Handling of the trust-bank route

BNY’s official Japan page explains that it acquired a Japanese trust-bank business in 2009 年, leading to the present Bank of New York Mellon Trust Bank, Ltd. Another official disclosure page also describes Bank of New York Mellon Trust Bank as a trust bank established in Japan, a registered financial institution whose main business is custodial services for corporate clients.

For this reason, FinWiki does not mass-produce bny-mellon-trust-bank as a standalone page, but treats this page as the umbrella route for foreign-bank branch registry and trust-company registry. Only when necessary does it proceed from this section to a custody / trust-bank comparison with Master Trust Bank or Custody Bank of Japan (CBJ).

2. History (timeline excerpts)

Year	Event
1968	The Bank of New York begins its Japan business (start of banking operations in Tokyo)
1970s〜80s	Expanded custody / transaction-banking business during the era of Japanese banks’ global expansion
1989	Supported the overseas securities issuance of many Japanese companies through the stock-investment-agent business (ADR agent) (established its position as an ADR depositary for US-listed Japanese companies)
1990s〜2000s	Fully developed the custody business as Japanese banks’ and pension funds’ overseas asset management expanded
2007-07-01	The Bank of New York + Mellon Financial merge → BNY Mellon launched (the birth of a global bank specialized in custody / asset management)
2010s	Expanded global-custody mandates from Japanese banks and pension funds (GPIF, etc.) (tailwind from yen depreciation / a shift to overseas investment)

3. Business-segment map

5. Supervision & regulation

Supervisor: the FSA — as a trust bank / in-Japan branch
US-side supervision: the FRB (Board of Governors of the Federal Reserve System) / OCC (Office of the Comptroller of the Currency) / FDIC, subject to the global stress test DFAST
Recent issues:
- Rising overseas-asset-management ratio of GPIF and public pensions → structural expansion of custody demand
- Yen depreciation / shift to overseas investment → growth in mandated assets as Japanese banks and asset managers build up overseas assets
- Foreign Exchange Act / inward-direct-investment screening → regulatory response in the overseas-asset-custody business

[!info] Verification status confidence: likely. A summary based solely on public information (Wikipedia + BNY Mellon group official IR + FSB publications). Because the latest financials specific to the Japan bases (in-Japan branch assets, headcount scale, mandated assets) are undisclosed or consolidated into the parent, this article refrains from numerical detail and concentrates on an overview of structure, history, and strategy.
