# Japan net bank deposit & feature matrix 2026

## TL;DR

Japan's online-bank market is not one homogeneous category. Operators differ by group ownership, direct-versus-partner distribution, product scope, and public disclosure format. This page therefore records **where each claim can be verified** rather than freezing volatile balances, rates, fees, rankings, or launch assumptions into a long-lived table. Use each bank's current product page for customer terms, its latest disclosure or IR material for balance-sheet figures, and the FSA register for licence status.

## Wiki route

This page sits under [[banking/INDEX|banking index]] as a 2026-vintage deposit-and-feature comparison surface. The segment-level framing lives in [[banking/japan-net-bank-competition-map|Japan net bank competition map]] and [[banking/japan-banking-license-tier-comparison-matrix|Japan banking license tier comparison matrix]]. Specific per-bank pages: [[banking/sony-bank|Sony Bank]], [[banking/ui-bank|UI Bank]], [[banking/gmo-aozora-net-bank|GMO Aozora Net Bank]], [[banking/daiwa-next-bank|Daiwa Next Bank]], [[banking/rakuten-bank|Rakuten Bank]], [[banking/paypay-bank|PayPay Bank]], [[banking/au-jibun-bank|au Jibun Bank]], [[banking/minna-bank-baas-model|Minna Bank BaaS model]], [[banking/mercari-bank|Mercari Bank]], [[banking/mercari-bank-license-stack|Mercari Bank license stack]]. Operating models live in [[banking/japan-baas-operating-models|Japan BaaS operating models]] and [[banking/regional-bank-api-digital-partnership-route|regional bank API digital partnership route]]. Post-megabank context: [[banking/post-megabank-positioning|post-megabank positioning]].

## Why deposit feature comparison matters in 2026

Three structural shifts make a deposit-and-feature comparison especially useful in 2026.

1. **Rate normalisation has restarted deposit competition.** BOJ's exit from negative-rate policy across 2024-2025 returned positive short-rate territory, which broke the multi-year "all deposit rates are zero" simplification. Net banks are again differentiating on tiered rates, FX deposits, and structured deposit products — see [[banking/japan-net-bank-competition-map|Japan net bank competition map]] for the segment-level framing.
2. **Embedded finance via bank API is the new BaaS surface.** The bank API regime under [[fintech/INDEX|fintech]] has matured into mainstream distribution. [[banking/japan-baas-operating-models|Japan BaaS operating models]] documents partner-branch and white-label account architectures. Net banks differ materially in whether they publish bank APIs, white-label account containers, or both.
3. **Mortgage origination has become a primary scale axis for net banks.** [[banking/sony-bank|Sony Bank]], [[banking/au-jibun-bank|au Jibun Bank]], and [[banking/rakuten-bank|Rakuten Bank]] each run sizeable variable-rate mortgage flows. [[finance/japan-acquisition-finance|Japan acquisition finance]] context and [[banking/post-megabank-positioning|post-megabank positioning]] explain why net-bank mortgages now compete head-on with megabank originators in the variable-rate book.

## Bank universe in scope

Eleven banks anchor the comparison:

- **Ecosystem-anchored retail** — [[banking/rakuten-bank|Rakuten Bank]], [[banking/paypay-bank|PayPay Bank]], [[banking/au-jibun-bank|au Jibun Bank]].
- **Securities-adjacent / asset-formation** — [[banking/sony-bank|Sony Bank]], [[banking/daiwa-next-bank|Daiwa Next Bank]], [[regional-banks/sbi-shinsei-bank|SBI Shinsei]] context entries via [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]] (the NEOBANK / mortgage-anchor net bank).
- **Corporate API / SME** — [[banking/gmo-aozora-net-bank|GMO Aozora Net Bank]].
- **BaaS / partner-led** — [[banking/minna-bank-baas-model|Minna Bank]] (Fukuoka FG digital-bank brand), [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]] NEOBANK partner stack.
- **Regional digital** — [[banking/ui-bank|UI Bank]] (Tokyo Kiraboshi FG).
- **Fintech-issued** — [[banking/mercari-bank|Mercari Bank]] (2025-2026 launch).
- **Postal / government-anchored** — [[regional-banks/japan-post-bank|Japan Post Bank]] digital channel (Yucho Direct + Yucho Pay) is included as a digital-channel comparison even though it is not a pure net bank.

