Masazo Nonaka, from Ashoro, Japan, is officially the oldest man alive. Nonaka was born on July 25, 1905 - 42 days before the Russo-Japanese War ended.
He now lives with his family, who own and manages a 105-year-old hot springs inn. Nonaka also spends his time watching TV - sumo wrestling in particular and reading newspapers.
According to the Guinness World Records, Nonaka now spends his time after retirement watching television, sumo wrestling in particular, reading newspapers and also indulging in candies and cakes.
Yuko Nonaka, his granddaughter, said he put much of his longevity down to a soft spot for Japanese and Western candies. The supercentenarian received the title after Francisco Nunez Olivera of Spain died this year at the age of 113, Guinness World Records said.
According to his granddaughter Yuko, Nonaka enjoys soaking in a hot spring once a week and indulges in candies, especially cakes.
In 1931, he married Hatsuno and went on to have five children with her.
Mr Nonaka, wearing a knit cap and a kimono-style jacket, flashed a smile and posed for a group photo with his family, making a victory sign with his right hand.
He dug into the cake with a spoon after it was cut, and said, "Delicious", according to NHK public television. Japan had another record holder with Jiroemon Kimura who died at 116 in 2013.
A 117-year-old Japanese woman, Nabi Tajima, who is now the oldest living person in Japan, is expected to be certified as the world's new oldest person, replacing Violet Moss-Brown of Jamaica, who died in September at the age of 117.
Japan has around 68,000 people aged 100 or older in the country, the government said previous year.
