What It Is
J-SOX, or Japan's Financial Instruments and Exchange Act (FIEA) internal control provisions, is a regulatory framework mandating internal controls over financial reporting (ICFR) for listed companies.

- Mandatory for ~3,800 listed firms and subsidiaries to ensure financial transparency, investor trust.
- Mitigates misstatement risks, reduces audit costs via efficiency; builds governance resilience.
- Enhances reputation, lowers capital costs amid auditor shortages.
Implementation Overview
- Phased: governance, scoping, design, testing, reporting, monitoring.
