clarified:

Licensed crypto exchanges in Japan are officially referred to as "Crypto Asset Exchange Service Providers" (CAESP). Any institution serving Japanese users must register with the FSA under the Payment Services Act. The entry barriers are extremely high: before starting operations, they must meet requirements for segregated custody, AML/CFT systems, compliance with the Travel Rule, and strict internal control requirements, and will face ongoing inspections, with violations potentially leading to suspension or revocation of licenses.

• FSA: Decides who can operate. The FSA is the absolute leader, adopting strict pre-approval rather than post-penalty (the U.S. model). The cost is slower growth, but the benefit is that FSA licenses are highly valued, making Japan a safer option for large investors compared to faster-moving markets.
• SESC: Oversees how operations are conducted. The FSA decides on access, while the SESC is responsible for behavioral regulation. Starting in 2026, the SESC will fully extend its stock market regulatory toolkit to the crypto sector for the first time. Notably, the SESC does not impose fines directly but investigates and recommends penalties to the FSA, with major cases referred to the Tokyo Prosecutor's Office. This means that manipulation and insider trading in crypto exchanges are now subject to the same regulatory mechanisms as the stock market.
• JVCEA: Industry self-regulatory organization. JVCEA is the FSA-certified self-regulatory organization for CAESPs, established after the Coincheck incident in 2018. Its core function is not to issue licenses (which is the FSA's power), but almost all CAESPs have joined. Therefore, the FSA issues licenses, and JVCEA is responsible for daily oversight and rule-making.

Stablecoins, Payments, and Anti-Money Laundering

Stablecoins will adopt a separate licensing track, regulated by the FSA as EPISP (Electronic Payment Instrument Service Provider), based on the 2023 stablecoin system. Starting from October 2024, JVCEA will also serve as the self-regulatory organization for EPISP, merging the self-regulatory oversight of CAESP and EPISP, aiming to delegate operational standards to a single entity by the FSA.

The Bank of Japan (BOJ) is not a licensing regulator but influences the environment through three pathways: a long-standing CBDC pilot (now in its third phase), macro statements in the Financial System Report, and supervision of the payment system via BOJ-Net. Its 2025 Financial System Report lists the growth of stablecoins as a future observation point but has not taken restrictive measures, indicating that the BOJ is closely monitoring large bank pilots and JPYC.

JAFIC (Japan's Financial Intelligence Unit) receives suspicious transaction reports from CAESP, EPISP, and banks, publishes typical AML/CFT cases, and represents Japan in the FATF. The FATF gave Japan a "substantial compliance" rating for virtual asset anti-money laundering in its 2023 assessment, making AML one of the few areas in Japan that has been fully established and aligned with global standards.

The Ministry of Finance is responsible for declarations of cross-border crypto transfers under the Foreign Exchange and Foreign Trade Act (FEFTA) and drafts tax policies in collaboration with the FSA. Currently, the global share of yen-pegged stablecoins remains very low, with dollar-pegged tokens accounting for about 99% of the global stablecoin supply, which is precisely the gap that the EPISP system and JPYC aim to fill.

Security Tokens and STO

Security tokens (STO) follow an independent track, distinct from spot crypto and stablecoins. These are security token offerings (STO) representing regulated financial products such as equity, bonds, and real estate rights, issued under the FIEA rather than the PSA. As they are essentially securities, STOs bear full disclosure, suitability review, and custody obligations from the outset, contrasting with spot crypto, which will only acquire similar requirements after reforms in 2026. The self-regulatory organization is JSTOA.

JSTOA is the FSA-certified self-regulatory organization for security tokens, established when the STO market began in 2019. Its scope is narrower than that of JVCEA, covering only entities that issue, distribute, or trade security tokens under the FIEA Type-1 and Type-2 frameworks, with major members including Nomura, Daiwa, SBI, and Mitsubishi UFJ Morgan Stanley.

JSTOA establishes behavioral guidelines for STO platforms, issuer disclosure guidelines, and investor suitability standards, serving as the industry liaison with the FSA on STO matters. From 2024 to 2025, it will focus on improving issuance disclosure templates, promoting tokenized real estate (e.g., Kenedix) and tokenized corporate bonds (Daiwa, Nomura, Mitsubishi UFJ pilot). By 2025, the cumulative issuance scale of STOs is expected to approach hundreds of billions of yen, though the volume is small, growth is rapid.

