Mahjong Gakuen Toumasou Shirou Toujou

Mahjong Gakuen Toumasou Shirou Toujou (麻雀学園 東間宗四郎登場) is a mahjong game developed by Sankindo for the PC Engine and published in Japan by Face in 1989. The game features pixelated nudity. When playing female opponents, winning subsequent hands of mahjong causes them to undress, similar to strip poker. The game also has male opponents which the player simply beats up instead after every successful game.

It is the first undressing mahjong game ever officially released for sale at home (not including unlicensed software), but the depiction of exposing womens' body parts was seen as a problem, and it was not re-released after the first production. As a result, it was sold at a high price in second-hand stores. By pressing the Select button during the game, the screen would switch to a screen depicting an RPG.

Touma Soushirou Toujou is based upon the 1989 arcade game Mahjong Gakuen 2 Gakuen-chou No Fukushuu, which is the follow-up to the original 1988 arcade game Mahjong Gakuen. Outcry over its salacious content forced Face to reconfigure the game as Mahjong Gakuen Touma Shoushirou Toujou Mild the subsequent year, which removed the nudity and replaced it with skimpy swimwear.
