Japan Exchange Group (JPX), formed in 2013 through the merger of the Tokyo Stock Exchange and the Osaka Securities Exchange, is a central player in the East Asian capital market ecosystem. JPX oversees both securities and derivatives markets, offering a wide range of trading services across equities, bonds, ETFs, and commodity futures, while also providing clearing, settlement, and market data services. The Nikkei 225 and TOPIX indices are widely used in product development and as key benchmarks for market performance assessment.

On January 25, 2021, Shenzhen Stock Exchange and JPX signed a memorandum of understanding to deepen cooperation, focusing on cross-border index collaboration and ETF connectivity. In April of the same year, the two exchanges launched a landmark ETF connectivity project, with products listed simultaneously in both markets tracking the Nikkei 225 Index and the Guangdong-Hong Kong-Macao Greater Bay Area Innovation 100 Index, enabling cross-market index investment linkage. Building on this foundation, the two sides continue to advance joint development and promotion of index products, broaden connectivity between the Chinese and Japanese capital markets, and provide investors with diversified cross-border index allocation tools, supporting the collaborative growth of the two countries’ innovation-driven economies.
