Partnership supports the integration of machine-readable climate disclosures from over 800 Japanese companies into the Climate Data Utility, expanding access to nationally-reported Japanese corporate climate data across global markets.

TOKYO, October 30, 2026 – Toshiyuki Miyoshi, Vice Minister for International Affairs at the Financial Services Agency (FSA), and Mary L. Schapiro, Chair of the Climate Data Steering Committee (CDSC), today announced a partnership supporting the integration of Japanese corporate climate data into the Climate Data Utility (the Utility), expanding global access to core climate disclosures made by Japanese companies.

Through the partnership, the Utility integrates greenhouse gas emissions and climate-target information disclosed by more than 800 Japanese companies filed through Japan’s Electronic Disclosure for Investors’ NETwork (EDINET), expanding the Utility’s global coverage to nearly 22,000 companies. The FSA and CDSC will continue to work together to support the future incorporation of sustainability-related information reported under the Sustainability Standards Board of Japan (SSBJ) standards, ahead of the phased introduction of mandatory SSBJ-based disclosures for certain Prime Market-listed companies from the fiscal year ending March 2027.

Japan joins France, whose authorities are members of the CDSC, in contributing nationally-reported corporate climate data to the Utility, demonstrating their leadership on the CDSC’s mission to advance access to high quality comparable climate data, and providing a model for how such partnerships can expand data access across global markets as more jurisdictions adopt structured corporate sustainability reporting.

This partnership builds on the continued leadership of Japanese policymakers and companies on climate-related disclosures, and is made possible by Japan’s world-leading disclosures reporting system which supports structured, digitally-tagged climate data, located in a central open-access repository through the EDINET platform.

“Japan has consistently been at the forefront of global efforts to improve the quality and usability of climate-related financial disclosure, and this partnership reflects that continued leadership,” said Mary L. Schapiro, Chair of the Climate Data Steering Committee. “High-quality, accessible disclosure is foundational to informed investment decisions — giving markets greater confidence to assess risk and allocate capital toward opportunities in new industries, technologies and credible transition strategies. By taking the lead in driving machine-readable, digitally-tagged climate data and partnering with the Climate Data Utility, Japan is helping make that information more accessible, comparable, and usable for decision-makers around the world.” 

“The integration of sustainability-related information disclosed through EDINET into the Climate Data Utility marks an important milestone in building a truly global and interoperable sustainability data infrastructure,” said Toshiyuki Miyoshi, Vice Minister for International Affairs, FSA. “Japan has long promoted both high-quality corporate disclosures and the digital infrastructure needed to make such information accessible and usable. By connecting EDINET with the Climate Data Utility, we are not only expanding global access to sustainability-related information, but also contributing to a more transparent, comparable, and decision-useful data ecosystem.”

Japan has been one of the leading markets for the implementation of the Task Force on Climate-related Financial Disclosures (TCFD) recommendations. Japan has also established the SSBJ standards, which are functionally aligned with the global baseline set by the International Sustainability Standards Board (ISSB). Following recent legislative amendments, certain larger Prime Market-listed companies will be required to provide sustainability disclosures based on the SSBJ standards on a phased basis starting with reporting periods ending in March 2027.

Japan’s contribution to the Climate Data Utility is enabled by its long-established electronic disclosure system, EDINET. Through structured and machine-readable reporting formats, including eXtensible Business Reporting Language (XBRL) tagging for climate data, disclosed information from Japanese companies can be efficiently processed, compared and utilized at scale.

This new partnership will not create any new reporting requirements for Japanese companies. Instead, it demonstrates how sustainability-related information already disclosed through national systems can be made more accessible and useful through global public data infrastructure.
