"Future Ninja"), is a side scrolling beat 'em up arcade video game, released by Namco in 1988 exclusively in Japan.

[1][2] Character designs and directing of the film were done by Keita Amemiya of Zeiram and Kamen Rider fame.

The player controls Mirai Ninja, who must fight various enemies and bosses by rapidly throwing shurikens at them (and slashing them with his sword at close range).

His life meter uses Kanji for the numbers; this was previously done in Namco's earlier Japan-only title, Genpei Tōma Den (1986), for the score display.

In Japan, Game Machine listed Mirai Ninja on their January 1, 1989 issue as being the tenth most-successful table arcade unit of the month.
