Japan Exchange Group
The Tokyo-listed holding company formed on 1 Jan 2013 when the Tokyo Stock Exchange merged with the Osaka Securities Exchange. Its derivatives arm, Osaka Exchange (OSE), has held all of Japan's listed securities derivatives since 24 Mar 2014 and its commodity futures since 27 Jul 2020. Osaka claims a lineage back to the Dojima rice market, where trading began around 1697 and which the shogunate formally recognised in 1730. It is often called the first organised futures market (section 24). The modern franchise is the Nikkei 225: futures from 3 Sep 1988, options from Jun 1989, the one-tenth Nikkei 225 mini from 18 Jul 2006, and micro futures and mini options from 29 May 2023 (Wikipedia/JPX history; Mondo Visione). In 2025 JPX's derivatives traded 418.75m contracts, its third-highest year, with 40.2% of them in the night session (JPX, 30 Dec 2025). For a trading book JPX is the North Asian venue that went with the global trend — smaller contracts, longer hours, more expiries — rather than against it like Korea in 2012. It also shows the venue under stress. Barings' Nikkei bets were spread between Osaka and Singapore in 1995. A hardware fault stopped Tokyo's cash market for a full day on 1 Oct 2020. And on 5 Aug 2024, when the Nikkei 225 fell 12.4%, Osaka's futures circuit breaker fired twice (FSA, Jan 2025; Shared facts).
