This month, the Japan Professional Mahjong League debuted a new tournament, the Mahjong Japan Series. This series gathers 12 players who have either won a major title in 2014, voted by the public during a live stream or were recommended by JPML. The 12 players are:
Fujita Susumu (Saikyosen)
Masayoshi Ara (Mahjong Grand Prix MAX)
Naoya Maeda (Hououi)
Hiroshi Yamai (World Riichi Championship)
Hideki Sakurai (10 Dan)
Jun Murakami (Saikoui)
Taro Suzuki (Janou)
Ooi Takaharu (RMU League)
Yuudai Maehara (JPML’s recommended pro)
Masayuki Katayama (JPML’s recommended celebrity)
Naoki Setokuma (1st Fan pick)
Satoshi Fujisaki (2nd Fan pick)
What’s fascinating about this is JPML don’t normally work with other pro leagues (with the only big exceptions being WRC and Saikyousen), and it’s the first time the WRC rules have been used in Japan by a professional league.

Inspired by Shogi’s ‘Denousen’, a niconico sponsored AI vs professional tournament, Tsunoda has posted on Tenhou’s blog a few months ago that he wanted to hold similar tournaments.
While bots were previously banned from Tenhou, with permission from Tsunoda, programmers may now allow their bots to play in joukyuu, and must also wait for Tsunoda’s permission before letting it run loose in tokujou if it reaches that level.
Bots have a special prefix “ⓝ”, which stands for Nonplayer, to distinguish them from players. There’s currently one bot that I know of, ⓝ爆打. It peaked at around 5D R1850~ but has recently fell to 4D R1780~ and Tsunoda is still unsure if he should allow it to enter tokujou. Naoki Mizukami, The author of 爆打, has wrote a few papers (in Japanese) about Mahjong AI, these can be read on his site. All of the bots games can be viewed at https://twitter.com/ai_mahjong
xkime previously subbed episode 1 of the live action adaptation of Shinasaka’s Tohai manga, since then he has moved on to subbing it on Rakuten’s (free) streaming service viki and has just finished subbing the final episode of season 1.
Season 2 is also available here some of the episodes have been subbed by someone else, but I think the subtitles need a bit of editing before they become watchable.
Suji are a popular defense strategy; so popular, in fact, that suji traps are an effective anti-defense. We would like to increase the yomi level and create an anti-anti-defense by identifying when suji traps are likely. Are there situations in which suji are more dangerous? Are they really traps, or are they just incidental discards?
Prominent authors actually disagree on this. Some claim that suji discarded after riichi are more dangerous, while others claim that suji discarded before riichi are more dangerous. The general agreement is that the tile discarded immediately upon declaring riichi is dangerous.
Who’s right? Do you think there’s a difference? Using the Tenhou game logs database, we can examine riichi hands and their discards to finally answer this question.
