Cause of death
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 first verified by Guinness World Records, who titled him the oldest man ever, but Guinness have in recent years backed away from their previous statement; in the Guinness World Records Book 2012, Christian Mortensen is titled "the oldest verified man ever", and Izumi is not mentioned.
Death and controversy over age
After a brief hospitalization, Izumi died of pneumonia at 21:15 JST on February 21, 1986. Izumi was the longest holder of the "oldest living person" title. 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. Also in the Guinness World Records Book 2011, it 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 Izumi 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 (about 4.5 years less than Izumi's claimed age).
