JPX Market Innovation & Research and Nikkei will replace 31 constituents in the JPX-Nikkei Index Human Capital 100, effective from the calculation on Aug. 29.

Suzuki Motor (TYO:7269) will be added to the index, while Honda Motor (TYO:7267) is among those removed, according to a statement on Friday.

Launched in July, the move marks the index's first annual review, selecting companies based on human capital scores from ESG Book as of the end of June and factors like salary growth rates.

Firms removed from the broader JPX-Nikkei Index 400 are automatically excluded from the human capital-focused index.
