Japan has long been at the forefront of cryptocurrency regulation, striving to balance innovation with financial stability and consumer protection. One of the most notable aspects of its regulatory framework is a surprising limitation: Japanese residents cannot directly purchase major stablecoins like USDT or USDC using Japanese yen on domestic licensed exchanges. This restriction may seem counterintuitive in a tech-savvy, crypto-friendly nation—but it stems from a deliberate and carefully structured legal framework introduced in 2023.
Understanding this requires a deep dive into Japan’s updated financial regulations, the nature of stablecoin issuance, and how global digital assets interact with localized laws.
The 2023 Payment Services Act Amendment: Japan’s Stablecoin Law
In June 2023, Japan enacted a significant amendment to its Payment Services Act (PSA), commonly referred to as the Stablecoin Law. This legislation marked a pivotal moment in Japan’s approach to digital currencies—particularly stablecoins used for payments.
Key Provisions of the New Law
- Eligible Issuers Only: Only licensed banks, trust companies, or registered funds transfer service providers can issue stablecoins recognized as “electronic payment instruments” under Japanese law.
- Currency Peg Requirement: These stablecoins must be pegged to the Japanese yen and redeemable at face value.
- Reserve Asset Safeguards: Issuers must hold 100% reserves in safe, liquid assets—such as cash deposits in regulated financial institutions—to back every stablecoin issued.
- Regulatory Oversight: Intermediaries like exchanges that handle these stablecoins must comply with strict anti-money laundering (AML), know-your-customer (KYC), and operational transparency requirements.

This legal definition effectively excludes foreign-issued USD-pegged stablecoins like USDT (Tether) and USDC (USD Coin) from being officially recognized or traded against the yen on domestic platforms.
Why USDT and USDC Don’t Qualify Under Japanese Law
Despite their widespread use globally, USDT and USDC fail to meet Japan’s issuer eligibility criteria.
The Problem with Issuance Structure
- USDT is issued by Tether Limited, a private company based outside Japan with no banking license under Japanese jurisdiction.
- USDC is managed by Circle, a U.S.-based fintech firm operating through the Centre Consortium, which also lacks authorization as a Japanese financial institution.
Even if these stablecoins are fully backed and audited, the identity and regulatory status of the issuer matter more than the asset backing under Japan’s current framework. The law prioritizes institutional accountability over technological functionality.
Regulatory Caution and Risk Management
Japan’s Financial Services Agency (FSA) and the Japan Virtual Currency Exchange Association (JVCEA)—the self-regulatory body for crypto exchanges—have consistently emphasized risk mitigation.
- Transparency Concerns: Past controversies surrounding Tether’s reserve audits have made regulators wary.
- Systemic Risk: Allowing unregulated foreign entities to issue widely used payment tokens could expose Japan’s financial system to external shocks.
- Legal Clarity: Domestic compliance ensures clear jurisdiction, dispute resolution mechanisms, and consumer recourse.
As a result, exchanges like Coincheck and bitFlyer are prohibited from offering direct JPY/USDT or JPY/USDC trading pairs.
What Options Do Japanese Users Have?
While direct purchases aren't allowed, users still have pathways to access USDT and USDC—but with important caveats.
1. Use of Overseas Exchanges
Japanese residents can register on offshore cryptocurrency platforms that support JPY deposits or peer-to-peer (P2P) trading. However:
- These services are not regulated by the FSA.
- Users assume full responsibility for compliance and security risks.
- Some banks may flag or block transactions related to foreign crypto platforms.
2. Deposit-Only Access on Domestic Platforms
A few Japanese exchanges may allow users to deposit existing USDT or USDC for trading against other cryptocurrencies (e.g., BTC or ETH), provided they meet internal risk assessments. However:
- There is no guarantee this will remain permitted.
- No major exchange currently offers yen-funded entry points into these stablecoins.
3. The Rise of Japanese Yen-Backed Stablecoins
The new law opens the door for domestically issued yen-pegged stablecoins, such as:
- JPYC (developed by Tokyo-based STP Corporation)
- New entrants from major banks and financial groups
These tokens are designed to comply with the PSA amendment and could become the standard for regulated digital payments within Japan.

Frequently Asked Questions (FAQ)
Q: Can I buy USDC in Japan now?
A: As of mid-2025, SBI VC Trade—a licensed Japanese exchange—has announced limited availability of USDC for purchase with yen. This marks a potential shift, possibly due to Circle establishing a local presence or partnership. However, this remains an exception rather than the norm across the industry.
Q: Is it illegal for Japanese citizens to own USDT or USDC?
A: No. Owning foreign stablecoins is not illegal. However, purchasing them directly with yen via domestic exchanges is restricted due to regulatory non-compliance.
Q: Will USDT ever be tradable with yen in Japan?
A: Only if Tether Limited establishes a subsidiary licensed under Japan’s funds transfer regulations—or partners with a qualified financial institution. Until then, it remains excluded.
Q: Are Japanese-issued stablecoins safe?
A: They are subject to rigorous oversight. Issuers must undergo regular audits, maintain full reserves, and report to the FSA, making them among the most secure stablecoin options available.
Q: How does this affect crypto trading in Japan?
A: It limits arbitrage opportunities and cross-border liquidity but enhances investor protection. Traders rely more on BTC and ETH as intermediaries when moving value across chains or markets.
The Bigger Picture: Innovation vs. Control
Japan’s approach reflects a broader philosophy: regulated innovation over unfettered experimentation. While countries like the U.S. or Singapore embrace global stablecoins with lighter-touch frameworks, Japan chooses control, clarity, and consumer safety.
This doesn’t mean isolation—it means preparation. By building a compliant domestic ecosystem first, Japan aims to create a resilient foundation for future digital currency adoption, including potential integration with Central Bank Digital Currencies (CBDCs) and Web3 applications.

Conclusion
The inability to buy USDT or USDC directly with yen in Japan is not a technical limitation—it's a deliberate regulatory choice rooted in the 2023 amendment to the Payment Services Act. By restricting stablecoin issuance to licensed domestic institutions and requiring full reserve backing, Japan prioritizes financial stability and consumer trust over rapid market expansion.
While this creates short-term friction for users seeking global stablecoins, it paves the way for a new generation of compliant, transparent, and locally governed digital currencies. As the landscape evolves—with signs of Circle expanding into Japan—the door may gradually open for select foreign stablecoins that adapt to local rules.
For now, Japan stands firm: innovation is welcome, but only within clearly defined boundaries.
