Genpei Touma Den

Genpei ToumaDen is a beat 'em up arcade game that was released by Namco in 1986 only in Japan. It runs on Namco System 86 hardware.

Introduction
The player must take control of a real Japanese samurai, Taira no Kagekiyo, who fell at the battle of Dan-no-ura in 1185. In the game, he is resurrected and has to fight other characters who actually existed such as Minamoto no Yoshitsune and Saito Musashibo Benkei over the Imperial Regalia of Japan, as well as defeat his arch-enemy Minamoto no Yoritomo.

The game also features the Sanzu River, a place believed in Japanese Buddhism to separate "the current life" and "the afterlife", resembling the concept of Underworld or Hell. Therefore, mythological characters such as Emma-O, God of the Underworld, and Sun Goddess Amaterasu appear in the game.
