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 was born on July 25, 1905, just months before Albert Einstein published his special theory of relativity. The first radio broadcast happened in 1906.
His granddaughter Yuko Nonaka said: "He needs a wheelchair to move but he is in good condition".
Nonaka enjoys dipping in a spa and is fond of candies, especially a strawberry sponge cake. Nonaka now enjoys spending time with his family, watching TV-especially sumo wrestling-or reading newspapers.
That sounds like a pretty awesome way to live out your centennial teens, and that gummy smile pulls at our heart strings. Nonaka is now 112 years and 4 months old. His family ran a hot spring which he took over after his parents died.
Mr Nonaka has seven brothers and one sister who live nearby in the town of Ashoro on Hokkaido.
Guinness said Mr Nonaka replaced Francisco Olivera of Spain, who died earlier this year aged 113, as the world's oldest man.
"We are very pleased to announce that we have a new record holder for the oldest living man. Mr. Nonaka's achievement is remarkable-he can teach us all an important lesson about the value of life and how to stretch the limits of human longevity", Craig Glenday, Guinness World Records' editor in chief, said in a statement. Her grandfather loves cake in particular. In 1931, the year he married and became the father of five children. 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. Japan has around 68,000 people aged 100 or older in the country, the government said previous year.
Jiroemon Kimura, a Japanese who died in 2013 at 116, was recognized by Guinness as the longest-lived man in history.
