A supercentenarian whose family has run a hot springs inn in northern Japan for four generations has been certified as the world's oldest living man.
Nonaka, who lives in a family-run hot spring inn on the northern island of Hokkaido, was presented with the certificate on Tuesday by the Guinness World Records.
According to his granddaughter Yuko, Nonaka enjoys soaking in a hot spring once a week and indulges in candies, especially cakes. That honor goes to Jiroemon Kimura, also from Japan, who was born on April 19, 1897, and died on June 12, 2013, at the age of 116 years and 54 days.
Although Nonaka is the oldest living male, Guinness World Records said it now has no female equivalent for the title since Violet Brown of Jamaica died last September at age 117. He married Hatsuno in 1931 and have five children with her. Honaka has outlived his siblings and wife.
Mr Nonaka manoeuvres himself in his wheelchair, reads a newspaper after breakfast every morning, and loves to watch sumo wrestling and samurai dramas on TV.
The world's oldest living man also likes to spend time with his family, and their two pet cats called Kuro and Haru.
Mr Nonaka assumes the title after Spain's Francisco Nunez Olivera died in February aged 113, Guinness World Records said.
Nonaka is said to be extremely fond of his pets and added if he does not like his dinner he would often give it to his pets, but tries to hide it from his family. While Nonaka believes his longevity is due to his likings to candies and the springs, his daughter thinks it is because he lives life stressless way. She claimed it was because he lives his life in a way that does not bring him stress.
The world's oldest living person is Nabi Tajima, a 117-year-old resident of the southern Japanese prefecture of Kagoshima, according to the US -based Gerontology Research Group.
