2014 World Riichi Championship

The 2014 World Riichi Mahjong Competition was a Japanese mahjong tournament, held during July 16-20 2014 Puteaux, France, featuring invites from various nations across the globe. It is the first World Riichi Championship held. The winner of the event and the first World Champion is Hiroshi Yamai.

The vast majority of the competition consisted of players from the European Mahjong Association and those from Japan. Invites were sent to other countries, namely the United States, Canada, China, and Korea. Spots were reserved for "rest of the world" as well; Singapore and Australia took the oppoturnity. In total, the tournament featured a field of 120 players.

The concept of a world championship was presented by Martin Rep. The French riichi club TNT (Tri Nitro Tiles) offered to hold the tournament in Puteaux, near Paris, France. This proposal was accepted by the European Mahjong Association, JPML, USPML and FFMJ.

Rule modifications

A special World Riichi Rule rulebook was created for the championship. It attempts to strike a balance between the EMA rules and contemporary Japanese rules. Rules different to at least one of those include

• Kuitan ari
• Akadora nashi
• 30000 point start, tobi nashi
• Oka nashi (= "30000 point return")
• 15/5 Uma
• Kuikae nashi
• Tochuu ryuukoku nashi
• Agari yame nashi
• Nagashi mangan nashi
• Kazoe yakuman nashi
• False win declaration is a Chombo.
• False pon/kan/chi call is a Dead hand.
• Chombo is 20 points deducted from the overall score of the player. It does not effect the game it is gotten in, except for the redeal.
• 1000 point penalties for use of alternative (ex. Chinese mahjong) terminology
