Japan's Climate Disclosure Rules: What You Need to Know

Summary Japan’s financial regulator requires the largest Tokyo Stock Exchange companies to report climate information under Sustainability Standards Board of Japan (SSBJ) standards, which match the global standards IFRS S1 and IFRS S2. Reporting starts with fiscal years ending March 2027 for companies worth ¥3 trillion or more; supply-chain (Scope 3) emissions and an independent check of the figures follow in year two. Coverage widens to ¥1 trillion in 2028 and ¥500 billion in 2029, reaching 284 companies and 80.8% of the value of the exchange’s top segment, the Prime Market.
