# オーストラリア・コモンウェルス銀行日本 (Commonwealth Bank Japan)

## Wiki route

Commonwealth Bank Japan sits under [[foreign-financial-institutions/INDEX|foreign-financial-institutions INDEX]] and is a foreign-bank branch route inside [[foreign-financial-institutions/foreign-bank-branches-japan-index|the Japan foreign-bank branch registry]]. Read it with [[securities-firms/anz-bank-japan|ANZ Bank Japan]], [[foreign-financial-institutions/national-australia-bank-japan|National Australia Bank Japan]], [[financial-licenses/foreign-bank-branch-license-route|foreign-bank branch licensing]], and [[finance/cross-border-m-a-japan|cross-border finance]].

Use this page for Australia-Japan wholesale banking, structured asset finance, markets, and foreign-bank agency questions. It is not a Japan retail bank page.

## Overview

Commonwealth Bank of Australia's Tokyo branch is a wholesale foreign-bank branch. CBA's public Asia page states that the Tokyo branch was established in 1986 and does not offer retail banking services to individual customers.

The branch is worth promoting from registry-only because the public disclosure identifies activities including funding / investment, FX, interest-rate swaps and futures, structured asset finance, commodity-related intermediary activity, and deposit business. That makes it a peer to [[securities-firms/anz-bank-japan|ANZ]] and [[foreign-financial-institutions/national-australia-bank-japan|NAB]] in the Australia-Japan corridor.

## Research Checklist

1. Confirm the legal entity: Tokyo branch versus CBA Australia retail bank.
2. Check FSA foreign-bank branch and agency lists for current licensing.
3. For deal analysis, separate structured asset finance, portfolio / funding activity, commodity-related agency, and derivatives.
4. Do not route individual Australian retail-account issues to the Japan branch.
5. Compare Australia-Japan corridor questions with [[securities-firms/anz-bank-japan|ANZ]] and [[foreign-financial-institutions/national-australia-bank-japan|NAB]].
