Kiyotaka Mizuno was born in Iwata, Shizuoka Prefecture, Japan, on 14 March 1914. In his youth, he reportedly served as a guard for the Emperor and served on the continent during World War II, narrowly escaping death before returning to Iwata.
After the war, he worked as a farmer, producing shrimp potatoes and white leeks, until his 80s. At the age of 108, he lived at home with his eldest son and his family, and was able to eat and bathe on his own.
Following the death of Kentaro Muramatsu of Yaizu City on 23 November 2021, Mizuno became the oldest living man in Shizuoka Prefecture.
His age was verified by Japan’s Ministry of Health, Labour, and Welfare (MHLW), as well as Ryohei Asano and Yumi Yamamoto, and validated by LongeviQuest on 11 July 2024.
