Naoto Onishi is a Japanese 4A (offstring) competitor. He won the 4A division at the 2015 World Yo-Yo Contest in Tokyo, ahead of Takumi Yasumoto in second and Rei Iwakura in third. The same year he won 4A at the Asia Pacific Yo-Yo Championships and placed second at the Japan National Yo-Yo Contest, where JYYF records him using the Yoyorecreation Aeronaut.
