SSBJ · ISSB · Japan Sustainability Disclosure
Japan's Sustainability Standards Board (SSBJ) is introducing mandatory sustainability disclosures aligned with ISSB standards. Our Tokyo-based team and AI platform help you meet these requirements efficiently.
We're working with a select number of Prime Market companies preparing for SSBJ compliance.
What is the SSBJ?
The Sustainability Standards Board of Japan (SSBJ) has developed disclosure standards aligned with the ISSB's IFRS S1 and S2. These standards will become mandatory for companies listed on the Tokyo Stock Exchange Prime Market.
SSBJ standards require disclosure on governance, strategy, risk management, and metrics & targets — with Japan-specific considerations for climate transition plans and value chain emissions.
March 2025
Final SSBJ standards published (SSBJ-1, SSBJ-2, SSBJ-3).
FY 2027 (April 2027)
Mandatory for Prime Market companies with market cap ≥ ¥3 trillion. Reports due in 2028.

Phased expansion to additional Prime Market and Standard Market companies.
