第一勧業銀行
TKB agreed to merge with Mitsui 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.