The cohort excludes corporate-only digital lenders (e.g. Funds), wallet-only operators ([[card-issuers/paypay-card|PayPay Card]] without the bank entity), and pre-launch projects.

## Core matrix — product evidence map

| Comparison field | What can be published | Required official evidence | Update discipline |
|---|---|---|---|
| Deposits and account counts | Dated point-in-time figure, with the reporting perimeter stated | Latest bank disclosure or group IR table | Never mix bank-only accounts with partner-brand accounts |
| FX deposits / foreign currency | Currencies and product types currently shown | Current bank product page and customer terms | Do not rank breadth without a same-day complete census |

| Debit / credit linkage | Named live card or group linkage | Issuer and bank product pages | Do not infer ownership from branding alone |
| API / BaaS | Published API, partner branch, or named live partnership | Bank developer portal or dated joint announcement | Separate statutory open-banking connectivity from commercial BaaS |
| ATM, transfer, rate, and spread terms | Exact terms only when accompanied by an as-of date | Current fee, rate, and product-condition pages | Treat campaigns and customer tiers as temporary |

## Publication protocol for volatile comparisons

| Field | Minimum evidence | Required label | Publication rule |
|---|---|---|---|
| Deposit balance | Official financial disclosure | Balance-sheet date and unit | Preserve the reporting perimeter and do not round into a ranking |
| Account count | Official KPI disclosure | Measurement date and account definition | State whether partner / BaaS accounts are included |
| Interest rate | Bank rate page or customer terms | Retrieval date, tenor, balance tier, and campaign status | Do not carry a rate into a later review cycle |
| ATM / transfer fee | Official fee schedule | Retrieval date and customer tier | Record conditions for free transactions |
| FX spread | Official live-rate or spread page | Currency pair, channel, and retrieval time | Do not compress multiple currencies into “tight / wide” |
| Partnership | Dated joint announcement from the parties | Announcement date and operating status | Distinguish announced, launched, suspended, and ended |

## Differentiation axes

### Deposit-base comparison

Deposit scale is comparable only after aligning the balance-sheet date, entity perimeter, account definition, and unit. A bank-wide figure must not be compared with a digital-channel subset, and a direct-account count must not be compared with a count that includes partner-brand accounts. This page therefore routes readers to dated disclosures rather than maintaining an approximate league table.

### FX-product depth as differentiation

[[banking/sony-bank|Sony Bank]] occupies the FX-depth corner explicitly. [[banking/au-jibun-bank|au Jibun Bank]] is the closest peer with multi-currency FX deposits and FX margin trading. [[banking/rakuten-bank|Rakuten Bank]] and [[banking/paypay-bank|PayPay Bank]] offer narrower FX product menus. The non-FX banks ([[banking/daiwa-next-bank|Daiwa Next Bank]], [[banking/minna-bank-baas-model|Minna Bank]], [[banking/mercari-bank|Mercari Bank]]) cede the FX-customer segment.

### Mortgage origination as scale lever

Variable-rate mortgages remain the largest single asset class for net banks that have entered the mortgage market. [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]] is the largest net-bank originator. [[banking/sony-bank|Sony Bank]] and [[banking/au-jibun-bank|au Jibun Bank]] follow. [[banking/rakuten-bank|Rakuten Bank]] originates via group structures. [[banking/paypay-bank|PayPay Bank]] and [[banking/daiwa-next-bank|Daiwa Next Bank]] do not anchor mortgages.

