Wiki route

This entry sits under megabanks INDEX (its domain route). Read it against MUFG Bank for peer / contrast (another 都市銀行 megabank operating company), and against the FSA for the supervisory / regulatory boundary. The group / parent view lives on Mizuho FG (Mizuho FG); the trust and securities siblings on Mizuho Trust Bank and Mizuho Securities.

TL;DR

Mizuho Bank, Ltd. is the commercial-banking core entity of Mizuho FG (Mizuho FG). On the FSA’s bank license list it is a licensed bank listed as “株式会社みずほ銀行” (city bank), with bank code 0001. It has a bank-license boundary separate from the parent company, the trust bank, the securities company, and the AM company.

2. Operating model

  • The main engine of the Mizuho group for deposits, lending, domestic/foreign exchange, settlement, and corporate finance, carrying the merger lineage of the former Dai-Ichi Kangyo Bank, Fuji Bank, and Industrial Bank of Japan.
  • The bank-license layer (this page) handles the branch / overseas network and the deposit-lending / settlement functions, while the Mizuho FG (Mizuho FG) page handles the consolidated / holding-company strategy.
  • Combine with Mizuho Trust Bank / Mizuho Securities / Asset Management One to see the role division across “bank / trust / securities / asset management”.

3. Why a standalone page matters

Mizuho FG‘s listing, G-SIB status, and group strategy are a different unit of analysis from the bank’s standalone business-improvement orders, branch network, and deposit-lending / FX / corporate-settlement functions. Separating the bank operating company makes it possible to directly track the FSA registration list, the license under the Banking Act, settlement-infrastructure connections, and domestic and overseas locations.