The FIEA reform now imposes similar disclosure obligations on 105 whitelist spot tokens as on security tokens, blurring the lines between the two asset classes.

Overall, the division of labor is clear: JVCEA leads the rule-making for spot tokens, JSTOA leads STO issuance, and the crossover areas are resolved by issuers' choices and platform structures. For issuers, the disclosure requirements for STOs and spot tracks are converging, although gatekeepers remain independent.

Why 2026 is a Key Year

The regulatory overhaul in 2026 is the core event of the year, triggering almost all downstream market changes. It is not a single bill but a combination of seven interlocked reforms: reclassification of the FIEA, tax adjustments, insider trading prohibitions, disclosure systems, new exchange obligations, SESC empowerment, and amendments to the LPS law.

The seven reforms are drafted by the same FSA team, following the same policy logic. Unlike previous years (2017, 2019-2020, 2022-2023), which addressed only one or two issues at a time, 2026 will package tax, market behavior, disclosure, and intermediary licensing reforms all at once.

Core: Reclassification of FIEA

The most significant reform is the reclassification of crypto assets from "payment instruments" under the Payment Services Act (PSA) to "financial instruments" under the Financial Instruments and Exchange Act (FIEA). This goes far beyond a mere name change; financial instruments must bear the obligation system accumulated over 70 years of Japanese securities law: continuous issuer disclosure, market manipulation prohibitions, insider trading rules, segregated custody, prospectus liability, and SESC supervision.

On April 10, 2026, the Cabinet approved the amendment: 105 crypto assets, including BTC and ETH, will be reclassified as financial instruments, prohibiting insider trading using significant non-public information, requiring token issuers to submit annual disclosures, and raising penalties for unlicensed sales to a maximum of 10 years imprisonment and 10 million yen fines, while amending the LPS law to allow Japanese VC funds to directly hold crypto assets. This law is expected to take effect in the 2027 fiscal year.

For token issuers, the disclosure system is the most critical. Approved token issuers must publish annual reports equivalent to those of listed stock issuers, covering financial status, token supply mechanisms, key personnel, major risks, and significant changes. Failure to report or false reporting will face SESC referral and potential criminal liability.

For VCs, the LPS law amendment eliminates barriers that forced Japanese Web3 funds to flow to Singapore or the Cayman Islands, and it is expected that Japanese domestic Web3 VC activities will significantly return starting in 2027.

105 Token Whitelist and New Powers for SESC

The FSA maintains a limited whitelist, with only 105 tokens eligible for FIEA disclosure treatment and a 20% tax rate, anchored by BTC and ETH, including mainstream large-cap L1s. The use of a whitelist facilitates management but is also more conservative, concentrating gatekeeping power in the FSA.

The reward for investors holding whitelist tokens is tax: profits shift from miscellaneous income (up to about 55%) to a separate tax rate of 20.315%, consistent with listed stocks, and can carry forward losses for three years.

New tokens will transition from the original JVCEA-led screening to a disclosure declaration process under the FIEA, where issuers (or exchanges acting on behalf of unlicensed agreements) submit economic, governance, and risk documents, with the FSA focusing on investor protection rather than market quality judgments, and the whitelist is expected to gradually expand in the future.

Meanwhile, the SESC will gain a complete traditional toolbox for crypto for the first time, including subpoenaing exchange trading records and on-chain data, recommending penalties for illegal gains, referring criminal cases, and initiating market manipulation lawsuits.

The SESC's "2026-2028 Strategy and Policy" will prioritize monitoring the crypto market. The same mechanisms used in the 2024 ANYCOLOR stock manipulation case will now target undisclosed token listings, listing window manipulation, and position operations driven by significant events. Observers claim this could be the clearest insider trading regulatory system for crypto among major jurisdictions globally.

