Kazuhito Iimura (飯村数人) is a Japanese speedcuber. He specializes in Square-1, for which he greatly improved the unofficial average record. Although he only competed once officially in 2008, he set the Square-1 average world record of 16.62 seconds.
Kazuhito also created the Iimura mod for the Square-1, which increases corner-cutting by shaving down edges. A similar design is found in many modern 3x3s such as F-2, A-V, and the GuHong.
