Mizuho was established originally as Mizuho Holdings, Inc. by the merger of Dai-Ichi Kangyo Bank, Fuji Bank, and the Industrial Bank of Japan in 2000. The earliest history of the companies that formed the Mizuho group was Yasuda-ya, which was founded as a private company in 1864. Then in 1872 the Dai-Ichi Bank, Ltd. was established as the first bank in Japan to be established under the nation's newly minted National Bank Act of 1872. In 1897 the Nippon Kangyo Bank, Ltd. and the Industrial Bank of Japan, Limited were next established as governmental institutions. In 1912 Yasuda-ya was incorporated and renamed Yasuda Bank, in a process where Yasuda absorbed the assets and business of seventeen different Japanese banking institutions.
