If you are interested in watching mahjong-centric Anime, both Akagi
and three seasons Saki (“Saki”, “Saki Side-A”, “Saki Nationals”) are available on Crunchyroll.
A large number of tournaments are available to view legally on various video sites.
Mahjong MAX Tournaments are available on the JPML’s Youtube Channel. 5-hanchan events, no kan or ura dora, so tight, low-scoring nailbiters the whole way through!
The Queen’s Cup, by San Group, is available on their YouTube channel as well. See how the game changes with red 3s (making chanta-type hands that much stronger)!
Tsuchida’s Mahjong Lessons
Tsuchida Koushou, the offense-style mahjong player that focuses on toitsu (pairs) for his attacks, has a video repository filled with lessons on digital and occult techniques.
