Jan. 26, 2026 TSE Summary Report of the English Disclosure Implementation Status Survey as of the End of December 2025

Tokyo Stock Exchange, Inc. (TSE) has promoted English disclosure by listed companies in order to enhance convenience for overseas investors and enable them to make appropriate investment decisions based on the disclosed information. As part of this effort, TSE has been conducting surveys on the English disclosure implementation status of listed companies and providing a list of the results on its website to a wide range of people including overseas investors.
The survey data is aggregated once per year and published as a report. TSE has now finalized the summary report as of the end of December 2025.

As English disclosure became mandatory for companies listed on the Prime Market in April 2025, earnings reports and timely disclosure documents have been, in principle, disclosed simultaneously in Japanese and English. For other types of documents, the English disclosure rates of Prime-listed companies rose to 87.1% (up 4.2% year on year) for IR presentations and 94.9% (up 2.5% year on year) for notices of general shareholders meetings (notices and reference documents), showing that progress has been made in efforts that extend beyond simply meeting mandatory obligations.
