The rise of crypto-assets (暗号資産 - angō shisan) has brought both innovative financial opportunities and significant risks for users. Recognizing this, Japan has implemented a comprehensive regulatory framework under the Payment Services Act (PSA) (資金決済に関する法律 - Shikin Kessai ni Kansuru Hōritsu) that places a strong emphasis on user protection. Crypto-Asset Exchange Service Providers (CAESPs) (暗号資産交換業者 - angō shisan kōkan gyōsha) registered in Japan are subject to a wide array of obligations designed to safeguard the interests of their customers. These measures range from mandating extensive information disclosure and ensuring fair business practices to requiring robust internal systems and employee training.

This article explores the key pillars of user protection that CAESPs in Japan must adhere to, providing an in-depth look at how the regulatory system aims to create a safer environment for individuals and businesses engaging with crypto-asset services.

The Legal Bedrock: PSA Article 63-10

The primary legal basis for many user protection measures is Article 63-10 of the PSA, titled "Measures Concerning the Protection of Users, etc." (利用者の保護等に関する措置 - riyōsha no hogo-tō ni kansuru sochi). This article empowers the relevant authorities to stipulate detailed requirements through Cabinet Office Ordinances, which are then further elaborated in guidelines issued by the Financial Services Agency (FSA). These provisions collectively form a multi-faceted shield for users.

Key Pillars of User Protection in Japan's Crypto-Asset Sector

The user protection framework for CAESPs in Japan can be understood through several key pillars:

I. Comprehensive Information Disclosure to Users (利用者に対する情報提供 - riyōsha ni taisuru jōhō teikyō)

Transparency is fundamental to enabling users to make informed decisions. CAESPs are required to provide extensive information both before a user enters into a transaction or service agreement and on an ongoing basis.

A. Pre-Contractual and Pre-Transactional Information:
Before a user opens an account or engages in a transaction, CAESPs must provide clear and sufficient explanations regarding:

1. CAESP Identification: The name, address, and registration number of the CAESP.
2. Description of Crypto-Assets: Detailed information about each crypto-asset handled, including its name, characteristics, the technology it uses, and, critically, the inherent risks associated with it, such as high price volatility (価格変動リスク - kakaku hendō risuku). This includes explaining that crypto-assets are generally not legal tender.
3. Fees and Charges (手数料等 - tesūryō-tō): A clear breakdown of all fees, remuneration, or expenses that the user may incur for transactions, account maintenance, or other services. This should include the calculation method if exact amounts cannot be determined in advance.
4. Transaction Execution: How user orders for buying, selling, or exchanging crypto-assets will be processed and executed. This includes information about order types, execution venues (if applicable), and potential delays.
5. Segregated Management of Customer Assets: A detailed explanation of how the CAESP manages and protects users' fiat currency and crypto-assets separately from its own proprietary assets. (While this is a standalone obligation under PSA Art. 63-11, its disclosure is a key user protection element).
6. Cybersecurity Measures: An overview of the main cybersecurity measures implemented by the CAESP to protect its systems and user information.
7. Complaint Handling and Dispute Resolution: Information on how users can lodge complaints with the CAESP and the availability of external dispute resolution mechanisms, including designated Alternative Dispute Resolution (ADR) services.
8. Specific Transaction Risks: For more complex or higher-risk transactions, such as margin trading or crypto-asset derivatives (if offered by the CAESP and permitted under regulations), specific and prominent risk warnings are required.
9. User-Side Security: Guidance for users on how to securely manage their own private keys, passwords, and other account credentials to mitigate risks of unauthorized access from their end.
10. No Government Guarantee: An explicit statement that the value of crypto-assets is not guaranteed by the government or any central bank (unless it's a specifically designated CBDC, which is a separate matter).

B. Method and Manner of Information Delivery:
The information must be provided in writing or via electronic means (with prior user consent). Crucially, the explanations must be accurate, clear, and presented in a manner that is not misleading and is understandable to the user, taking into account their level of knowledge and experience with crypto-assets. Simply providing a lengthy, jargon-filled document is not sufficient; the CAESP must make reasonable efforts to ensure genuine comprehension.

C. Ongoing Information During the Business Relationship:
The duty to inform is not a one-time event. CAESPs must provide users with:

• Trade Confirmations: Prompt confirmation of executed transactions, detailing the crypto-asset, quantity, price, fees, and transaction date/time.
• Account Statements: Periodic statements showing account balances (fiat and each crypto-asset) and transaction history.
• Material Changes: Notification of any significant changes to terms and conditions, fees, services offered, or security procedures.

