The Financial Instruments and Exchange Act (金融商品取引法 Kin'yū shōhin torihiki-hō?), promulgated on June 14, 2006, is the main statute codifying securities law and regulating securities companies in Japan.
The law provides for:
Registration and regulation of broker dealers and their registered representatives
Disclosure obligations applicable to public companies, investment trusts and similar entities
Tender offer rules
Disclosure obligations applicable to large shareholders in public companies
Internal controls in public companies; in this role the law is often referred to as J-SOX, a reference to the American Sarbanes-Oxley Act (SOX).
