GMO Aozora Net Bank

TL;DR

A net bank anchored on a corporate-focused BaaS (Banking as a Service) axis. Based on the former Aozora Trust Bank (a aozora-bank subsidiary), the GMO Internet Group acquired a majority of voting rights in 2018-07 , renaming it and converting it into a net bank. After the reorganization of classes of shares, the shareholder composition is, on a common-stock (shareholding) ratio basis, Aozora Bank 50.00% / GMO Internet Group 25.00% / GMO Financial Holdings 25.00%, while on a voting-rights ratio basis, Aozora Bank 85.12% / GMO’s two companies 7.43% each (as of 2026-02-20; because part of Aozora’s holdings are voting-rights-restricted class shares, the shareholding ratio and the voting-rights ratio diverge). Unlike Rakuten Bank, PayPay Bank, and SBI Sumishin Net Bank, which emphasize individuals, it places at its core corporate accounts linked to freelancers, startups, and fintech, plus API connectivity. Its representative services are “Anshin Wide” (a business loan for corporations) and “Bank API for Developers.” It has built its position through strategic partnerships with fintechs such as freee, Money Forward, Square, and Stripe.

2. Business segment map

Segment	Main business	Features
Corporate accounts	Freelancer / sole-proprietor / startup accounts	Online-completed account-opening procedures, same-day-opening support; strong in the fintech layer
Corporate loans	Anshin Wide (unsecured business loan)	AI credit model + GMO PG settlement-data linkage
API / BaaS	Bank API for Developers	For corporations / fintech (opening up APIs for balance inquiry, transfer, account opening, etc.)
Partner linkage	freee / Money Forward / Square / Stripe / Wise, etc.	Accounts directly connected to accounting / settlement SaaS
Individual accounts	For the freelancer layer / side-job layer	Avoids head-on confrontation with individual-focused net banks (Rakuten / PayPay / Sumishin SBI, etc.)
Crypto-asset linkage	gmo-coin (sibling company)	Synergy within the GMO group
Settlement linkage	GMO Payment Gateway (sibling company, TSE PRIME 3769)	Settlement processing / merchant-data linkage

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)
