Liberal Democratic Party lawmaker Yosuke Tsuruho plans to resign as chairman of a parliamentary committee to take responsibility for a gaffe about a powerful earthquake that struck the Noto Peninsula in central Japan last year, sources said Saturday.

According to a senior official of the ruling LDP, Tsuruho is poised to step down from the post of chairman of the Budget Committee in the House of Councillors, the upper chamber of parliament, following criticisms of the verbal blunder from both the ruling and opposition sides as well as by people affected by the Jan. 1, 2024, temblor.

Tsuruho has already submitted a letter of resignation as Budget Committee chairman to Upper House President Masakazu Sekiguchi, the senior party official said.
