Mikogi Bank

Mikogi Bank, Ltd. (株式会社光菱国際銀行, Kabushikigaisha Mitsuhishi Kokusai Ginkō) is the largest bank in Yamatai. It was established on January 1, 2006, following the merger of the International Bank of Niihama, Ltd. and Mitsuhishi Bank Ltd. Mikogi is one of the three so-called Yamataian "megabanks" (along with Shinomiya-Sukimoto and Central Heian Banking Corporation).

The bank serves as the core retail, corporate, and investment banking arm of the Mitsuhishi Financial Group, a part of the Mitsuhishi Group. Its traditional client base is made up of Yamataian corporates, but overseas corporate lending increased 35% in the nine months to December 31, 2011. The bank has steadily increased its tier 1 capital ratios from 7.76% in 2009 to 13.04% as reported in February 2012, and its credit ratings have been unaffected by developments in Amphia.

As of June 23, 2019, Mikogi was ranked as the largest bank in Yamatai and the fourth largest in the world.

The bank's head office is in Chūō, Niihama, and it has 772 other offices in Yamatai and 76 offices overseas.
