62nd NHK Cup (shogi)
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(ja) (日本将棋連盟 Nihon Shōgi Renmei?), or JSA, and sponsored by Japan's public broadcaster NHK (日本放送協会 the Nippon Hōsō Kyōkai?). Play began on April 8, 2012 and ended on March 17, 2013. The 50-player single elimination tournament was won by Akira Wantanabe. All of the tournament games were shown on NHK-E. The host (司会者 shikaisha?) during the NHK-E broadcasts was women's professional (女流棋士 joryūkishi?) Rieko Yauchi.
A total of 127 shogi professionals (棋士 kishi?)[a] competed in 18 preliminary tournaments to qualify for the main tournament. These tournaments were one-day tournaments held at both the Tokyo Shogi Kaikan(ja) and the Kansai Shogi Kaikan(ja) and 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. A "piece toss" (振り駒 furigoma?) was performed prior to each game to determine "the player who moves first" (先手 sente?).
The women's professional[b] seed is normally determined by a playoff or qualifying tournament among the reigning women's major titleholders.[c] Since two of the four reigning titleholders− Kana Satomi 3 crown[d] (Women's Meijin, Women's ōshō, and Kurashiki Tōka) and Momoko Katō (Women's ōza)−were also "apprentice professionals" (奨励会員 shōreikaiin?), they were ineligible to qualify; therefore, the women's professional seed was determined by a single-game playoff between Hatsumi Ueda (Mynavi Open) and Tomomi Kai (Women's ōi), which was won by Kai.[e]
Below are the bracket from two of the preliminary tournaments.
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. Sente was determined prior to each game by piece toss.
The 50 players listed below qualified for the main tournament.
- "No." represents the bracket position of the player in their respective block and "Rank/Title" represents the rank or title(s) held by the player when the original bracket was finalized. A dan/kyū (段級 dankyū?) grading system is used for ranking players.

The final tournament bracket is shown below.
- Sente won 26 (a little more than 53%) of the 49 games.
- The average number of moves per main tournament game was 112. The most moves played in a single game was 184 (Rd. 1, Chiba 6d vs. Suzuki 8d) while the fewest number of moves played was 67 (Rd. 1, Nagase 4d vs. Kamiya 7d).
- There were no replays resulting from repetition (千日手 sennichite?) or impasse (持将棋 jishōgi?), and there were no disqualifications due to illegal moves or time forfeits.
- The age breakdown (age at start of the tournament) for the players who qualified was as follows: 10–19 years old, 3 players; 20–29 years old, 10 players; 30–39 years old, 19 players; 40–49 years old, 16 players; 50–59 years old, 2 players. The oldest player was Michio Takahashi 9d (51 years old) and the youngest player was Kōru Abe 4d (17 years old).
- The word kishi refers to shogi players officially awarded professional status by the JSA. Only amateurs strong enough to join and graduate from the JSA's "apprentice professional training school" (奨励会 shōreikai?) are awarded kishi status and the rank of professional 4 dan.
- Women's professionals are recognized by the JSA, but they are only granted kishi status upon completion of the shōrekai. To date, there have been women (including some currently active women's professionals) who have successfully qualified for the shōreikai, but so far not one has successfully graduated. Only three women have made it as far as 1 dan in the shōreikai and of those three only one has made it as far as 3 dan.
- There are six women's major titles: the Women's Meijin, the Women's ōshō, the Women's ōi, the Woman's ōza, the Kurashiki Tōka, and the Mynavi Women's Open.
- The Japanese character 冠 means "crown" and is commonly used as an honorific suffix attached to the names of multiple major titleholders. Therefore, "3 crown" (三冠 sankan?) means that the player currently holds three major titles. Players holding only one major title are commonly referred to by their title. Non major titleholders are referred to by their rank (dan).
- Kai lost her Women's ōi title to Satomi 3 crown in May 2012.
- "W4d" stands for "Women's professional 4 dan". Women's professionals are ranked differently than regular professionals (kishi) by the JSA. The strongest women's professionals are considered to be roughly equivalent to 1 dan or 2 dan apprentice professionals in playing strength.
- Players overlapping multiple categories are only listed once.
- The other major titleholders at the end of the previous year were Habu (ōi, and Kisei), Watanabe (Ryūō and ōza), and Kubo (ōshō). Kubo actually lost ōshō title to Y. Satō in the weeks leading up to the tournament, but by then the bracket had been set.
- Based upon JSA 2011 calendar year rankings in the following three categories: games played, games won, and winning percentage.
- 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.
- Gote (後手?) refers to "the player who moves second".
- 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
