Koto Okubo (大久保 琴 Ōkubo Koto?, 24 December 1897 – 12 January 2013) was a Japanese supercentenarian who, at the time of her death aged 115 years and 19 days, was recognized as the oldest woman in the world and the second oldest living person behind Jiroemon Kimura. At the time of her death, Okubo was one of only 29 people verified to have surpassed a 115th birthday.
Koto Okubo became the oldest woman from Japan and Asia after the death of Chiyono Hasegawa on 2 December 2011. The Ministry of Health, Labour and Welfare did not announce her name officially (only her residence and age were released). Furthermore, at that time, her record was not identified and recognized by the Gerontology Research Group.
