Masaki Ito

is a Japanese citizen and trampoline gymnast, representing his nation at international competitions.

At the age of four Ito began to learn swimming and gymnastics, including artistic gymnastics and trampoline, but by the age of six, following the advice of his instructor, began to focus on the trampoline. He enjoyed the trampoline because it felt like flying. He competed at world championships, including at the 2007, 2009, 2010, 2011, 2013, 2014 and 2015 Trampoline World Championships. Ito was unable to train for six months in 2013 because of injuries to his wrist, and incurred a back injury in 2015.
