The proportion of female executives at companies listed on the Tokyo Stock Exchange's Prime top-tier section stood at 18.4% as of July, up 2.3 percentage points from the previous year, a survey by the Japan Business Federation, or Keidanren, showed Thursday.

Still, the figure remained below the government's target of increasing the share of female executives at companies on the Prime section to at least 19% by 2025. The target for 2030 is at least 30%.

Among Keidanren member firms traded on the top-tier section, the proportion of female executives rose by 2.2 points to 19.0%, reaching the government's interim target.
