Validated By: On Date: Oct. 18th 2022

Yasue Okai [Japanese: 岡井ヤスエ] was a Japanese supercentenarian whose age was validated by the Gerontology Research Group (GRG).


Yasue Okai was born on 25 November 1908 in Osaka Prefecture, Japan. After her marriage, she ran a button shop in Higashiosaka together with her husband Heizaburo. She had a bright and sociable personality, and she was active as a PTA officer at her children’s school. She was also the female head of temples and community events.

Okai was a good cook, so when she was at home, it was her pleasure to serve homemade sushi rolls and oden to her family and neighbors. Until the age of 105, she was well enough to walk around the neighborhood using a walker.

There has been a history of longevity in Okai’s family. Two or three of her sisters lived well into their 90s and 100s.

In November 2018, Okai celebrated her 110th birthday and became a supercentenarian.

Yasue Okai currently lives at a nursing home in Higashiosaka City, Osaka Prefecture, Japan, at the age of 114 years, 27 days, where she has lived since she was around 108.
