Japan
Banking sector profile — Asia-Pacific
Data as of September 2026 • TGB Intelligence Unit
Structure and performance
Japan's banking system combines three global megabank groups with a large, fragmented regional sector. Domestically licensed banks held ¥1,508.5tn of assets at end-July 2026, of which city banks accounted for about half. MUFG, Sumitomo Mitsui Financial Group and Mizuho are all global systemically important banks; the next tier comprises Japan Post Bank, the agricultural co-operative apex Norinchukin, trust bank groups and Resona. The regional tier comprised 97 banks at end-March 2026, many serving shrinking local economies, and 247 shinkin banks sit beneath them.
