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. Yasuo Fukuda, who served under Yoshiro Mori and Junichiro Koizumi, is the longest-serving Chief Cabinet Secretary in history, having spent over 1,289 days in office.
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 Ichiro Hatoyama, formerly Chief Cabinet Secretary to Gichi Tanaka. Since then, eight other Chief Cabinet Secretaries have become prime ministers, most recently Keizo Obuchi and Shinzo Abe.
