Japanese financial institutions play a crucial role in the country's economy, providing services such as banking, insurance, and investment. Major types include commercial banks, trust banks, and insurance companies, which cater to both individual and corporate clients. These institutions are regulated by the Financial Services Agency to ensure stability and consumer protection. In addition to traditional banks, Japan has a unique system of shinkin banks and credit unions that serve local communities. The Tokyo Stock Exchange is a key platform for trading securities, while Japan Post Bank offers postal savings services, making financial access more widespread across the nation.
