Chiyono Hasegawa ( 20 November 1896 – 2 December 2011) was a Japanese supercentenarian. Aged 115 years 12 days at the time of her death, she was the oldest verified person in Japan (since the death of Kama Chinen on 2 May 2010) and the oldest verified person in Asia.
She was the 2nd oldest verified living person in the world behind American woman Besse Cooper.
At the time of her death, Hasegawa was one of only 26 people verified to have surpassed a 115th birthday.
In September 2008 on Senior Citizen’s Day, Chiyono Hasegawa, then 111, and her 61-year-old grandson were visited by Governor Furukawa of Saga Prefecture.
On 2 May 2010, the day she became the oldest verified living Japanese person, Hasegawa attended a ceremony held at her nursing home which announced her new record.
