The Tokyo Stock Exchange will require the 1,600 companies listed on its top Prime Market to simultaneously release financial results and other important data in Japanese and English starting in April 2025.

According to the TSE’s Feb. 26 announcement, the dual-language information disclosure will fuel overseas investments in the Japanese companies.

“We will be drawing much more funds from foreign investors,” Hiromi Yamaji, CEO of Japan Exchange Group Inc., the TSE’s parent company, said at a news conference that day.

Although the TSE wants all significant data disclosed in the two languages at the same time, converting only outlines and other portions of information into English will be permitted.

If simultaneous disclosure of other information in both languages could delay the release of the Japanese version, the companies can make such data available in Japanese first, followed by the English version.

According to the TSE, 90 percent of companies on the Prime Market had disclosed their financial results in English as of the end of December 2023.

But half of the companies did not simultaneously release Japanese and English reports.

The TSE has received complaints from non-Japanese investors who said the “time lag between the releases of the Japanese and English reports was a fatal flaw.”
