Participants

Preliminary tournaments

A total of 139 shogi professionals competed in eighteen preliminary tournaments to qualify for the main tournament. These tournaments were one-day tournaments held at the Tokyo Shogi Kaikan and the Kansai Shogi Kaikan, but were not televised. Each tournament consisted of seven or eight players. The initial time control for each player was 20 minutes followed by a 30-second byōyomi.[2]

The women's professional seed was determined by a play-in game between Kana Satomi and Tomomi Kai, which was won by Kai.

Brackets from two of the preliminary tournaments are shown below.

Main tournament

The first time control for main tournament games was ten minutes per player. Once this was used up, a second time control of 10 one-minute periods of "thinking time" (考慮時間, kōryō jikan) began. Each player was given 30 seconds to make their move. If they did so, then no thinking time periods were used. If, however, they did not, a thinking time period began and they then had up to one minute (more specifically 59 seconds) to make a move before entering the next thinking time period. This process was repeated until a player had used all ten thinking time periods. Then, the final byōyomi time control of 30 seconds per move then began.[1] Sente was determined prior to each game by piece toss.

The 50 players listed below qualified for the main tournament.

Notes

  1. ↑ "W3d" stands for "Women's professional 3 dan".
  2. ↑ Kubo held both the Kiō and ōshō when the tournament bracket was finalized.
  3. ↑ Players overlapping multiple categories are only listed once.
  4. ↑ The other major titleholders at the end of the previous year were Habu (Meijin, ōza, and Kisei), and Watanabe (Ryūō)
  5. ↑ Based upon JSA 2010 calendar year rankings in the following three categories: games played, games won, and winning percentage.[3]
  6. ↑ Unlike in chess where moves are numbered in pairs, moves in shogi numbered individually so a game that lasts 51 moves means that sente made 26 moves and gote made 25 moves.
  7. ↑ Gote (後手) refers to "the player who moves second".
  8. ↑ Moriuchi defeated the reigning Meijin Habu four games to three to become the 69th Meijin in June 2011.[4]
  9. ↑ Hirose lost his ōi title to Habu four games to three in September 2011.[5]
  10. ↑ No other player has won the tournament more than twice in a row and only two other players besides Habu (Yasumitsu Satō and Yasuharu Oyama) have defended their title and repeated as champion
  11. ↑ Nagase was born in September 1992, and Sugai was born in April 1992
  12. ↑ A young amateur player aspiring to become a professional typically asks a more experienced professional to formally become their sponsor (i.e., teacher/mentor) and help them through the process. In some cases, the "student" may even decide to go live with their "teacher" and family.
