Born on March 5, 1907 in Niigata, Chitetsu Watanabe previously received his certificate from Guinness World Records as the world’s oldest man.
A couple of days before his death, he had not been able to eat and developed a fever and difficulty breathing.
Watanabe worked in Taiwan for 18 years and after returning to Niigata, he worked for the prefectural government until retirement.
Watanabe said the secret to longevity was to “not get angry and keep a smile on your face”.
Japan has been home to several people recognized as among the oldest humans to have ever lived.
