City bank (Japan)

A city bank is a Japanese term (都市銀行 = "Toshi ginkō" or 都銀 = "Togin") for one of the several mega-banks, with their head offices in Tokyo or Osaka, Japan's two largest cities. These banks have wide networks of branches in major cities all over Japan. There are five such banks: MUFG Bank, Sumitomo Mitsui Bank, Mizuho Bank, and two Resona Banks.

The city bank is used in contrast to the regional bank (地方銀行 ="Chihō ginkō" or 地銀 = "Chigin") with its head office in the capital city of each of the 47 prefectures. They mainly serve their prefectural customers.
