This entry sits under exchanges index. Read it against Japan crypto audit-firm landscape — Big4 + Grant Thornton Taiyo + BDO Sanyu crypto-practice comparison for peer / contrast context and FSA crypto-asset exchange registration system — number system / Local Finance Bureau jurisdiction / registration requirements for the broader system / regulatory boundary.

Overview

For Japanese domestic VASPs, Web3 operators, and stablecoin issuers, a structure has become established in which legal advice is received primarily from 5 large urban full-service law firms. Because this is a composite area spanning the Payment Services Act + the amended Financial Instruments and Exchange Act (FIEA) + the Act on Prevention of Transfer of Criminal Proceeds + tax law + FIEA + the Act on the Protection of Personal Information + the Civil Code + the Companies Act + overseas securities law (US SEC / EU MiCA), large law firms capable of multi-practice coverage are preferred. Anderson Mori Tomotsune (AMT) / Nishimura & Asahi / Mori Hamada Matsumoto (MHM) / TMI Associates / BCLP (Bryan Cave Leighton Paisner) form the “crypto-legal Big 5.”

  • Kataoka & Partners — FinTech-specialized, with deep coverage of crypto-asset regulation
  • so-Law + Atsumi & Sakai — for mid-tier crypto operators

Major business areas

  1. VASP registration applications · change notifications: FSA crypto-asset exchange registration system — number system / Local Finance Bureau jurisdiction / registration requirements acquisition · renewal · adding newly handled currencies
  2. Token issuance / IEO legal work: JVCEA WhiteList screening response · securities-nature determination
  3. Stablecoin regulatory response: designing specified-trust-beneficiary-right schemes after the 2023-06 amended Payment Services Act took effect
  4. Travel Rule implementation: → Domestic VASP Act on Prevention of Transfer of Criminal Proceeds + FATF Travel Rule Domestic Implementation (2023-)
  5. M&A / business transfer: VASP subsidiarization, foreign-capital-withdrawal deals (FTX Japan → bitFlyer HD, etc.)
  6. Overseas regulatory response: parallel advice with MiCA · SEC · MAS · FCA
  7. Hacking · outflow incident response: criminal complaints · Global crypto-asset forensics-vendor layer — Chainalysis / Elliptic / TRM / Crystal comparison coordination · OFAC-sanctions response
  8. Token-taxation advice: Domestic crypto-asset taxation detail — miscellaneous income vs separate self-assessment + individual vs corporate × corporate accounting

The three pillars of audit + legal + forensics

The combination of these forms the compliance framework of domestic VASPs.
