## Overview The Bank of Japan (BoJ), established in 1882, is the nation’s central bank and the sole issuer of the Japanese yen[1][6][7]. Its primary missions are to maintain price stability and ensure the stability of the financial system, roles it fulfills through monetary policy, currency issuance, and oversight of financial institutions[5].

In response, it pioneered unconventional monetary policies, such as the
