Biography

鳥星雨 (ちょうせいう or とりせいう) is an amateur Riichi Mahjong player who currently administers the Northwestern University Riichi Mahjong (NURM) club, based in Evanston, IL, USA. He founded the club in April 2018, and continues to play a large role in the management of the club, despite his graduation and overseas employment. An alumnus of Northwestern University and Waseda University, 鳥星雨 has connections with both the North American scene and the Japanese scene. He currently resides in Suwon, South Korea.

鳥星雨 plays as 鳥星雨 on Tenhou, where he shares a healthy rivalry with his fellow clubmate and close friend YuukiTheFlash. He is also a former regular club member at Chicago Area Mahjong and Waseda Mahjong Club. He still often plays on Tenhou with members from his former clubs, and runs the NURM weekly Friday night Tenhou meetings, hosted within the club's Discord Server.

鳥星雨 loves watching mahjong more than he does playing it. This leads to him organizing his own tournaments, and watching videos of the pros more than actually playing on Tenhou. However, he does enjoy the game on a casual and competitive level. For 鳥星雨, there is no better place for mahjong than a Shinjuku jansou. The jansou is his home, and the auto-table is his bread and butter.

Outside of mahjong, 鳥星雨 is avid fan of the 東方Project series of games, and the 同人 arrangements of its music. He also enjoys reading the 咲-Saki- manga and its derivative works. In his free time, he converses with others using 日本語 or 한국말.

Playstyle

鳥星雨 has a digital playstyle, centered entirely on maximizing expected values based on outcome and probability. This factors in various elements, such as the value of your hand and probability of winning it, but also the probability of dealing into an opponent. He sees mahjong as a model of game theory, where there is a probability distribution over drawn tiles, and a set of strategies for each player. While prior beliefs about these strategies can be ascertained by playing the same players consistently, on Tenhou L0, the only way to attain this information is to read discards well. This is the area that 鳥星雨 is looking to improve upon the most.

鳥星雨 likes to watch his favorite professional players and model his playstyle off of them. His favorite pros include 魚谷佑美 (Uotani Yuumi), 二階戸亜紀 (Nikaido Aki), 茅森早香 (Kayamori Sayaka), and 近藤誠一 (Kondou Seiichi). In his free time, he looks at videos of professional play, and tries to analyze what they are doing better than him. In particular, he is quite excited about the start of Mリーグ, and you can probably guess what his favorite team is.

Finally, 鳥星雨 firmly opposes playing with beginner players who do not know proper defensive strategies. Games with one or more of these beginner players disproportionately overvalue aggressive play, which 鳥星雨 finds incredibly boring after a while. Instead, 鳥星雨 is often times very happy to play open hand games with these players to teach them proper defensive strategy so that they can play better in real games.
