GMO Aozora Net Bank

Wiki route

This entry sits under payment-firms INDEX. Read it against SBI Sumishin Net Bank → Docomo SMTB Net Bank for peer / contrast context and banking index for the broader system / regulatory boundary.

TL;DR

A net bank anchored on a corporate-focused BaaS (Banking as a Service) axis. It developed from the former Aozora Trust Bank, originally a wholly owned Aozora Bank subsidiary, and was renamed and converted into a net bank in 2018-07 after preparations for the GMO joint venture. The official company profile reports share ownership of Aozora Bank 50.00% / GMO Internet Group 25.00% / GMO Financial Holdings 25.00% and voting rights of Aozora Bank 85.12% / the two GMO companies 7.43% each as of 2026-02-20. The former statement that GMO acquired a voting majority was therefore incorrect; Aozora Bank is the current voting-control shareholder. Unlike retail-focused Rakuten Bank, PayPay Bank, and SBI Sumishin Net Bank, it centers corporate accounts for freelancers, startups, and fintech integrations plus API connectivity. Its representative services are Anshin Wide and Bank API for Developers, supported by partnerships with freee, Money Forward, Square, Stripe, and other fintechs. ^•

Background: GMO invested in 2016-05, and the bank converted to the net-bank model in 2018-07. Under the 2016 shareholders’ agreement, class shares held by Aozora Bank were transferred to GMO Financial Holdings in 2023.

Differentiation on the corporate-BaaS axis

• Changing the battlefield from individual-focused net banks (Rakuten Bank / PayPay Bank / sbi-sumishin-net / au Jibun Bank, etc.): rather than competing on individual-account count, it concentrates on responding to corporate BaaS and the API economy
• “Anshin Wide” (a corporate business loan) leverages GMO Payment Gateway’s settlement data for credit assessment → a textbook case of group synergy
• The target is the layer of “SMEs / sole proprietors who already use accounting SaaS / settlement SaaS / cloud ERP” — the standard position of a fintech-linked account

Synergy with parent GMO

• Mutual customer routing with GMO Payment Gateway (settlement) / gmo-coin (crypto assets) / GMO Click Securities (securities, FX)
• The banking layer of the entire GMO group’s “internet financial economic zone” (settlement + securities + crypto assets + banking)
• Smaller in scale compared with the economic zones of Rakuten / PayPay / SBI, but a position clearly committed to the corporate / freelancer layer

API / Open Banking strategy

• “Bank API for Developers”: developing the opening-up of APIs for balance inquiry, transfer, account opening, etc., for fintech developers
• Directly connected to accounting clouds such as freee / Money Forward → receipts and payments are automatically recorded
• Also connected to overseas payment fintechs such as Stripe / Square → supporting cross-border settlement
• Capturing the segment difference of “individual fintech is settlement-centered” vs “corporate fintech is accounting / expense / credit-centered”

4. Regulation & policy

• Supervisor: Financial Services Agency (FSA)
• Business type: a bank under the Banking Act (ordinary bank)
• Deposit insurance: member of the Deposit Insurance Corporation
• API regulation: the Open API provision obligation based on the amended Banking Act (2017) → “Bank API for Developers” is an institutional extension thereof
• Connection with funds-transfer business / virtual-currency business: the integration of multiple business-law licenses through linkage with gmo-coin within the GMO group or with GMO Payment Gateway is an issue
• Anti-money-laundering regulation: tightening of identity verification / beneficial-owner verification for corporate account-opening (from 2023, response to the FATF 4 th-round review)
