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.
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.
Postwar era

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 Bank merged with Toto Bank in April 1968.

), 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.
