2026-02-03Head-office relocation（Otemachi Building FINOLAB → Marunouchi Kitaguchi Building 9F）— the legal entity persists / FSA registration continues

After the 2023-02 service halt, Coinbase 株式会社 has remained in a dormant state.

  • The FSA crypto-asset-exchange-business registration（第00028号）had not been deregistered as of 2026-04 , and the legal entity also persists
  • It has withdrawn from JVCEA（absent from the member roster as of 2026-05 ）
  • No public announcement regarding the parent（Coinbase Global）re-entering / resuming the business（as of 2026-05 ）
  • The head-office-address change（2026-02-03）is seen as minimal legal handling to maintain the legal entity

Industry positioning: this company’s case, alongside Kraken Japan（announced withdrawal 2023-01 ）, is often cited as a “pattern of foreign-affiliated exchanges withdrawing from the Japanese market”（for the background, see Domestic Crypto Asset Exchange M&A and Consolidation History (2018-2026) and Japan domestic VASP parent-company / shareholder-structure map; as contrasting examples, the continuing foreign-affiliated BitTrade / Binance Japan）. The withdrawal reasons cited at the time were the following 3 points:

  1. The strictness of the regulatory environment（KYC / AML compliance cost, the complexity of FSA screening）
  2. The 2022年 crypto-asset-market downturn and high customer-acquisition cost
  3. The parent’s global business contraction（2023年 layoffs）
  • Brian Armstrong: founder / CEO of Coinbase Global. Announced company-wide cost reductions in 2023-01-10
  • Nana Murugesan（Coinbase business-development / international-division executive）: referred to a review of the Japan business in a 2023-01-12 Bloomberg interview
  • Representative director(s), etc., of the Japan entity: no public information（cannot be confirmed as of 2026-05 due to the disappearance of the official site）
