Matsuura was born in Japan on 2 January 1912. At some point, she had children.
In January 2011, at the age of 99, Matsuura suffered a stroke but made a full recovery after receiving prompt treatment and undergoing rehabilitation. Later that year, she was visited by city officials who presented her with two congratulatory letters in celebration of Respect for the Aged Day—one from then-Prime Minister Yoshihiko Noda and another from the city mayor.
Chiyo Matsuura passed away in Asahikawa City, Hokkaido Prefecture, Japan, on 30 January 2023, at the age of 111 years, 28 days.
Matsuura was first known to researchers during Keiro no hi (Respect for the Aged Day) in September 2020, but the first time she was noted for her longevity was a blog post about her 102nd birthday in 2014.
Matsuura’s grandson, Kouta, would post on Facebook on her birthday every year from 2020 to 2023. In 2022, he congratulated her for living in five Japanese eras (Meiji, Taishō, Shōwa, Heisei, and Reiwa).
In September 2022, she was reported as the sixth-oldest living person in Hokkaido Prefecture.
Her age was verified by Japan’s Ministry of Health, Labour, and Welfare (MHLW), as well as Yu Li, Bogdan Solyanikov, and Takehiro Shibuya, and validated by LongeviQuest on 4 December 2023.
