Mahjong Kaguyahime Sono2

Mahjong Kaguyahime Sono2 (麻雀かぐや姫 その2 / Mahjong Princess Kaguya Part 2) is an adult-themed Japanese arcade medal game originally developed and published by Miki Syouji in August 1989.

Players bet credits or medals on the outcome of the hand. Higher bets tie into the game's reward structure, which traditionally includes anime-style strip-tease visual progressions featuring Princess Kaguya as the player wins hands.
