Koto Okubo

Koto Okubo [Japanese: 大久保 琴] was a Japanese supercentenarian who, at the time of her death, was the oldest validated woman in the world and the second-oldest person in the world, behind Japanese man Jiroemon Kimura.


Koto Okubo was born in Japan on 24 December 1897 in Tokyo. She spent her last days in her nursing home in Kawasaki with the company of her son. She was the last surviving woman in the world born in 1897.

She was the oldest living woman in Japan since Chiyono Hasegawa’s death on 2 December 2011, and the oldest living woman in the world since Dina Manfredini’s death on 17 December 2012, just a week before her 115th birthday.

Okubo died in Kawasaki, Kanagawa, Japan on 12 January 2013, at the age of 115 years, 19 days. She was survived by her son. She was succeeded as the world’s oldest living woman by Misao Okawa.
