1 account at other banks, in 1 currency, for inward foreign-currency remittances, as the bank publishes them: netbk.co.jp ↗

The source is the bank's inward foreign-currency remittance guide, which gives payment instructions for senders. The page was read only through search-result excerpts, not fetched in full, so the list may be incomplete. The USD row shows the bank's own account at DBTCA, ABA 021001033, with NTSSJPJT required in field 57A of the MT103. A USD alternative follows 'OR' but was cut off in the excerpt. For other currencies the page appears to route through UBS Switzerland AG, but no BIC or account for it was seen. The AUD, CAD, GBP, HKD, NZD and ZAR banks listed (ANZ Melbourne ANZBAU3MXXX, CIBC Toronto CIBCCATTXXX, UBS AG London UBSWGB55XXX, UBS AG Hong Kong UBSWHKHHXXX, ANZ Wellington ANZBNZ22058) are labelled as UBS Switzerland AG's correspondents. They were not extracted as this bank's accounts. The page is undated. Each correspondent BIC is checked against the Swift directory: a BIC missing from it, or registered to a differently named bank, may be a typo or out of date. Confirm settlement instructions with the bank before relying on them.

Sources & method
Every value comes from a public source, such as Swift’s ISO 9362 BIC directory, GLEIF or the OFAC and EU sanctions lists. Most sources are matched on a BIC or an LEI, not on a name.
Swift GPI membership is matched on names and is indicative. A missing sanctions match does not mean that no listing applies. Always screen against the official lists.
The sanctions facts on this page cover the BIC and its LEI only.
An institution is one entry in the directory: a BIC8 in Swift’s directory, or a firm on a tracked register that holds no BIC. Licences held by an institution with a BIC are shown on its page.

- Overview, leadership, regulators and events—researched per institution by an AI model with web search, from the institution's own website and reports, regulators, company registers and news. Figures, people and events link to their source, and each card shows the research date. AI research can be wrong or out of date, so check key facts at the source.
Assess the financial crime risk behind a BIC
A BIC identifies an institution; it does not assess it. The Elucidate FinCrime Index (EFI) is an independent score of the financial crime risk of banks, built for correspondent banking and counterparty due diligence.
