Biography
Seki Inagaki was born on 4 November 1906 in Japan. She married and had a son, who himself had three children. She became the oldest woman in Hokkaido prefecture upon the death of 111-year-old Kiku Aoyama on 12 August 2018. However, Inagaki was never the oldest person in Hokkaido prefecture due to Masazo Nonaka being alive and older.

Inagaki passed away on 14 December 2018 at the age of 112 years, 40 days. Her successor as Hokkaido prefecture’s oldest woman was Tari Chiba, who was around 2.5 months younger.
