Japan Exchange Group, Inc. (株式会社日本取引所グループ, Kabushiki-gaisha Nippon Torihikijo Gurūpu, Corporate Number: 9120001098575), abbreviated as JPX or Nippon Torihikijo, is a Japanese financial services company headquartered in Tokyo and Osaka.

The exchange group was formed by the merger of Tokyo Stock Exchange Group, Inc. [ja] and Osaka Securities Exchange Co., Ltd. on January 1, 2013. As a result of this merger and market reorganization, the Tokyo Stock Exchange (TSE) became the sole securities exchange of JPX and the Osaka Exchange (OSE) became the largest derivatives exchange of JPX.
JPX owns three licensed "financial instruments exchange" corporations: Tokyo Stock Exchange, Inc., Osaka Exchange, Inc., and Tokyo Commodity Exchange, Inc. (TOCOM). It also has an IT services and research arm, JPX Market Innovation & Research, Inc. (JPXI), and a central clearing counterparty, Japan Securities Clearing Corporation (JSSC).
As of July 2024, JPX is the world's fifth-largest stock exchange operator, behind NYSE, NASDAQ, SSE, and Euronext, exceeding $5.8 trillion in July 2024.

## History

The remainder of the merger was realized through a series of changes:
