Japan's stock market will be closed for 3 days from 21 to 23 September 2026. While cash trading will be suspended, some markets, including Nikkei 225 futures and USD/JPY, will continue trading. The market is scheduled to reopen on Thursday, 24 September, with attention focused on price discovery during the closure and the possibility of a gap at reopening.
Japan's cash equity market will be closed from 21 to 23 September 2026. While regular trading in Tokyo Stock Exchange-listed shares will be suspended, the cash market is expected to reopen on Thursday, 24 September. Overseas and futures markets will continue moving during the closure, limiting the amount of information reflected in cash-market closing prices.
Nikkei 225 futures will continue trading, and USD/JPY could also become active. Derivatives markets, including Nikkei 225 futures traded through Osaka Exchange, are expected to remain open during the market holiday and serve as indicators of market expectations ahead of the cash market's reopening.
Price discovery during the closure could diverge from cash-market valuations, and new information may be reflected all at once when trading resumes. The linkage between the cash and futures markets may temporarily weaken, while the factors behind any gap will depend on new information and changes in valuations.
Once trading resumes, new prices will be established through the opening auction before trading begins, starting the process of incorporating information accumulated during the closure. Investors are advised to assess the situation by considering four indicators together: Nikkei 225 futures, USD/JPY, global markets and company news.
