Rin Aoyagi was born in the town of Toyotama (now part of Tsushima City), Nagasaki Prefecture, Japan, on 5 October 1878. She was born in a farming family.
In February 1907, she married Iwaji Aoyagi, with whom she had four sons. Her husband passed away in 1941.
In 1984, she moved into a special nursing home for the elderly, “Asao no oka”. She had 11 grandchildren. In March 1991, she developed a fever and became very weak in April.
Rin Aoyagi passed away in Mitsushima (now part of Tsushima City), Nagasaki Prefecture, Japan, at 10:15 AM of 14 May 1991, at the age of 112 years, 221 days.
In October 1988, she celebrated her 110th birthday, becoming the second person in Nagasaki Prefecture to reach the age of 110, the first one being Taki Sugimoto (1859–1969), whose age has not been validated.
In September 1990, the Japan’s Ministry of Health, Labour, and Welfare (MHLW) published the National List of the Elderly, and Mrs. Aoyagi was listed as the second-oldest living resident of Japan, behind Waka Shirahama of Miyakonojo, Miyazaki Prefecture.
Her age was verified by the MHLW, as well as Yumi Yamamoto, and validated by LongeviQuest on 20 May 2023.
