Model Notes

Ecosystem Retail

Rakuten Bank, PayPay Bank, and 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

SSNB operates the NEOBANK partner-led 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

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

Sony Bank and 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 online brokerage competition when the customer journey moves from deposits to investment products.

Regional Digital Banks

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