Ninja Hattori-kun is a 1986 video game software developed and published by Hudson Soft for the Nintendo Family Computer exclusively in Japan.

Players take on the role of the young ninja by the name of Kanzo Hattori who is out training to impress his master.

The game features four difficulty levels of 16 side-scrolling areas that have to be completed within a time limit. Hattori has the ability to jump and throw shurikens. He can also collect scrolls that allow him to use up to eleven different ninja techniques. Hattori can get touched up to nine times by most enemy ninjas before dying. However some enemies can kill Hattori in one hit. Projectiles thrown from enemies that hit Hattori typically just stun him.
