Saikouisen Nihon Pro Mahjong Kyoukai (最高位戦日本プロ麻雀協会) is a professional mahjong organization with the longest history in Japan.

Saikouisen USA is a branch of Saikouisen Nihon Pro Mahjong Kyoukai, similar to Saikouisen Kansai, Saikouisen Hokkaido and other branches within Japan.

Our goal is to spread competitive mahjong within the United States by hosting the professional mahjong test in English, providing professional and amateur leagues and tournaments using the Saikouisen rules, and much more.
