Mina Kitagawa was born in Echigawa (now Aisho), Shiga prefecture, Japan on 3 November 1905. Her father was a farmer, and her husband worked for Japanese National Railways. They moved from one place to another due to his job, before eventually settling in Hikone, Shiga, where they rented about 2,500 square meters of land to grow rice and vegetables.
Kitagawa continued to work as a farmer until she was 100 years old. In 2017, she moved into a nursing home in Hikone, Shiga. She reportedly enjoyed knitting and handcrafts, and her favorite food was beef.
Kitagawa died on 19 December 2020 at the age of 115 years, 46 days.
