About Jiroemon Kimura
Jiroemon Kimura was a Japanese supercentenarian who was the verified oldest living person between Dina Manfredini's death on 17 December 2012 and his own death at age 116 years and 54 days on 12 June 2013. Kimura became the oldest verified living man in the world on 25 September 2011 at the age of 114, upon the death of Peru's Horacio Celi Mendoza, and later also the oldest man in history whose lifespan is verified on 28 December 2012, when he surpassed the age of Christian Mortensen (1882–1998). He is the only verified man who has lived to age 116, and one of only six men known to be the oldest living person. After thorough research, including conducting family interviews and searching official records, the authors verified Kimura's age and date of birth. Kimura's nephew Tamotsu Miyake said his uncle's birthday was 19 March, but that this had been mistakenly recorded as 19 April in 1955 when records from neighbouring towns were consolidated and redone.
