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 person 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 even mentioned. His name was recorded in Japan's first census of 1871.
