Sadami Matsuoka

BIOGRAPHY

Sadami Matsuoka was born in Hiroshima Prefecture, Japan, on 20 February 1914. When she was around 10 years old, she moved to Tokachi District in Hokkaido Prefecture, where she lived for the rest of her life.

The day before her 100th birthday, a birthday party was held at the day service center she had been attending since she was 87 years old. On her 100th birthday, a celebration took place at her home, and she also received a memento from Makubetsu Town. At the age of 105, she moved into a nursing home, where she lived until her passing. When asked about the secret of her longevity, she credited it to “eating every meal that is served to me with gratitude and savoring its deliciousness.”

Matsuoka passed away in Makubetsu, Hokkaido Prefecture, on 18 October 2025, at the age of 111 years and 240 days.
