야마가타 아리토모
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 (b. 1841) lost this distinction when Kuroda Kiyotaka (b. 1840) was appointed. Kuroda Kiyotaka lost this distinction when Sanjō Sanetomi (b. 1837) was appointed. Yamagata Aritomo (b. 1838) lost this distinction when Matsukata Masayoshi (b. 1835) was appointed.
