Overcoming negative perceptions, we lead the healthy popularization of Mahjong as a mind sport.
Based on a systematic approach, we are a global mind sport organization promoting Korean Mahjong to the world.
History of Korean Mahjong
Introduction from China
Believed to have been introduced during the early Joseon Dynasty, though detailed records do not remain.
Spread via Japan
During the late Joseon period, a simplified form was introduced for faster gameplay, but it gradually deteriorated into gambling.
Leap as a Mind Sport
Shedding the stigma of gambling, it is being reborn as a healthy intellectual sport.
