History
Like most modern Japanese institutions, the Bank of Japan was fou ...
in 1882. In ensuing decades, the
Mitsui family took over numerous government industrial plants to form a major ''
zaibatsu'' conglomerate, with the bank as one of its core businesses. Mitsui Bank reorganized as an unlimited partnership in 1893, and as a limited company (capital stock: ¥20 million) in 1909.
World War II
World War II led Mitsui Bank to distance itself from the Mitsui ''zaibatsu'' beginning around 1937, as the bank's large balance of loans to munitions manufacturers made it vulnerable to failure should a recession occur after the war. The solution found by Mitsui's chairman was to merge the bank with the
Dai-Ichi Bank, creating a much larger institution outside the Mitsui family's control.
In April 1943, Mitsui Bank merged with Dai-Ichi to form
Teikoku Bank ("Imperial Bank").
Teikoku almost immediately found itself short of funds, and for the remainder of the war, mainly provided short-term financing, with long-term financing for its munitions manufacturing customers mostly provided by the
Industrial Bank of Japan.
Dai-Ichi and Mitsui had very different corporate cultures which led to friction between the two; the two banks never completely integrated, and in October 1948, Dai-Ichi Bank separated from Teikoku Bank.

Teikoku Bank listed its shares on the Tokyo and Osaka stock exchanges in May 1949 and changed its name back to Mitsui Bank in January 1954.

Mitsui established The Mitsui Bank of California in Los Angeles in 1974, and acquired Manufacturers Bank in 1981, merging the two later that year to form Mitsui Manufacturers Bank (renamed Manufacturers Bank in 1992).
Mitsui Bank agreed to merge with
Taiyo Kobe Bank in 1989. At the time (in the midst of the
Japanese asset price bubble), the merger was to create the second largest bank in the world behind
Dai-Ichi Kangyo Bank. While TKB had a strong base of individual and small business customers, Mitsui had a complementary base of larger institutional clients. The merger was aimed at leveraging these synergies, as well as providing stronger competition against European banks, which were expected to consolidate following a deregulation in 1992.
