The chief cabinet secretary of Japan (内閣官房長官, Naikaku-kanbō-chōkan) is a member of the cabinet and is the leader and chief executive of the Cabinet Secretariat of Japan. The chief cabinet secretary coordinates the policies of ministries and agencies in the executive branch, and also serves as the government's press secretary. The secretary is a statutory member of the National Security Council, and is appointed by the emperor upon the nomination by the prime minister. The chief cabinet secretary is the second in line of succession to the prime minister, and 1st if the office of the deputy prime minister is unoccupied.

History

In March 1879, the precursor of the position, the Secretary-General of the Cabinet, was created. From 1885, it was included as part of the cabinet system, and the position was known in Japanese as 内閣書記官長 (naikaku-shokikan-chō). The modern position was created on May 3, 1947, shortly after the passage of the Constitution of Japan, and elevated to ministerial status in 1966.

Since 1947, the office of Chief Cabinet Secretary has been regarded as a stepping stone to the post of Prime Minister. The first chief cabinet secretary to become Prime Minister was Ichirō Hatoyama, who served in the position under Tanaka Giichi. Since then, eight other former chief cabinet secretaries have become prime ministers, most recently Shinzō Abe, Yasuo Fukuda, and Yoshihide Suga.

Yoshihide Suga, who later became Prime Minister of Japan, served as Chief Cabinet Secretary under Shinzo Abe for nearly eight years, making him the longest-serving chief cabinet secretary in history, having overtaken the previous record of 1,289 days in office set by Fukuda on July 7, 2016.

The current chief cabinet secretary is Yoshimasa Hayashi, who took office on December 14, 2023.
