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 (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.

Preliminary tournaments

A total of 127 shogi professionals (棋士, kishi) competed in 18 preliminary tournaments to qualify for the main tournament. These tournaments were one-day tournaments held at both the Tokyo Shogi Kaikan and the Kansai Shogi Kaikan 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 seed is normally determined by a playoff or qualifying tournament among the reigning women's major titleholders. Since two of the four reigning titleholders− Kana Satomi 3 crown (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.

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. Sente was determined prior to each game by piece toss.

The 50 players listed below qualified for the main tournament.
