Eiju Tsuru

Eiju Tsuru (4 February 1879 - 11 January 1990) was a Japanese supercentenarian and at the time of his death Japan's oldest man, a title he held from Shigechiyo Izumi's death on 21 February 1986 to his own death on 11 January 1990 aged 110 years, 341 days.

Tsuru was the last Russo-Japanese War veteran living in Japan at the time of his death. Only one veteran, Mamoru Eto (1883-1992), who died in the United States, died after him. At the time of Tsuru's death, he was the oldest Japanese man ever, a title he retained until Gengan Tonaki surpassed him in age. He was also the first Japanese man to reach the age of 110.

Upon Tsuru's death, 109-year-old Kiichi Fujiwara became Japan's oldest man.
