Tomi Ōno (Japanese: 大野とみ) is a Japanese supercentenarian whose age has been validated by LongeviQuest. She is currently the oldest living person in Yamanashi Prefecture.
Tomi Ōno (Japanese: 大野とみ) was born in Tsuru City, Yamanashi Prefecture, on 24 February 1913, as one of eight siblings. She spent many years living in Tokyo, including during her marriage. During World War II, she remained at her home in Shinagawa rather than evacuating. Fortunately, the Nishi-Oi area of Shinagawa Ward where she lived escaped major damage during the Tokyo air raids, allowing her to survive the war. In her 70s, she contributed to society by sharing her wartime experiences as a storyteller.
After her husband passed away, Ōno lived alone in Tokyo until the age of 87. Following a decline in her health, she returned to her hometown of Tsuru and began living with her nephew and his wife. While she hadn’t been particularly careful about her diet when living alone, her condition improved noticeably after returning to Tsuru, thanks to the well-balanced meals prepared by her nephew’s wife and the natural environment of the area.
At the age of 103, after a fall that required hospitalization, she decided to move into a nursing home, where she has lived ever since. Her family describes her as a motivated woman who enjoyed calligraphy and painting as hobbies. She was also skilled at sewing and often made her own clothes by hand.
Her family believes that her longevity can be attributed to her strong sense of independence—particularly her lifelong principle of not being a burden to others—her inner strength, her honest and free-spirited personality, and the nutritious meals and comfortable environment provided by the nursing home where she continues to live in her later years.
Following the death of 112-year-old Yoshiko Naitō of Yamanashi City on 13 November 2024, Tomi Ōno became the oldest living person in Yamanashi Prefecture.
Her age was verified by Yamanashi Prefecture, Yumi Yamamoto, and Ryohei Asano, and validated by LongeviQuest on 4 October 2025.
