Karateka is a 1984 martial arts action game by Jordan Mechner and is his first published game, created for the Apple II while attending Yale University. The game was published in North America by Broderbund and in Europe by Ariolasoft. Along with Karate Champ and Yie-Ar Kung Fu (both also released in 1984), Karateka is one of the earliest martial arts fighting games. It was inspired by Japanese culture (Ukiyo-e art, Akira Kurosawa films, and manga comics) and by early Disney animated films and silent pictures.