Controversy Over "Overregulation"

Licensed CAESPs will see a significant expansion of compliance boundaries from 2026 to 2027. New obligations layered on top of existing PSA requirements (segregated custody, AML/CFT, Travel Rule, JVCEA behavioral guidelines) will bring exchanges closer to operating as financial instrument operators registered under the FIEA. The new upgraded requirements include:

• Annual submission of a cybersecurity self-assessment (CSSA) based on the FSA framework;
• Liability reserves linked to user asset balances (similar to securities firms' net capital rules);
• Asset retention orders continued from the 2025 PSA amendment;
• Stricter compliance with outbound Transfer Travel Rule;
• New insider trading monitoring systems to identify suspicious patterns before and after significant events.

The FSA acknowledges that about 90% of Japanese exchanges are currently operating at a loss, and the new FIEA disclosures, CSSA, liability reserves, and monitoring will further compress profits and accelerate industry consolidation. Some senior members of JVCEA criticize that this may lead to only a few surviving exchanges in Japan, reducing competitive pressure on listing standards.

The opposing viewpoint argues that Japan's light regulation from 2017 to 2024 has not led to substantial growth, but rather has resulted in costs due to insufficient consumer protection, as seen with Coincheck, DMM Bitcoin, and FTX. The comprehensive plan for 2026 is deemed a necessary cost to facilitate large-scale institutional entry. Both sides have valid points, and the ultimate test will come in 2027-2028, when the integration of CAESP and the expansion of the 105 list will verify whether the FSA's calibration is appropriate.

Open Questions and Timeline

The biggest unresolved issue is DeFi, which aligns poorly with the new framework: the FIEA targets issuers and registered intermediaries, and the FSA currently has no plans to immediately regulate DeFi frontends or smart contract deployers. The actual result is a gray area—DeFi is not banned, but it lacks the consumer protections and tax clarity enjoyed by spot trading on the 105 list.

An optimistic scenario relies on three major catalysts: integration of JPYC with mainstream protocols bringing in native yen revenue, Japanese asset management companies packaging DeFi exposure into regulated products, and tax guidance treating DeFi earnings from the 105 list as equivalent to capital gains. While uncertainty remains until 2028, if achieved simultaneously, Japanese DeFi could transition from a niche to a mainstream product category.

The timeline is crucial, as downstream changes (retail inflow, ETF approvals, large banks launching stablecoins) depend on specific milestones:

* Legislative Phase (April-July 2026): The most predictable phase, with broad support for tax reform, the LDP-Komeito coalition controlling both houses, and a baseline scenario of passage in mid-2026, effective in the 2027 fiscal year. * Implementation Phase (Second half of 2026 to 2027): Execution risks concentrate here, as the FSA needs to establish disclosure templates, insider trading guidelines, CSSA scoring, liability reserves, and listing procedures, each subject to a 30-day public comment period. Delays of 3-6 months into Q1 2027 would not be surprising. * Supporting Milestones: The 20.315% separate tax rate will take effect on January 1, 2028, with the FSA aiming to launch spot BTC/ETH ETFs in 2028, both dependent on the FIEA plan coming into effect.

Part Three: Migration: Digital Currency and Tokenization

Japan's Stablecoin Ecosystem

Japan's path to stablecoin development best reflects the country's regulatory philosophy: first, establish a legislative framework to allow the industry to innovate products within rules, and then approve issuers one by one, with substantive reviews upfront.

Unlike viewing stablecoins as ordinary crypto assets, Japan has established a separate category of "Electronic Payment Instruments" (EPI) under the Payment Services Act (PSA) and clearly distinguishes between two major regulated roles:

* Issuers: Limited to three types of highly credible entities—licensed banks, trust companies, and registered money transfer operators. Each issuer must ensure a 1:1 redemption and hold fully segregated, low-risk reserve assets, making Japanese stablecoins closer to electronic money rather than algorithmic tokens. * Distributors (EPISP): Exchanges and intermediaries responsible for providing stablecoin services to end users. The FSA certified JVCEA as its self-regulatory organization in 2024, unifying trading venues and stablecoin distribution regulation under the same entity.

The PSA amendment passed in 2022 and effective in June 2023 established the EPI category, two full years ahead of any issuer actually launching products. JPYC was approved in August 2025 and officially registered in April 2026, becoming the first success of this pipeline; the large bank pilot is the second.

