Shigechiyo Izumi (泉 重千代, Izumi Shigechiyo, 1880? (or June 29, 1865) – February 21, 1986) was a Japanese centenarian who was titled the oldest living person after the death of Niwa Kawamoto, also from Japan. His case was initially verified by Guinness World Records, who titled him the oldest man ever, but Guinness later withdrew their verification and in the Guinness World Records Book 2012 Christian Mortensen is titled "the oldest verified man ever" (since superseded by Jiroemon Kimura, see below) and Izumi is not mentioned.
Izumi drank brown sugar shōchū (a Japanese alcoholic beverage often distilled from barley or rice), and took up smoking at age 70.
After a brief hospitalization, Izumi died of pneumonia at 21:15 JST on February 21, 1986. He was one of only two people (the other being Jeanne Calment) verified to have lived past their 120th birthday, although subsequent research has discounted the verification. In April 1987, 14 months after Izumi's death, the Department of Epidemiology at the Tokyo Metropolitan Institute of Gerontology reported that research into Izumi's family registration records indicated Izumi might have been 105 when he died. The Guinness World Records Book 2011 states that "The birth certificate submitted as evidence might actually belong to his older brother, who died at a young age; if the family used Shigechiyo as a 'necronym'—that is, gave him his dead brother's name, as the new research suggests—this means his final age was 105 years old, not 120."
The oldest undisputed case of male longevity is Jiroemon Kimura (also from Japan; lived April 19, 1897–June 12, 2013), who died at age 116 years and 54 days.
