AML Obligations

  • VASPs (including custodial wallet providers) must register as a Crypto-Asset Exchange Service Provider (CAESP) with the FSA under the Payment Services Act
  • Comprehensive KYC procedures required for all customers (aligned with FATF recommendations)
  • Transaction monitoring and suspicious activity reporting (SAR) obligations to the FSA
  • Travel Rule compliance expected (FATF-aligned rules apply)
  • Ongoing AML/CFT compliance programs required with internal controls and audits

Key Restrictions

  • Must register as a CAESP (Crypto-Asset Exchange Service Provider) with the FSA — the custodial wallet SaaS model falls under 'management of crypto-assets for others'
  • Minimum capital of JPY 10M (~$70K USD) required
  • Must maintain positive net assets at all times
  • Mandatory segregation of customer assets (trust account or equivalent required)
  • 100% cold storage recommended for customer assets
  • JVCEA membership is mandatory (self-regulatory organization)
  • Multi-signature wallets, penetration testing, and internal audits required by regulation
  • Token listings must be pre-screened by JVCEA
  • Application timeline of 6-18 months for CAESP registration

Key Risks

  • FSA has enforcement power to issue administrative orders, impose penalties, and revoke licenses — high regulatory scrutiny
  • The boundary between the custodial SaaS provider's AML obligations and the white-label client's obligations is not explicitly delineated in the regulatory framework — both likely need separate CAESP registrations
  • Stablecoin Law (June 2023) creates separate requirements for stablecoin custody — issuance/mediation may require additional fund transfer service provider registration
  • 6-18 month licensing timeline creates operational delay risk for market entry
  • Tax treatment uncertainty — National Tax Agency (NTA) has its own enforcement priorities for crypto

Evidence

This verdict synthesizes the following facts. Each fact links to its primary source(s).

licensing 90% confidence

The FSA (with Local Finance Bureaus) registers and supervises crypto-asset exchange service providers (PSA Art. 63-2) and EPI exchange service providers (Art. 62-3), and drafted Law No. 64 of 2026, which moves crypto-asset trading to the FIEA; that law’s crypto provisions are not yet in force.

licensing 88% confidence

JVCEA is the certified association under PSA Art. 87, but membership is not mandatory: an applicant may instead adopt equivalent internal rules (PSA Art. 63-5(1)(vi)). New tokens require prior notification to the JVCEA, which may object (Rule on Handling of Crypto-Assets Art. 5); it also audits and sanctions members.

licensing 90% confidence

The Payment Services Act (Act No. 59 of 2009) crypto regime of registration, customer verification and asset segregation took effect in April 2017; a 2019 amendment in force May 2020 made changes to handled crypto-assets subject to prior notice, added advertising rules and required user crypto to be held in cold wallets in principle.

licensing 90% confidence

Crypto-asset exchange service providers register under PSA Art. 63-2 with capital of at least ¥10 million and non-negative net assets (CAESP Ordinance Art. 9). Cold storage is mandatory except a 5% hot-wallet cap (Art. 27(2)). JVCEA membership is optional if equivalent internal rules are adopted (PSA Art. 63-5(1)(vi)); new tokens need prior notice to the JVCEA.

licensing 90% confidence

Custody of crypto-assets for others (PSA Art. 2(15)(iv)) is crypto-asset exchange business requiring Art. 63-2 registration. User money must be entrusted to a trust company (Art. 63-11(1)); user crypto must be segregated and held by the cold method, with hot-wallet holdings capped at 5% (CAESP Ordinance Art. 27), and segregation is audited by a CPA or audit firm (Art. 63-11(3)).

licensing 93% confidence

Crypto-asset exchange business under Payment Services Act Art. 2(15) covers buying, selling or exchanging crypto-assets, intermediating, brokering or acting as agent for these, managing user money in connection with them, and custody of crypto-assets for others; it requires registration with the Prime Minister (Art. 63-2), not a licence.

licensing 90% confidence

Crypto-asset exchange service providers must hold users' crypto-assets separately from their own so each user's holding is immediately identifiable (CAESP Ordinance Art. 27(1)), keep them in cold storage except a hot-wallet portion capped at 5%, and hold their own crypto of the same kind and amount against hot-wallet user crypto (PSA Art. 63-11-2).

licensing 20% confidence

Robust Security Measures: Strict requirements for cybersecurity, including multi-signature wallets, penetration testing, and internal audits.

licensing 92% confidence

Crypto-asset exchange service providers are specified business operators under the Act on Prevention of Transfer of Criminal Proceeds (Act No. 22 of 2007, Art. 2(2)(xxxii)); they must conduct customer verification (Art. 4), file suspicious transaction reports (Art. 8), and notify originator and beneficiary information to the receiving provider on customer crypto transfers to other providers (Art. 10-5).