The biggest difference between Japan and other global markets is the high level of institutional participation. Leading US issuers like Circle and Tether are primarily crypto-native fintechs operating in an evolving regulatory environment; while the European MiCA electronic money token regime has birthed a few new issuers, traditional financial institutions have limited involvement.

Japan's first three reliable issuance paths are distinctly different: JPYC (fintech), large bank pilots from MUFG/SMBC/Mizuho (Project Pax), and JPYSC from SBI and a new trust (trust bank alliance). This includes one fintech, three large banks, and one trust bank alliance, making it unique among major global markets.

The 2023 EPI framework allows for three domestic issuance structures: money transfer, banks, and trust banks, while reserving a fourth purely distribution path for approved foreign tokens. Although the reserve and operational rules differ among the three domestic structures, the final products are highly consistent—fully backed, redeemable on-chain yen tokens.

Money Transfer Issuer: JPYC

Money transfer provider licenses are the least demanding among the three domestic EPI structures. Issuers keep all reserves in bank deposits and short-term Japanese government bonds, redeeming tokens at face value and assuming PSA obligations to the FSA. Capital requirements and listing times are lower than those for banks or trust banks, with the trade-off being a limit on individual transaction amounts, making it suitable for fintech-led yen stablecoins targeting retail and small business users.

JPYC is the first product of this path. JPYC Inc. was established in 2019 and had already operated a prepaid payment predecessor product before the EPI framework was introduced, issuing approximately 30 billion yen and integrating with Visa prepaid cards, Gifty Box, and regional bank systems. This operational history provided a reliable record when the FSA initiated EPI reviews. The FSA signaled approval in August 2025, and JPYC was officially registered on April 28, 2026, making it Japan's first yen stablecoin approved by the FSA and in commercial operation.

Distribution mainly relies on Sony Bank, regional bank partners, and fintech wallets. As long as the large bank path remains B2B, JPYC's competitive position is relatively secure. However, once large banks launch retail tokens, their brand and distribution advantages may compress JPYC's space, although JPYC's first-mover advantage at the fintech wallet level will likely persist.

Large Bank Issuer: Project Pax

Bank-issued EPIs are stablecoins minted directly from the balance sheets of licensed Japanese banks, enjoying legal treatment equivalent to deposits, backed by the banks' own prudent capital. This structure has the highest trust level and the largest individual transaction limits, but operational complexity is high. Only banks with a global correspondent network can realistically implement this, which also determines its primary service for B2B and interbank settlements rather than retail.

Project Pax is the first concrete case of this structure, led by MUFG, SMBC, and Mizuho, with technical support from Progmat (MUFG incubated), Datachain, and TOKI, receiving support from the FSA in November 2025. This design retains SWIFT messaging for enterprise client frontends while replacing correspondent bank settlements with on-chain stablecoin transfers, covering Ethereum, Polygon, Avalanche, and Cosmos networks, compressing settlement times from days to minutes and eliminating multi-hop foreign exchange steps.

The potential scope is enormous. MUFG alone has over 240 international subsidiaries, with SMBC and Mizuho having comparable network scales. The first use cases involve internal fund flows within the group (such as dividends, inter-company transfers, and acquisition payments), with corporate trade financing being a natural extension.

Trust Bank Issuer: SBI and JPYSC

Specified Trust Beneficial Interests (Specified TBI) are trust bank instruments. Reserves are placed in regulated trusts, with tokens representing beneficial rights to that trust. The 2022 PSA amendment specifically excluded Specified TBI from the FIEA "securities" definition, avoiding the disclosure burden of security-type tokens while retaining asset segregation for trust-level clients.

The key structural advantage is that trust tokens can circulate among multiple banks and intermediaries, rather than being tied to a single balance sheet. This makes them particularly suitable as settlement assets for tokenized securities and RWA platforms.

JPYSC is the first issuer of this structure, issued through a new trust bank within the SBI and Startale alliance, specifically providing settlement assets for tokenized stocks, RWA, and DeFi on the Strium Network (developed by SBI and Startale).

Its competitive strategy is vertical integration: SBI simultaneously owns a stablecoin (JPYSC), L1 (Strium), exchange layer (SBI VC Trade and the pending acquisition of bitbank), and STO venues (SBI Securities and ODX).