II. Prohibition of Certain Acts and Adherence to Fair Business Practices

To prevent abuse and ensure a level playing field, Japanese regulations impose several prohibitions and expect fair conduct from CAESPs:

1. Prohibition of Misleading Representations (誤認防止のための説明 - gonin bōshi no tame no setsumei): CAESPs are strictly prohibited from providing false information or making statements that could mislead users concerning material facts. This includes misrepresenting the nature of crypto-assets, their potential returns, associated risks, or the CAESP's own services and security.
2. Restrictions on Solicitation (勧誘 - kan'yū):
   • Unsolicited Contact: There are restrictions on unsolicited calls or visits for the purpose of soliciting crypto-asset transactions, particularly for high-risk products.
   • High-Pressure Tactics: Using coercive language or behavior to pressure users into transactions is forbidden.
   • Providing Definitive Assertions on Uncertain Matters: CAESPs cannot make definitive positive assertions about future price movements or guarantee profits, as these are inherently uncertain.
3. Prohibition of Unfair Trading Practices: Practices such as front-running (trading for the CAESP's own account based on advance knowledge of customer orders) or other manipulative trading activities are prohibited to ensure market integrity.
4. Management of Conflicts of Interest: CAESPs must identify potential conflicts of interest between themselves (or their affiliates) and their users, or between different users, and establish appropriate systems to manage such conflicts fairly. This may involve disclosure, establishing internal information barriers, or declining certain transactions.
5. Appropriate Advertising and Marketing: All advertising and marketing materials must be truthful, not misleading, and clearly indicate the risks involved in crypto-asset transactions. They should avoid overly speculative inducements or downplaying risks. Self-regulatory organizations (SROs) like the Japan Virtual and Crypto assets Exchange Association (JVCEA) have established detailed advertising guidelines that member CAESPs must follow, covering aspects like risk warnings, prohibitions on guaranteeing profitability, and responsible messaging.

III. Establishment of Robust Internal Systems and Governance for User Protection

Effective user protection requires more than just external disclosures; it necessitates strong internal frameworks within the CAESP. (This is detailed in Cabinet Office Ordinance on Virtual Currency Exchange Service Providers, Article 19, stemming from PSA Art. 63-10, Paragraph 4).

1. Development of Comprehensive Internal Rules and Procedures (社内規則等 - shanai kisoku-tō): CAESPs must establish and maintain detailed internal rules, policies, and operational procedures covering all aspects of their user protection obligations. This includes procedures for:
   • Onboarding new users (including KYC and risk assessment).
   • Providing pre-contractual information.
   • Executing and confirming transactions.
   • Handling user inquiries and complaints.
   • Managing user assets.
   • Ensuring data security and privacy.
   • Employee conduct and training.
2. Effective Employee Training and Education (研修等 - kenshū-tō): All relevant employees, especially those in customer-facing roles (e.g., sales, support) and those involved in transaction processing or system management, must receive regular and effective training. This training should cover:
   • The nature and risks of crypto-assets handled by the CAESP.
   • Applicable laws, regulations, and internal rules concerning user protection.
   • Procedures for explaining complex products and risks clearly to users.
   • How to handle user inquiries and complaints appropriately.
   • AML/CFT obligations and cybersecurity awareness.
3. System for Handling User Inquiries and Complaints (苦情等への対処 - kujō-tō e no taisho):
   • Accessible Channels: CAESPs must establish readily accessible and clearly communicated channels through which users can submit inquiries and complaints (e.g., dedicated phone lines, email addresses, online forms).
   • Prompt and Fair Investigation: Procedures must be in place to ensure that all complaints are investigated thoroughly, impartially, and in a timely manner.
   • Clear Communication: Users should be kept informed about the status of their complaints and the outcome of investigations.
   • Record Keeping: Detailed records of all complaints, the investigation process, and their resolution must be maintained.
   • Linkage to ADR: Users must be informed of their right to use designated ADR services if they are not satisfied with the CAESP's internal resolution.
4. Consideration of Customer Suitability (適合性の原則 - tekigōsei no gensoku): While the PSA does not codify a "suitability rule" for all crypto-asset transactions in the same way the FIEA does for securities, the spirit of ensuring that products and services are appropriate for users is strongly embedded in the user protection framework. This involves:
   • Making efforts to understand a user's knowledge of crypto-assets, investment experience, financial situation, and transaction purposes, especially when offering high-risk products or services like margin trading.
   • Tailoring explanations and risk warnings to the user's perceived level of understanding.
   • Refraining from recommending transactions or strategies that are clearly unsuitable for a particular user.

