Effort
A few months

Many Japan Post Bank customers still use traditional passbooks, which are inconvenient for modern mobile-first users. Build a banking app that integrates digital passbook features with modern mobile banking conveniences. The bank would pay to reduce branch traffic and modernize customer experience. Start with core features like balance checking, transaction history, and digital passbook viewing. The biggest risk is competing with Japan Post Bank's own app.
