# Japan net bank competition map

## Overview

Japan net-bank competition includes several public operating models: ecosystem retail banks, full-banking BaaS / white-label banks, SME / corporate API banks, securities / asset-formation banks, and regional-group digital banks. The FSA bank list provides the legal universe. Public comparison fields include customer acquisition channel, parent ecosystem, deposit franchise, lending mix, BaaS depth, securities / payments adjacency, and primary-account conversion.

## Competitive Segments

| Segment | Main examples | Public operating role |
|---|---|---|
| Ecosystem retail bank | [[banking/rakuten-bank|Rakuten Bank]], [[banking/paypay-bank|PayPay Bank]], [[banking/au-jibun-bank|au Jibun Bank]] | Convert commerce / telecom / payment frequency into bank accounts, deposits, cards, loans, and salary-account use. |
| Full-banking BaaS / white-label | [[regional-banks/ssnb|SSNB]] NEOBANK, [[banking/minna-bank-baas-model|Minna Bank]] partner branches | Let non-bank brands distribute bank accounts and banking features through partner UX. |
| Corporate API / SME bank | [[payment-firms/gmo-aozora-net|GMO Aozora Net Bank]] | Serve startups, SMEs, SaaS, accounting, payment, and API-driven treasury workflows. |
| Asset-formation / securities-adjacent bank | [[regional-banks/sony-bank|Sony Bank]], [[regional-banks/daiwa-next-bank|Daiwa Next Bank]], [[banking/au-jibun-bank|au Jibun Bank]] | Link deposits with FX, investment, mortgages, securities, and household asset-building. |

## Comparison Axes

| Axis | What to collect | Why |
|---|---|---|
| Parent ecosystem | Commerce, payment, telecom, securities, trust bank, regional bank, or independent group | Explains customer acquisition and cross-sell cost. |
| Account scale | Date-stamped account count or customer base | Useful only if dated; account count can move quickly. |
| Deposit franchise | Deposit balance, salary account, settlement account, or promotional balance | Determines funding stability and primary-bank conversion. |
| Lending mix | Mortgage, card loan, personal loan, business loan, securities collateral, or no meaningful loan book | Drives ROA, credit risk, and capital use. |
| BaaS / API depth | Partner branches, API services, white-label accounts, corporate API | Separates consumer app banks from platform infrastructure banks. |
| Securities / payment adjacency | Brokerage, wallet, card, QR payment, quick deposit, FX | Explains daily frequency and revenue beyond net interest margin. |
| Regulatory stack | Bank license, bank agent, electronic payment agency, funds transfer, prepaid, FIEA | Prevents UX from being confused with legal function. |

Sources: the comparison axes are a collection protocol. Legal bank identity comes from the FSA workbook, while ownership, products, and operating metrics must come from each bank's dated official disclosure; no ranking is implied by the table. ^[Sources: https://www.fsa.go.jp/menkyo/menkyoj/ginkou.xlsx; https://www.paypay-bank.co.jp/company/about/; https://www.jibunbank.co.jp/corporate/performance/; https://www.netbk.co.jp/contents/company/about/; https://gmo-aozora.com/company/outline.html; https://sonybank.jp/corporate/aboutus/profile.html; https://www.uibank.co.jp/info/.]

## Model Notes

### Ecosystem Retail

[[banking/rakuten-bank|Rakuten Bank]], [[banking/paypay-bank|PayPay Bank]], and [[banking/au-jibun-bank|au Jibun Bank]] are ecosystem banks. Their public distribution surfaces include commerce, telecom, card, wallet, points, securities, and everyday payment behavior. Primary-account conversion fields include salary deposits, recurring payments, mortgages, cards, and high-frequency transfers.

### BaaS / White-Label Banking

[[regional-banks/ssnb|SSNB]] operates the NEOBANK partner-led BaaS model. [[banking/minna-bank-baas-model|Minna Bank]] discloses partner-branch and API-provided banking models. These are distribution architectures where the customer journey may be controlled by a partner brand while the bank account remains with the bank.

### SME / Corporate API

[[payment-firms/gmo-aozora-net|GMO Aozora Net Bank]] is the corporate API / SME banking anchor. Its public product fields include business-account opening, transfers, accounting, payroll, SaaS, and platform settlement flows.

### Asset-Formation Specialists

[[regional-banks/sony-bank|Sony Bank]] and [[banking/au-jibun-bank|au Jibun Bank]] show how a net bank can compete through mortgages, FX, securities adjacency, and household asset-building rather than pure payment frequency. Compare them with [[securities/japan-online-brokerage-competition|online brokerage competition]] when the customer journey moves from deposits to investment products.

### Regional Digital Banks

[[regional-banks/ui-bank|UI Bank]] and [[regional-banks/01-bank|01 Bank]] are regional-group digital-bank examples. Public comparison fields include digital deposit channel, branch-footprint extension, customer segment, and group-bank linkage.

## Source Fields

1. Account-count metric and source date.
2. Parent-group, bank-only, account-only, or active-customer data category.
3. BaaS accounts and primary retail bank accounts where separately disclosed.
4. Deposit scale and lending profitability.
5. API / bank-agent category linked to [[banking/japan-baas-operating-models|BaaS operating models]] and [[payments/japan-bank-api-payment-agency-route|bank API payment agency route]].
6. Securities flows linked to [[securities/INDEX|securities index]] and quick-deposit routes.