### Bank-API publishing posture

Three publishing tiers are observable:

- **Extensive corporate API** — [[banking/gmo-aozora-net-bank|GMO Aozora Net Bank]] is the anchor; explicit corporate-treasury and SaaS-connector API focus.
- **Extensive BaaS / white-label** — [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]] (NEOBANK) and [[banking/minna-bank-baas-model|Minna Bank]] BaaS. These let partner brands publish their own bank-like UX while the bank holds the licence.
- **Standard retail bank API** — most others. Bank API is published for the [[banking/japan-baas-operating-models|electronic payment agency / FA]] regime but the bank does not pursue white-label distribution.

### Embedded-finance partner ecosystem

The embedded-finance partner column reveals which net banks are competing on **distribution surface** versus **direct customer-acquisition**. [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]] partners with JAL, Yamada, T (CCC), and others through NEOBANK; [[banking/minna-bank-baas-model|Minna Bank]] partners with Recruit and others; [[banking/gmo-aozora-net-bank|GMO Aozora Net Bank]] integrates with freee, MoneyForward, payroll SaaS. The ecosystem retail banks ([[banking/rakuten-bank|Rakuten Bank]], [[banking/paypay-bank|PayPay Bank]], [[banking/au-jibun-bank|au Jibun Bank]]) lean on their own group ecosystem rather than third-party partner brands.

## Cluster summary — competitive map by lever

A useful cluster reading:

- **FX + asset-formation cluster** — [[banking/sony-bank|Sony Bank]], [[banking/daiwa-next-bank|Daiwa Next Bank]], [[banking/au-jibun-bank|au Jibun Bank]].
- **Mortgage origination cluster** — [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]], [[banking/sony-bank|Sony Bank]], [[banking/au-jibun-bank|au Jibun Bank]], [[banking/rakuten-bank|Rakuten Bank]].
- **Ecosystem-wallet cluster** — [[banking/rakuten-bank|Rakuten Bank]], [[banking/paypay-bank|PayPay Bank]], [[banking/au-jibun-bank|au Jibun Bank]].
- **BaaS / partner cluster** — [[banking/sumishin-sbi-net-bank|Sumishin SBI Net Bank]] NEOBANK, [[banking/minna-bank-baas-model|Minna Bank]].
- **Corporate / SME API cluster** — [[banking/gmo-aozora-net-bank|GMO Aozora Net Bank]].
- **Regional digital cluster** — [[banking/ui-bank|UI Bank]], [[regional-banks/01-bank|01 Bank]] (peer reference).
- **Fintech-issued cluster** — [[banking/mercari-bank|Mercari Bank]].
- **Postal anchor** — [[regional-banks/japan-post-bank|Japan Post Bank]].

## Source caveats

1. **Balance and account figures** require a reporting date, unit, and entity perimeter; use the latest bank disclosure rather than an estimate copied from this page.
2. **Account definitions** may or may not include BaaS-partner accounts; preserve the issuer's definition.
3. **Fees, rates, campaigns, and FX spreads** change frequently; use current customer terms and record the retrieval date.
4. **Product availability** can change by customer segment or channel; absence from this matrix is not evidence that a bank does not offer the product.
5. **Partnership status** must be taken from dated announcements by the parties and must distinguish announcement from launch.
6. **Licence status** must be checked against the current FSA register.

## Research checklist

When extending this matrix:

1. Pull the bank IR page or quarterly disclosure for deposit balance and account count.
2. Cross-check via FSA Bank Information Disclosure aggregate.
3. Read the bank's API developer portal for bank-API depth and partner list.
4. Use the [[banking/japan-baas-operating-models|BaaS operating models]] page to classify the bank's BaaS posture.
5. Use [[banking/quick-deposit-four-methods|quick deposit four methods]] for payment-channel context.
6. Use [[banking/japan-banking-license-tier-comparison-matrix|banking license tier comparison]] to confirm licence category.
