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 Bank merged with Toto Bank in April 1968. Around 1960, Mitsui Bank and its general trading company partner Mitsui & Co. formed a horizontal keiretsu alliance between other companies descended from the Mitsui conglomerate, including Toyota, Toshiba, Toyo Menka Kaisha, Ishikawajima-Harima Heavy Industries, Showa Aircraft and Oji Paper. 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. The TKB-Mitsui merger, agreed in end of 1989 during the height of the Japanese asset price bubble, was to create the second largest bank in the world behind Dai-Ichi Kangyo Bank. While TKB had a large base of individual and small business customers, Mitsui had a complementary base of larger institutional Clients. The Sakura Bank name was adopted 3 years later in April 1992. 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. Sakura became a major corporate and retail bank in the Greater Tokyo Area during the 1990s and was the largest retail bank in Japan by several measures, including housing loan and investment trust sales. However, Sakura incurred massive bad loan write-offs in 1998 and approached one of its major corporate customers, Toyota, for financial support, which was rejected. Sakura led the consortium that established Japan Net Bank, an online
