Chiyonofuji no Ooichou is a sumo wrestling sports title developed by Arc System Works and released for the Famicom in 1990. Named after the legendary Yokozuna Chiyonofuji, the game allows players to create and customize their own sumo wrestler with unique facial features in a charming 'chibi' art style. The goal is to climb the ranks of professional sumo to reach the ultimate title of Yokozuna. Gameplay features a strategic stamina and power meter system, requiring players to balance defense and offense. It also includes a tutorial mode for beginners to master the various pushing and throwing techniques. Interestingly, this is an early work from the developers who would later create the famous Guilty Gear series, making it a piece of gaming history for fans of Japanese sports culture.
