The Tokyo Stock Exchange is closed today, Monday, July 20, 2026, for Marine Day (Umi no Hi), a national holiday honoring Japan’s maritime economy. Cash equity trading on the TSE, along with the broader JPX group markets, resumes tomorrow, Tuesday, July 21. Derivatives markets are an exception. Osaka Exchange and Tokyo Commodity Exchange continue to offer holiday trading on instruments like Nikkei 225 futures and Platts Dubai crude oil futures, a practice JPX introduced in 2022 to give investors hedging access during national holidays.
