Shiro Moriyama (born 6 March 1911) is a Japanese supercentenarian whose age is currently unvalidated by the Gerontology Research Group (GRG). He is the 3rd oldest known living man in Japan, behind Mikizo Ueda and Shigeru Nakamura.


Shiro Moriyama was born in Shizunai, Hokkaido on 6 March 1911. His father, Hirosaku Shiroyama (b. 1866), moved to the Hokkaido region in 1899 to mine for gold. His older brother, Katsu Moriyama (1905-2012/2013), lived to the age of 107, making them among the longest-lived sibling pairs with a combined age of over 217.

At the age of 99, he was sent a congratulatory letter from his city's mayor and a souvenir from Yuki Nakamura, Chairman of the Social Welfare Council, for his contributions in promoting forestation efforts. At this age, he still traveled by himself on the bus, and enjoyed karaoke and going to his prefecture’s many famous hot springs, such as the Shizunai Onsen. He has lived in a care home for the elderly since 2014. He became the oldest living man in the Hokkaido region following the death of Kinsaku Hayashinaka in November 2020. He celebrated his 110th birthday in 2021, becoming the 8th man from his prefecture to achieve this milestone.

Shiro Moriyama currently lives in Shinhidaka, Hokkaido at the age of 110 years, 323 days.
