Power Soukoban(POWER 倉庫番?) is a variation of Sokoban released for the Super Famicom in Japan on January 1, 1999. It was published by Nintendo and developed by Atelier Double. The player controls a demon as he moves one or more rocks into holes in order to complete each level.
Power Soukoban begins in a dungeon cell, in which the main character, an unnamed oni, and several other creatures from Japanese mythology, are held prisoner. An elder demon explains that warp holes have opened up between Japan and the West, and that Japan has subsequently become invaded and occupied by Western ghosts. The oni is entrusted to plug up all the holes with rocks (hence the Soukoban gameplay), thus restoring peace to Japan. Throughout the game, all of the friendly characters are mythical Japanese creatures, such as kappa, kitsune, and hitotsume-kozo. On the other hand, the bosses include such Western monsters as Frankenstein, Medusa, and Dracula, the final boss. The nationalist content of the story, in which Japan and the West are explicitly put into conflict with each other, may have contributed to the game not being released outside of Japan.
