The Bank of Japan fell further behind its global peers on efforts to promote gender equality as it returned to an all-male lineup of executive directors after reshuffling its senior positions.

Tokiko Shimizu, the central bank’s first and only female director, has been replaced by Kazushige Kamiyama after finishing a four-year term, the BOJ said Monday. All six executive director positions are now filled by men.

As Gov. Kazuo Ueda and his deputies will stay in place at the top of the bank, the personnel moves are unlikely to impact the BOJ’s monetary policy stance.
