Mizuho Bank, Ltd. (株式会社みずほ銀行, Kabushiki-gaisha Mizuho Ginkō) was established on April 1, 2002 by the merger of Dai-Ichi Kangyo Bank with the retail operations of Fuji Bank and the Industrial Bank of Japan. It is the core retail banking unit of Mizuho Financial Group, which is the second-largest financial services company in Japan and one of the three so-called Japanese 'megabanks' (along with Mitsubishi UFJ Financial Group and Sumitomo Mitsui Financial Group). Its headquarters are located in the Uchisaiwaicho district of Chiyoda, Tokyo.

Mizuho Bank has 515 branches and over 11,000 ATMs, and is the only bank to have branches in every prefecture in Japan. It serves over 26 million Japanese households and 90,000 SME customers. Mizuho Bank provides financial products and services for individuals, local governments, mid-sized and small enterprises and other domestic companies among other types of customers.

In the merger of the three banks, Dai-Ichi Kangyo was renamed Mizuho Bank and inherited the group's individual, small business and local/regional government services, while institutional banking services were consolidated into Fuji Bank, which was renamed Mizuho Corporate Bank. The two banks were initially consolidated under a holding company, Mizuho Holdings. On October 1, 2005 they were transferred to a new holding vehicle, Mizuho Financial Group.

Mizuho Financial Group is a bank holding company which operates and manages its banks, long-term credit banks, specialized securities companies and other companies which the Company may own by law as its subsidiaries, and engages in business appertaining to the management and operation of such companies. Mizuho Bank committed to ensure the interests of the customers are protected at any costs, fulfill the responsibilities and make a positive contribution to the communities and society in Japan.
 

In Japan, the Financial Services Agency (金融庁, Kin'yūchō) is responsible for overseeing banking services in order to ensure the stability of the financial system of Japan. Bank of Japan (BOJ) is not a regulatory authority under the Banking Act, but it conducts on-site examinations in order to maintain a safe and sound financial system. These examinations are based on bilateral agreements between the BOJ and financial institutions that have current accounts with it under the Bank of Japan Act.
