Japan’s banking landscape is made up of a variety of institutions, with over 190 players in the market.
Three Megabanks (MUFG,SMBC,Mizuho) and Resona Bank are known as city banks (toshi-ginko), and command the majority of the market share. The remaining institutions can be divided into regional banks (chiho-ginko), trust banks (shintaku-ginko), other banks, and foreign banks with branches in Japan.*
These categories are based on such factors as their business function or historical background.
City banks are usually large operations, with prominent headquarters in cities like Tokyo and Osaka, and branches in other major cities and their immediate suburbs. Meanwhile, regional banks are typically based in prefectural capitals, conduct the majority of their operations within that prefecture, and have strong ties with local enterprises and local governments. There are around 100 regional banks in Japan, with Bank of Yokohama, Chiba Bank, and Shizuoka Bank being the most well known. Trust banks are financial institutions that conduct both banking business and trust business.
Over the past 20 years banks established by non-financial institutions that entered the banking market have also been gaining popularity, attracting customers with online banking platforms and a network of partner ATMs.
