Japan’s latest ISSB-related output is a meeting-report publication rather than a new Japanese disclosure rule text. On May 27, the Financial Services Agency published fiscal 2025 deliverables for its outreach on discussions related to the International Sustainability Standards Board, and the release links to a September 2025 Sustainability Standards Advisory Forum, or SSAF, meeting report. For business readers, the value is that it shows where Japan is doing some of the technical work around global sustainability disclosure.
Who is in the room
The member list reproduced on the FSA page shows Japan engaging through a fairly broad international forum. It includes the Sustainability Standards Board of Japan alongside bodies such as Canada’s CSSB, India’s ICAI, the Korea Accounting Institute and Financial Services Commission, Saudi Arabia’s SOCPA, EFRAG, Switzerland’s SIF and the UK’s FRC. The same snippet also lists ISSB participants, including vice chair Sue Lloyd, plus observers such as the European Commission, IOSCO and GRI.
That mix matters because it shows Japan’s ISSB outreach running through a structured discussion channel with peer standard setters, regulators and reporting bodies, not as a one-off bilateral conversation.
What the report adds
The agenda text carried on the page reads like an implementation worklist. It refers to support for adopting IFRS S1 and IFRS S2, educational materials, SASB standards work, climate-related transition-plan disclosure and links to the GHG Protocol. It also mentions an agenda paper and future scheduling, pointing to a working session on how the standards land in practice.
For finance and reporting teams, that is the useful read-through. The FSA publication does not clearly present final conclusions from each topic, but it does show which technical questions Japan is helping to discuss internationally as the sustainability rulebook gets translated into reporting process and disclosure language.
One caveat deserves to sit in plain view. The FSA page says its translated pages may not be correct, and the material available there does not provide a clean, item-by-item record of decisions. So the safe takeaway is narrow but still useful: the publication maps participants and topic areas, not final rulings or a new domestic policy step.
