1. Identity and ownership

Sources: the identity, ownership route, and license category are supported by Sony Bank’s company profile, Sony’s official partial-spin-off record, and the FSA workbook. The spin-off changed Sony Group’s ownership of Sony Financial Group; it did not make Sony Bank itself a listed entity. ^[Sources: https://moneykit.net/visitor/co/; https://www.sony.com/en/SonyInfo/IR/library/SFG_pso/; https://www.fsa.go.jp/menkyo/menkyoj/ginkou.xlsx.]

Where Sony Bank sits inside the parent

Sony Group Corporation (TSE 6758, ultimate parent)
  └── Sony Financial Group (re-consolidated 2020 via TOB; re-listed on TSE Prime 2025-09-29 via partial spin-off, Sony Group retains ~20%)
        ├── Sony Bank Incorporated (the entry on this page)
        ├── Sony Life Insurance
        ├── Sony Insurance (P&C)
        └── Other financial subsidiaries

Sony FG was previously listed; in 2020 Sony Group launched a TOB and made it a wholly owned subsidiary. Sony’s official partial-spin-off record states that Sony FG listed on the TSE Prime market on 2025-09-29, slightly more than 80% of its shares were distributed in kind to Sony shareholders, and Sony retained slightly less than 20%. Sony FG was deconsolidated and became an equity-method affiliate effective 2025-10-01. Sony Bank itself remains a non-listed operating bank under Sony FG; this entry does not use an unsourced opening-price figure to infer its stake economics. ^[Source: https://www.sony.com/en/SonyInfo/IR/library/SFG_pso/.]

Multi-currency deposit + FX core

Sony Bank’s foreign-currency deposit product is its most distinctive feature relative to the broader net bank universe:

Sources: this table records disclosed product scope; it does not claim peer price leadership or observed customer acquisition by segment. ^[Sources: https://moneykit.net/visitor/fx/; https://moneykit.net/visitor/sbw/; https://www.dic.go.jp/yokinsha/page_000134.html.]

Investment-product distribution

The MoneyKit platform distributes 投信 (investment trusts) and supports securities-account adjacencies. Compared with SSNB’s deep linkage to SBI Securities, or au Jibun Bank’s linkage to au Kabucom, Sony Bank’s securities linkage is comparatively thinner — but the FX strength complements 外貨投信 distribution.

Card and payment adjacencies

Where Sony Bank competes

Sources: Sony Bank’s official pages substantiate its own product set. They do not, by themselves, establish leadership or relative depth across peers, so this matrix is a comparison protocol. ^[Sources: https://moneykit.net/; https://moneykit.net/visitor/fx/; https://moneykit.net/visitor/sbw/; https://moneykit.net/visitor/co/disc.html.]

Customer segmentation

Public product design suggests research hypotheses around overseas use, asset formation, and mortgages. These are not published customer-mix measurements. A customer-segmentation statement should be added only when Sony Bank discloses a dated survey, account cohort, or product-usage distribution.

4. KPI shape and franchise scale

Public Sony Bank disclosure (the 「ディスクロージャー誌」 series and quarterly financial results) shows a multi-trillion-yen deposit base — total deposits of ¥4,536.9 billion as of 2025-09-30 (JPY ¥3,800.6bn + foreign-currency ¥736.2bn) — alongside a growing customer count and a meaningful mortgage book. Granular point-in-time KPIs (account count, mortgage outstanding, ROE) belong to the periodic disclosure cycle; this page tracks the shape of the franchise rather than running every number.

Pattern across recent disclosure cycles

5. Regulatory boundary

Sources: this summary should be read with the FSA license register, the bank’s legal/product disclosures, and Deposit Insurance Corporation guidance; it is not a substitute for the underlying rules. ^[Sources: https://www.fsa.go.jp/menkyo/menkyoj/ginkou.xlsx; https://moneykit.net/visitor/co/disc.html; https://www.dic.go.jp/yokinsha/page_000134.html.]
