About the FTSE JPX Blossom Japan Index

The FTSE JPX Blossom Japan Index is developed by FTSE Russell, a global index provider, to measure the performance of companies in Japan that demonstrate specific commitments to environmental, social, and governance (ESG) practices. The index is widely used in the creation and evaluation of sustainable investment funds and other financial products.

FTSE Russell evaluates companies across areas such as corporate governance, health and safety, anti-corruption, and climate change. Companies included in the FTSE JPX Blossom Japan Index meet various ESG-related criteria.
