Bonze Adventure, known in Japan as Jigoku Meguri(地獄めぐり,lit. "Hell Tour"?), is a 1988 platformarcade game that was later ported for the PC Engine by Taito. The player controls a Buddhistmonk, Bonze Kackremboh. His weapons are Buddhist prayer beads, called "mala" beads, which can be powered up until they become almost as large as the player. The monk battles snakes, giant eyeballs, ghosts and other enemy creatures.
Emma, the lord of the underworld mentioned in the introduction screen, is Emma-O, the Japanese Buddhist god of the Underworld. Traditionally, Emma-O keeps track of a mortal's life and decides the punishment of those sent to the Underworld in accordance with Buddhist law.
