Prime Minister Fumio Kishida appointed his eldest son as executive secretary in charge of political affairs on Oct. 4.

Shotaro Kishida, 31, worked previously as a government-paid secretary at his father’s office.

He will replace Takayoshi Yamamoto, who served in the position since the Kishida administration began last year. Yamamoto will resign and work at the elder Kishida’s office.

Chief Cabinet Secretary Hirokazu Matsuno declined to comment on the appointment at a news conference on the morning of Oct. 4.

However, he said that, generally speaking, “appointments are appropriately made based on appointees’ personalities and perceptions.”
