The 62nd NHK Cup, or as it is officially known the 62nd NHK Cup TV Shogi Tournament (第62回NHK杯テレビ将棋トーナメント, dairokujūnikai enueichikeihai terebi shōgi tōnamento) was a professional shogi tournament organized by the Japan Shogi Association and sponsored by Japan's public broadcaster NHK. Play began on April 8, 2012 and ended on March 17, 2013. The 50-player single elimination tournament was won by Akira Watanabe. All of the tournament games were shown on NHK-E. The host (司会者, shikaisha) during the NHK-E broadcasts was female professional Rieko Yauchi.[1]

Participants

Preliminary tournaments

A total of 127 professional shogi players competed in 18 preliminary tournaments to qualify for the main tournament. These tournaments were non-televised one-day tournaments held at the Tokyo Shogi Kaikan and the Kansai Shogi Kaikan. 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 female professional seed was determined by a single-game playoff between Hatsumi Ueda and Tomomi Kai, which was won by Kai.

Below are the bracket from two of the preliminary tournaments.

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.[3] Sente was determined prior to each game by piece toss.

The 50 players listed below qualified for the main tournament.

Notes
  1. "W4d" stands for "Women's professional 4 dan"
  2. Players overlapping multiple categories are only listed once.
  3. The other major titleholders at the end of the previous year were Habu (ōi, and Kisei), Watanabe (Ryūō and ōza), and Kubo (ōshō).
  4. Based upon JSA 2011 calendar year rankings in the following three categories: games played, games won, and winning percentage.[4]
  5. 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.
  6. Gote (後手) refers to "the player who moves second".
  7. This was the second time that Habu had faced the same player in consecutive NHK Cup finals. Habu beat Tetsurō Itodani 5d in the finals of both the 59th and 60th NHK Cup
