What is the official name of Japan's central bank?

The official name of Japan's central bank is the Bank of Japan.

The National Bank Act of 1882 established the institution, and the Bank of Japan began operations in 1882. It is headquartered in Nihonbashi, Tokyo, and is commonly abbreviated as BOJ.

The bank issues Japan's currency, the yen, and implements monetary policy. Its policy board makes decisions about interest rates and other measures intended to influence prices, economic activity, and financial conditions. It also acts as the government's bank and provides settlement services for financial institutions.

A frequent mix-up is the distinction between the Bank of Japan and commercial banks such as Mitsubishi UFJ Bank. The Bank of Japan is a central bank: it does not serve ordinary customers in the same way as a retail bank and has a national monetary role.
