In 2011, likely following the passing of 106-year-old Inao Chiba (Japanese: 千葉稲男) of Tome on February 19, he became the oldest living man in Miyagi Prefecture.

Sometime at the age of 107, he became the oldest man to ever live in Miyagi Prefecture.

In September 2015, he celebrated his 110th birthday, becoming the first male supercentenarian in Miyagi Prefecture.

On 29 October 2016, following the death of Japan’s oldest living man of the time, Masamitsu Yoshida of Tokyo, he became the second-oldest living man in Japan, after Masazo Nonaka. Since Nonaka survived him, Sasaki never became the oldest living man in Japan.

His age was verified by Japan’s Ministry of Health, Labour, and Welfare (MHLW), as well as Ryohei Asano and Tzen Wei Tseng, and validated by LongeviQuest on 10 June 2023.
