May 20, 2025 JPXJPXI Japan Exchange Group and FTSE Russell announce collaboration to align FTSE Blossom Japan Index Series with TOPIX

JPX Market Innovation & Research Inc. (“JPXI”), a subsidiary of Japan Exchange Group (JPX) and FTSE Russell, the global index provider, today announce an agreement to align the FTSE Blossom Japan Index and the FTSE Blossom Japan Sector Relative Index with the Tokyo Stock Price Index (TOPIX).
In response to customer feedback, the longstanding FTSE Blossom universe will be aligned with TOPIX constituent information, which is established in Japan and overseas as a broad benchmark for Japanese stock prices. The collaboration will ensure the indices continue to facilitate ESG integration into the Japanese market.
As a result of the agreement, the name of the FTSE Blossom Japan Index and FTSE Blossom Japan Sector Relative Index will be changed to the FTSE JPX Blossom Japan Index and FTSE JPX Blossom Japan Sector Relative Index. All non-TOPIX constituents will become ineligible for FTSE JPX Blossom Japan Index Series.
To enable a smooth transition, the use of TOPIX constituent information will be applied from the December 2025 index rebalance.

Satoshi Futagi, President and CEO of JPX Market Innovation & Research, comments:
“We are pleased to be involved in enhancing the FTSE Blossom Japan Index series, a widely accepted sustainable index, by utilizing information from TOPIX, our flagship index representing Japanese stocks. TOPIX is an index with high functionality as a market benchmark for Japanese stocks, characterized by market representativeness and investability, with active trading of derivatives such as futures at the Osaka Exchange. Through this initiative, we expect that index investing based on indices focusing on corporate sustainability will become more widespread for Japanese stocks, leading to further development of the Japanese stock market through the strengthening of corporate sustainability initiatives.”

Fiona Bassett, CEO of FTSE Russell, comments:
“We’re delighted to build on our collaboration with JPX to enhance the FTSE Blossom Japan indices. Since launch, the indices have been widely used by customers looking to integrate ESG risks and performance into their equity strategies. In response to customer feedback, this is an important product enhancement and the introduction of constituent information from TOPIX will ensure the indices continue to facilitate ESG integration into the Japanese market.”

The FTSE Blossom Japan Index Series has been adopted by the Government Pension Investment Fund (GPIF) in Japan since 2017 and has been the top performer among all Sustainable Indices mandated by the GPIF according to their latest ESG Report *.
