Tokyo: Chitetsu Watanabe, a 112-year-old man from Japan, has been crowned the world’s oldest male, and was officially given the title at a nursing home in Niigata where he currently resides.

Born on on March 5, 1907 in Niigata, north of Tokyo, Watanabe said that the secret to his long life is to “not get angry and keep a smile on your face”.

Watanabe, is married with five children, says that he has a penchant for sweets such as custard pudding, but it appears to have done him no harm. He keeps himself busy by exercising, making origami, and doing calligraphy and math exercises.

The previous record holder, Masazo Nonaka, who was also from Japan, died last month at 112 years and 266 days.

Meanwhile, the oldest living person is also Japanese, Kane Tanaka, a 117-year-old woman. On January 2 this year, she extended her own record after she celebrated her 117th birthday.

Tanaka says her secret to longevity is family, sleep and hope and that she would like to live until at least 120 years old.

Japan has one of the world’s highest life expectancies and has been home to several people recognised as among the oldest humans to have ever lived, as per an AFP report.
