TOKYO — The Tokyo Stock Exchange (TSE) will require all 1600 or so companies listed on the top-tier Prime market to disclose key information in English, starting in March 2025, Nikkei has learned, in its latest move to attract more foreign investors to the country’s top bourse. 

The companies will first be required to simultaneously disclose financial results in Japanese and English. Although as of August 97% of companies listed on the Prime market already publish some documents in English, this information is mostly limited to financial statements, according to the TSE. Only about 40% of companies release their financial results in English and Japanese simultaneously.