Capital investment matches ambition. Startale completed a $63 million Series A funding round led by SBI Group and Sony Innovation Fund in early 2026; SBI subsequently directly invested 8 billion yen (approximately $50 million) in March 2026, making this tokenization expenditure exceed that of any other single institution in Japan.

Foreign Stablecoin: USDC Case

USDC is the first practical test of the EPI framework's acceptance of foreign-issued stablecoins. On March 26, 2025, SBI VC Trade launched USDC, becoming the first foreign stablecoin approved for distribution in Japan, followed by Binance Japan, bitbank, and bitFlyer.

It adopts a distributor model: EPISP acts as a regulated intermediary in Japan, rather than Circle distributing directly. Circle retains its identity as a foreign issuer, while the Japanese EPISP assumes AML and consumer protection compliance responsibilities.

In January 2026, the FSA further relaxed access rules for foreign trust-based stablecoins, but imposed strict collateral standards: foreign bonds used for reserves must have a top credit rating, and the issuing country's outstanding debt must reach at least 100 trillion yen (approximately 65 billion USD). This threshold effectively limits eligible foreign bond reserves to top sovereign nations, such as U.S. Treasury bonds, German government bonds, and Japanese government bonds. Even by global stablecoin standards, this requirement is extremely conservative.

The practical effect is to exclude most non-U.S. and non-Japanese issuers from large-scale use of non-yen collateral. The British GBP stablecoin struggles to meet the standards alone, while Brazilian or Mexican stablecoins are essentially excluded. This framework thus favors dollar-collateralized stablecoins (like USDC) and yen-collateralized stablecoins (like JPYC, JPYSC, and large bank tokens), setting high barriers for other participants.

The strategic interpretation is that Japan welcomes high-grade foreign stablecoins like USDC but will not become a haven for weak collateral issuers. This aligns with the FSA's consistent stance—low tolerance for interest rate arbitrage, high requirements for reserve quality, and a strong preference for transparent, supervised counterparties.

Comparison of Four Types of Issuers

The comparison clearly shows that Japan's stablecoin ecosystem is intentionally segmented by use case rather than competing for the same market share. JPYC dominates retail and fintech distribution, large banks pilot B2B cross-border flows, SBI/new trust leads RWA and tokenized securities settlement, and USDC serves crypto trading and DeFi. Each type of issuer is structurally constrained by license type, reserve composition, and distribution channels, directing them to their respective niche markets.

The core uncertainty from 2026 to 2028 lies in whether large bank pilots will expand from B2B cross-border to retail tokens, which would directly impact JPYC. Currently, MUFG, SMBC, and Mizuho have all indicated that retail is not within scope, but the bank's issuance of EPI structure technically allows it, and competitive pressure may push at least one large bank to eventually enter retail. JPYC's defensive strategy is to lock in fintech, regional banks, and Sony Bank distribution channels before large banks enter retail, with this race against time expected to become evident in 2027.

For external participants, the choice of integration paths is straightforward: use JPYC for consumer or fintech products, large bank channels for institutional B2B settlements, SBI/Startale stack for RWA and tokenized equity, and USDC for crypto trading. Japan does not have a single "Japanese stablecoin" but rather four distinct stablecoins, each with its focus, which is relatively rare globally and one of Japan's structural advantages.

Beyond Stablecoins: Tokenized Deposits and CBDC

The above content covers three paths for EPI-based stablecoins, but there are also two digital currency structures running in parallel that are equally important for institutional cross-border business: tokenized bank deposits and the Bank of Japan's (BOJ) CBDC digital yen pilot. The two belong to different types of digital currencies, each with its issuer, legal basis, and use.

Tokenized Bank Deposits and DCJPY

Tokenized bank deposits represent a direct claim on the liabilities of regulated bank deposits. They differ from EPI stablecoins (which are redeemable payment instruments against segregated reserves) and from CBDCs (central bank currencies). Their core feature is that the underlying asset is commercial bank deposits, thus carrying the credit of that bank and existing within the banking system rather than outside it.

DCJPY is DeCurret Holdings' digital yen deposit token, serving as Japan's standard for tokenized bank deposits. It runs parallel to JPYC but has a completely different legal structure: JPYC is a funds transfer EPI, while DCJPY is a bank deposit tokenized claim supervised by the BOJ, rather than an EPI regulated by the PSA.

