Oldest living Prime Ministers of Japan
Not all prime ministers live to become the oldest of their time. Of the 54 deceased prime ministers, 18 eventually became the oldest of their time, while 36 did not (including all 5 prime ministers who died in office and 31 others). Matsukata Masayoshi became the oldest living prime minister when he was appointed in 1891 and remained so until his death in 1924, for a record 33 years and 55 days. Keisuke Okada became the oldest living prime minister after the death of Hiranuma Kiichirō, but he survived Kiichirō by only 46 days.
On three occasions the oldest living prime minister lost this distinction not by his death, but due to the appointment of a prime minister who was older. Itō Hirobumi lost this distinction when Kuroda Kiyotaka was appointed. Kuroda Kiyotaka lost this distinction when Sanjō Sanetomi was appointed. Yamagata Aritomo lost this distinction when Matsukata Masayoshi was appointed.
Tomiichi Murayama was the oldest to acquire this distinction at the age of 95 years, and 217 days. Nobusuke Kishi, who was 90 years, and 297 days old when he died on 7 August 1987 is the oldest prime minister to die without ever acquiring this distinction. Tsutomu Hata, who was 82 years, and 4 days old when he died on 28 August 2017 is the most recent prime minister to die without ever acquiring this distinction.