IV. Security of User Assets and Information (Fundamental to User Protection)

While covered in-depth by other specific articles of the PSA (Art. 63-11 for segregated asset management and Art. 63-8 for information security), these are inextricably linked to overall user protection:

• Segregated Management of Customer Assets: Ensuring users' fiat and crypto-assets are kept separate from the CAESP's own funds and are protected in the event of the CAESP's insolvency is a critical safeguard.
• Information Security and Cybersecurity: Protecting user accounts, personal data, and transaction information from unauthorized access, theft, or misuse is a fundamental expectation. This includes robust cybersecurity defenses against hacking and data breaches.

The Complementary Role of Self-Regulatory Organizations (SROs)

In Japan, SROs such as JVCEA and the Japan Cryptoasset Business Association (JCBA) play a significant role in augmenting the legal framework for user protection. They establish more granular operational rules, best practices, and codes of conduct for their member CAESPs. These SRO rules often cover areas such as:

• Advertising Standards: Detailed rules on what can and cannot be said in advertisements, requirements for prominent risk warnings, and prohibitions on misleading claims.
• New Crypto-Asset Listing Reviews: SROs have processes for reviewing new crypto-assets before they can be listed by member exchanges. This review often considers the asset's technical soundness, security, utility, and the background of the project, thereby indirectly protecting users from exposure to potentially problematic or fraudulent tokens.
• Margin Trading Rules: SROs have set limits on leverage ratios for crypto-asset margin trading to mitigate excessive risk-taking by retail users.
• Complaint Resolution Support: SROs may offer additional support or guidance in resolving disputes between users and member CAESPs.

Adherence to SRO rules is typically a condition of membership and is taken seriously by the FSA as an indicator of a CAESP's commitment to industry best practices.

FSA's Supervisory Focus and Enforcement

The FSA actively monitors CAESPs' compliance with user protection obligations through a combination of:

• Reporting Requirements: CAESPs must submit regular reports on their business operations, financial status, and handling of customer assets.
• On-Site Inspections and Off-Site Monitoring: The FSA conducts inspections to assess the adequacy of internal controls, systems, and procedures related to user protection.
• Review of Complaints: The FSA monitors the nature and volume of user complaints received by CAESPs and ADR bodies.

Where deficiencies are found, the FSA has a range of enforcement tools, including issuing:

• Administrative Guidance: Recommending improvements.
• Business Improvement Orders (業務改善命令 - gyōmu kaizen meirei): Legally binding orders requiring specific corrective actions.
• Business Suspension Orders (業務停止命令 - gyōmu teishi meirei): Orders to suspend all or part of the CAESP's operations for a specified period.
• Registration Revocation (登録取消し - tōroku torikeshi): In cases of serious or persistent violations.

Challenges in Realizing User Protection

Despite the comprehensive framework, ensuring effective user protection in the dynamic crypto-asset space presents ongoing challenges:

• Rapid Technological Change: New types of crypto-assets, DeFi applications, and evolving technologies constantly create new risks that regulations must adapt to.
• Information Asymmetry: Users, especially retail investors, often have less information and technical understanding than CAESPs or token issuers.
• Cross-Border Nature: Many crypto-asset activities and service providers operate across borders, making regulation and enforcement complex.
• Inherent Volatility: The high price volatility of many crypto-assets means that users can suffer significant losses even in the absence of misconduct by a CAESP. Clear risk disclosure is vital but may not always prevent such losses.

Conclusion: A Multi-Layered Approach to Safeguarding Users

Japan's regulatory regime for Crypto-Asset Exchange Service Providers demonstrates a strong commitment to user protection. This is achieved through a multi-layered approach that combines mandatory information disclosures, rules for fair and ethical business practices, requirements for robust internal governance and systems within CAESPs, stringent security measures for user assets and data, and active oversight by both the FSA and industry SROs. While challenges remain in this rapidly evolving sector, these comprehensive measures aim to foster greater transparency, mitigate risks, and build a more trustworthy environment for all participants in Japan's crypto-asset market. For CAESPs, adherence to these user protection principles is not just a matter of legal compliance but a cornerstone of building a sustainable and reputable business.