DCJPY primarily targets B2B and institutional settlements, not open to retail, and connects directly with bank core systems through the DeCurret alliance (including IIJ, MUFG, SMBC, Mizuho, Resona, and several regional banks), specifically designed for DvP settlement of tokenized securities. It has been applied in multiple STO settlement demonstrations at SBI Securities, forming part of Japan's digital currency stack alongside JPYC (retail) and Project Pax (cross-border B2B).

Bank of Japan Digital Yen Third Phase Pilot

The digital yen is a central bank digital currency (CBDC) directly issued by the Bank of Japan, as a liability of the central bank, rather than a commercial bank (like DCJPY) or a private issuer (like EPI stablecoins). As a sovereign currency, it will be a risk-free settlement asset at the base of the stack, setting a benchmark for private sector tokens.

The BOJ digital yen pilot will enter its third phase from 2024 to 2026, focusing on technical integration with private sector payment systems rather than retail issuance. The BOJ has repeatedly emphasized that it has not yet decided on the issuance of a retail CBDC, with the third phase primarily being technical preparatory work.

The pilot itself has limited significance for the digital yen; more importantly, it sends a standardization signal to private stablecoin and deposit token issuers. The BOJ has publicly stated that JPYC, Project Pax, and JPYSC are private experiments it tracks but does not lead, thus the two systems are intentionally designed to be complementary.

If the digital yen is eventually commercialized (the likelihood before 2028 is low), it will coexist with the EPI stack rather than replace it. This position is similar to the European Central Bank's digital euro, differing from China's e-CNY, which aims to replace private payments.

On-Chain Migration: Tokenization

Tokenization involves issuing and trading traditional financial assets on public chains. Between 2024 and 2026, Japan quietly built every layer of this market: asset legal status, underlying chains, and settlement currencies. The asset side relies on the FIEA securities token framework, while the settlement side relies on JPYSC and tokenized deposits, with infrastructure including proprietary chains and shared chains.

Its unique advantage stems from a special provision in the securities law: the JASDEC exemption excludes the central securities depository from the securities token path, allowing the ledger itself to serve as the legal record of ownership. This provision permits the simultaneous production of two diametrically opposed architectures: the proprietary vertical stack led by SBI and the neutral utility model led by Progmat and BOOSTRY. Both ultimately rest on a settlement currency base that no single institution can monopolize.

The period from 2026 to 2028 is a window for these components to transition from announcement to production. The tokenized stock platform plan by SBI and Startale is set to launch on the Strium Network in 2027, while the tokenized bond pilots by Daiwa, Nomura, and MUFG are also moving from sandbox to limited production in 2026.

JASDEC Exemption: Why Japan Can Build a Proprietary Stack

This is a key point in Japan's market structure that is easily overlooked. According to the FIEA, securities tokens are considered "electronically recorded transferable rights" (ERTR) and do not need to go through Japan's central securities depository JASDEC (with the exception of government bonds).

JASDEC is Japan's only central securities depository (CSD) providing comprehensive securities settlement infrastructure. For tokenized securities, the on-chain token itself becomes the legal record of rights and their transfer.

The core of ERTR lies in classification. The 2019 FIEA amendment (effective May 2020) established this category. The underlying rights, typically low liquidity "Type II" rights, are considered securities, and once tokenized and freely transferable, they upgrade to Type I securities (the highest disclosure category, same as listed stocks and bonds). It is precisely because the ledger makes it easy to distribute widely that any provider or intermediary must register as a Type I financial product trader, and ERTR is explicitly excluded from the PSA's definition of "crypto assets," cleanly placed under securities law rather than the crypto regime.

Two details are worth noting: the exemption applies to the recording and transfer layer, not the entire securities regulation; ERTR still bears the full Type I disclosure and licensing obligations, which are actually heavier than the original Type II treatment of the underlying rights, thus this "de-regulation" is more structural than lenient.

Only securities records escape JASDEC, while the cash settlement leg still operates through shared facilities like BOJ-NET and tokenized deposits.

