GMO financial ecosystem linkage

• GMO Payment Gateway (payment processing) → potential for expansion into corporate crypto-asset payments
• GMO Click Securities (online securities / FX) → a customer cross-sell base
• GMO Aozora Net Bank (online bank) → deposit / withdrawal flow line
• GMO Internet itself (infrastructure / cybersecurity) → an exchange security foundation

Competitive positioning

The following table is scoped to public primary sources (coin.z.com, fsa.go.jp). It restates licence / structure / product boundaries from those materials and does not invent market share, ranking, or unstated numerical claims. ^↗

GMO Coin’s differentiation: ① Director-General of the Kanto Local Finance Bureau 第 00006 号 (the credibility of being the most senior), ② early entry into leveraged trading in the industry / a main revenue source, ③ the infrastructure / KYC / customer-support base of the GMO financial group, ④ continued expansion of the number of tradable currencies.

Web3 / DeFi expansion

• A history of stablecoin (GYEN / ZUSD) issuance at GMO Trust (a US subsidiary)
• Division of functions with GMO Web3 (the GMO Internet Group’s Web3 subsidiary)
• Entry into the Web3 field, such as the NFT market, is more cautious than competitors (Coincheck NFT, etc.)

5. Regulation / policy

• Jurisdiction: FSA / Kanto Local Finance Bureau
• Registration: Crypto-asset exchange operator (Payment Services Act Article 63 -2) / Director-General of the Kanto Local Finance Bureau 第 00006 号
• Self-regulation: JVCEA (Japan Virtual and Crypto assets Exchange Association) Type 1 member ── tradable-currency screening / unified AML/KYC standards
• Derivatives: FIEA Type 1 Financial Instruments Business (crypto-asset derivatives trading; since the 2019-05 amendment)
• Policy topics from 2024:
  • Stablecoin regime (amended Payment Services Act, in force 2023-06 ) → GMO has advance know-how via its US subsidiary
  • Tax system: crypto-asset gains/losses taxed as miscellaneous income under progressive taxation → request for a shift to separate self-assessment taxation (common across the industry)
  • Taxation on year-end fair-value valuation of crypto-assets held by corporations → amendment in progress
  • Speeding up of JVCEA tradable-currency screening (a common industry issue)

[!info] 検証状況 confidence: likely (public information only, based on Wikipedia + FSA registration + JVCEA public materials, 2026-05-19 verified). The number of tradable currencies / details of the organizational structure vary, so the latest figures should be checked against the GMO Coin official site / GMO FHD IR. The business continuity of the US subsidiary GMO Trust (GYEN / ZUSD) requires separate confirmation.
