Chitetsu Watanabe [Japanese: 渡邉智哲] (born 5 March 1907) is a validated Japanese supercentenarian who is currently the world's oldest validated living man.


Watanabe was born in the Urakawahara suburb of Joetsu, Niigata, Japan on 5 March 1907. He was born as the first of eight children of his father Haruzo and mother Miya. His parents were farmers. After graduating from an agricultural high school, Watanabe became a staff member of Dai-Nippon Meiji Sugar and moved to Taiwan to help conclude sugar cane plantation contracts there. During his 18 years in Taiwan, Watanabe married Mitsue and four out of five of their children were born there. His first child and son is Tetsuo Watanabe. He also served in the military towards the end of the Pacific War in 1944. He returned to Niigata after the Second World War, and worked for a departure agency.

In 1974, he and his son Tetsuo had built a new family home. They also had about a hectare worth of farm next to the new home. He also worked on his bonsai until he was set to live in a nursing home. He also presented his work at local exhibitions until 2007.

After retiring, Watanabe lived with one of his son's family until the age of 108, when he moved to a care facility in Joetsu, Niigata, Japan. As of 2019, he has 12 grandchildren and 16 great-grandchildren. In January 2019, in an interview for a local newspapers, he said that the secret to his longevity is to "not to get angry and keep a smile on your face".

Longevity Records

Watanabe has been the oldest living person in Niigata Prefecture since the death of Tora Kosugi on 11 December 2018. He became the oldest living man in Japan following the death of 113-year-old Masazo Nonaka on 20 January 2019.

Since the death of Masazo Nonaka, Watanabe has been the oldest living man whose age is validated by the Gerontology Research Group. However, at the time there were other claimants to the world's oldest man title, such as Gustav Gerneth and Domingo Villa Avisencio (both of whom are now deceased), whose ages are not validated. On 12 February 2020, Watanabe was officially recognised as the world's oldest man by the Guinness World Records.
