Karate Champ, known in Japan as Karate Dō (空手道, "The Way of the Empty Hand") is a 1984 arcade game developed by Technōs Japan for Data East.

The player assumes the role of a karate competitor and fights against another player or the computer. Using two joysticks, players can execute a number of moves.

Gameplay consists of a two dimensional fight between Karate characters wearing white and red gi, followed by various bonus rounds for the successful player. This pattern repeats itself in the next, more challenging round set against a new background. Unlike most later fighter-type games, there are no health bar or hit points. A hit successfully landed ends the round and earns the player or his opponent either one point or half point (along with a numeric score for the top ten but this has no effect on winning a match per se). The first to score two points is the winner. The game also featured some early speech synthesis, in which the judge would call out such phrases as "Fight!" or "Winner!" It's also spoken in Japanese in the Japanese version.
