TOKYO - Japan's Prime Minister Fumio Kishida is set to replace his foreign and defense ministers, broadcaster NHK reported on the eve of an expected cabinet reshuffle as the beleaguered premier looks to boost his sagging popularity.

NHK reported on Tuesday that the current foreign minister Yoshimasa Hayashi will be succeeded by Yoko Kamikawa, a former justice minister who oversaw the execution of the leader of the Aum Shinrikyo doomsday cult that carried out a deadly sarin gas attack on the Tokyo subway in 1995.

Recent opinion polls show Kishida, who became prime minister less than two years ago, scoring lower approval than disapproval ratings, and he has said he plans to reshuffle his cabinet

According to NHK, Minoru Kihara will replace Yasukazu Hamada as defense minister.

Kishida is otherwise considering retaining Finance Minister Shunichi Suzuki and Industry Minister Yasutoshi Nishimura, Kyodo news agency reported.

Recent opinion polls show Kishida, who became prime minister less than two years ago, scoring lower approval than disapproval ratings, and he has said he plans to reshuffle his cabinet and make changes in the leadership of the ruling Liberal Democratic Party (LDP) as early as Wednesday.

The Yomiuri Shimbun newspaper reported Kishida has also decided to keep Hirokazu Matsuno in his current post as chief cabinet secretary, a key position that involves being the main government spokesperson and coordinating policy among ministries.

Shinzo Abe and Yoshihide Suga, two prime ministers before Kishida, both served as chief cabinet secretary before becoming premier.

Kishida appointed Suzuki as finance minister when he formed his first cabinet in October 2021. Continuity at the finance ministry would underscore his administration's focus on keeping sharp yen falls in check, and compiling a fresh package of measures to cushion the blow from rising living costs.
