Masutaro Sato

Masutaro Sato (16 January 1870 - 6 October 1978) was a Japanese centenarian and at the time of his death the world's second-oldest man, behind Charlie Phillips (while Phillips is validated as born in 1870, research suggests he was a year older), aged 108 years, 263 days. He was also the oldest living man in Japan as well as the oldest living person in Japan. His predecessor as Japan's Oldest Man is unknown due to Shigechiyo Izumi being still alive and thought to be older, but his predecessor as Japan's Oldest Person was Koume Hirakawa. He was succeeded as Japan's Oldest Man by Tanaka Kushida and as Japan's Oldest Person by Matsu Yoshikuni.
