The Financial Services Agency (金融庁, Kin'yū-chō, FSA) is a Japanese government agency and an integrated financial regulator responsible for overseeing banking, securities and exchange, and insurance sectors in order to ensure the stability of the financial system of Japan.

The agency operates with a Commissioner and reports to the Minister of State for Financial Services.

It oversees the Securities and Exchange Surveillance Commission and the Certified Public Accountants and Auditing Oversight Board.

[2] The FSA was under the supervision of the Financial Reconstruction Commission (FRC) until January 2001, when the FRC was abolished and the FSA became directly subordinate to the Cabinet Office through a State Minister.

These are organs of the Ministry of Finance but are directed and supervised by the FSA Commissioner in this capacity.
