The Bank of Japan (BOJ) is the central bank of Japan, responsible for managing the country's monetary policy. Established in 1882, its main goals are to ensure price stability and support economic growth. The BOJ controls the money supply and interest rates, influencing how much money is available for businesses and consumers. One of the BOJ's key tools is quantitative easing, which involves purchasing government bonds to inject money into the economy. This helps lower interest rates and encourages spending and investment. The BOJ also monitors inflation and works to maintain a stable financial system, playing a crucial role in Japan's economy.