In March 2026, when SBI issued 10 billion yen "SBI START Bonds," it recorded on the ibet for Fin blockchain rather than the traditional JASDEC system, fully realizing electronic processing from issuance to redemption.

It is this structural fact that makes proprietary stacks legally possible. The law assigns the functions of transfer agents and CSDs to the ledger rather than mandating a single public utility, allowing private groups like SBI to own that function end-to-end.

Proprietary Stack: The True Meaning of Vertical Integration

Since the ledger itself becomes the record system, a corporate group can simultaneously own every layer of the tokenization chain: asset issuers, settlement assets, blockchain, brokers, and trading venues.

In the Western model, these are typically handled by different, often co-owned institutions. The collaboration announced by SBI and Startale in August 2025 is Asia's clearest attempt at "full-stack ownership": building a one-stop on-chain venue for tokenized stocks and RWA on the Strium Network. Strium is an L1 specifically designed for this purpose, integrating tokenized equity trading, JPYSC settlement, DeFi composability, and a bridge to Ethereum.

This concentration is both the essence of the whole and the source of all controversy.

Neutral Utility Model: Progmat and BOOSTRY

The second architecture is the neutral utility model, which may have more long-term significance. Unlike the proprietary stack that concentrates ownership in a single group, this model intentionally aims for shared ownership among competitors.

The closest Japanese case is Progmat, which MUFG intends to spin off as a neutral national infrastructure entity rather than a subsidiary of a trust bank, aiming to allow competitors to jointly own and build upon it. Its shareholder structure resembles that of a public utility: Mitsubishi UFJ Trust holds 49%, NTT Data 13.5%, Mizuho Trust, SMBC Trust, and SMFG each hold 7.5%, while SBI and JPX (the operator of the Tokyo Stock Exchange) each hold 5%, with Datachain also having a stake.

In early 2026, Progmat will migrate over $2 billion in tokenized real estate and bonds to a dedicated Avalanche L1, achieving cross-chain DvP. Nomura's BOOSTRY operates ibet for Fin chain, serving as the second neutral platform and leading public STO issuance. ODX's "START" PTS (Japan's first ST secondary market) is 70% owned by SBI, 20% by SMBC, and 5% each by Nomura and Daiwa.

The Landscape of Tokenized Assets Continues to Expand

With the assets, chains, and settlement layers in place, the focus shifts to the actual objects being tokenized. Currently, they can be sorted by asset class, observing the scale of those that have truly been issued.

The issuance of security tokens (STO) under the FIEA has been slow since SBI e-Sports completed Japan's first FIEA STO in 2020, but a turning point appeared in 2025: an additional issuance of 165 billion yen, bringing the total to 333.3 billion yen, involving 82 tokens, doubling from the previous year.

Growth is highly concentrated: real estate accounts for about 85% of all issuances, followed by corporate bonds, while others remain at pilot scale. Below is a summary of each asset class in order of current scale, assessing long-term opportunities.

Real Estate: The Ballast (140.8 billion yen in 2025)

Tokenized real estate is the only sector that has achieved real scale, dominating Japan's issuance volume.

This sector is led by SBI-affiliated Digital Securities and Kenedix, the latter having completed Japan's first real estate STO in August 2021, subsequently issuing about 250 billion yen covering 16 products. Both issue tokenized partial ownership of Japanese commercial real estate.

The mechanism's advantage lies in significantly lowering the minimum investment threshold for previously illiquid assets, opening institutional-grade real estate to retail investors. SBI acquired a 20% stake in Digital Securities in early 2026, indicating its intention to integrate this sector into the Strium ecosystem.

Corporate Bonds: Fast Follower (204 billion yen in 2025)

Although the scale of tokenized bonds is an order of magnitude smaller than real estate, it is growing rapidly and has the strongest institutional support.

The three leading brokerages are all piloting: Daiwa and MUFG Progmat collaborated on tokenized bonds in 2023, Nomura's Komainu custody arm supports institutional digital asset settlement, and MUFG plans to issue its first publicly offered security token bond through Progmat by the end of 2025.

SBI's issuance of 10 billion yen "SBI START Bonds" in March 2026 will push retail tokenized bonds into production. This sector is expected to explode after the FIEA's expanded tokenization framework is fully launched in 2027-2028.

