A Japanese man who received his certificate as the world’s oldest man with a raised fist and big smiles earlier this month has died at 112.

Guinness World Records had given the certificate to Chitetsu Watanabe on February 12.

The organisation and the funeral home handling his services confirmed on Tuesday that he died on Sunday.

He had not been able to eat recently and developed a fever and difficulty breathing a couple of days before his death, Japan’s nationally circulated newspaper Mainichi reported, citing family sources.

Mr Watanabe is survived by his five children, 12 grandchildren, 16 great-grandchildren and one great-great-grandchild, Mainichi said.

He was born in 1907 and worked in Taiwan for 18 years. After returning to Niigata, northern Japan, he worked for the prefectural government until retirement.

He grew fruit and vegetables on the family farm and loved cream puffs and bonsai, the Japanese traditional art of raising small sculpted trees.

He used to say the secret to longevity was to keep smiling.

Guinness in Japan offered its condolences to his family.

The oldest living person is also Japanese, Kane Tanaka, a 117-year-old woman.