Private Equity and Fund Interests: Early Pilots (2.4 billion yen in 2025)

Tokenized private equity and collective investment plan interests are still at pilot scale but naturally match the ERTR structure, which is designed around trust beneficiary rights and fund interests.

As the security token framework matures, this sector is most likely to benefit, as tokenization directly addresses the transfer and accounting frictions that historically rendered these assets illiquid.

REITs and Other Assets: The Next Blue Ocean (1.4 billion yen in 2025)

Tokenized REITs (the on-chain version of J-REITs) have not yet been launched but are expected to follow quickly once the regulatory framework matures.

Along with other niche real estate structures, they represent the expanding edge of the tokenized universe. The arrival of 2027-2028 will see a universe of tokenized assets rather than a single product line.

Opportunity Outlook

Even under conservative estimates, the total addressable market for tokenization is vast. A joint study by BCG and Ripple predicts that by 2033, the global market for tokenized assets will reach $18.9 trillion, with Asia expected to contribute significantly.

Whether Japan can capture a larger share depends on the current regulatory and infrastructure foundations in place, with the real test to be reflected in the growth rates of issuance and trading volumes in 2027-2028.

Japan is quietly building the most institutionally attractive on-chain financial ecosystem in Asia and even globally, with institutional confidence and forward-looking infrastructure. The years 2026-2028 will be a key window to observe the real landing of this major migration.

Part Four: Outlook

The single variable that will most impact the overall outlook is the effective date of the FIEA reform package. If delayed by six months, all other catalysts will also be postponed; if advanced, the entire downstream timeline will be compressed. Therefore, closely tracking the progress of the FSA's consultation on sub-rules in the second half of 2026 is the most leveraged action for any participant interested in this argument.

Below is a calendar of tactical catalysts worth monitoring before 2027. Each event is either a regulatory milestone, a corporate execution milestone, or a market funding flow inflection point. Tracking these signals in order can help early judgment on whether a bear market, baseline scenario, or bull market is unfolding.

First, the end of the parliamentary session in June 2026 is a critical checkpoint for the FIEA amendment. The progress of the bill in the Financial Services Committee, the level of opposition party involvement, and any amendments passed will signal the strength of political support and execution pace.

Second, the FSA's consultation track for sub-rules in the second half of 2026 is the phase with the highest execution risk. The FSA is expected to release draft sub-rules covering disclosure templates, insider trading guidelines, CSSA scoring methods, liability reserve calibrations, and listing application procedures. Each draft will have a 30-day public consultation period, and tracking the timeline and breadth of industry feedback can provide early signals for the FIEA effective date.

Third, the commercial scaling of JPYC in 2026-2027 is the most observable stablecoin indicator. Watch for announcements of its collaborations with regional banks, progress on Sony Bank integration, and B2B corporate treasury pilots.

Fourth, Project Pax's target for production launch in 2027 is a test of large banks' execution capabilities. Monitor the joint statements from MUFG/SMBC/Mizuho transitioning from pilot to limited production B2B settlement, the first announced trading volumes, and SWIFT integration milestones. The production launch of Pax is highly correlated with broader institutional adoption of the yen stablecoin track.

Fifth, the mainnet launch of Strium Network in 2026-2027 is a test of tokenization infrastructure. Watch for the transition from testnet to mainnet, the launch of the validator set, the first tokenized stock issuances, and the integration status of JPYSC.

Sixth, the approval window for spot BTC ETFs in 2028 is the largest single funding flow catalyst on the horizon. The FSA has expressed intent but has not provided specific timing commitments; watch for the FSA's consultation documents on the spot crypto ETF framework in 2027, applications from major Japanese asset management companies (Nomura, Daiwa, SBI Securities), and public statements from FSA leadership regarding timing.

Stepping back, all parts tell a story: Japan is not pursuing the fastest or freest but is patiently building the most trustworthy crypto market.

Thus, the most likely outcome is not a frenzy but a quiet integration into the norm. Funds will flow back, institutions will first standardize allocations, more streamlined exchanges will begin to profit, and tokenization will grow into everyday infrastructure. Looking back, 2026 may not be remembered as "the year crypto arrived in Japan," but rather as "the year crypto became part of Japan's financial pipeline."
