The during the NHK-E broadcasts was female professional Ichiyo Shimizu.[1]
A total of 128 shogi professionals competed in 18 preliminary tournaments to qualify for the main tournament. These tournaments were untelevised one-day tournaments held at the Tokyo Shogi Kaikan and 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 Tomomi Kai 2-crown (Women's ōi and Kurashiki Tōka) and Manao Kagawa (Women's ōshō), which was won by Kagawa.[3] Brackets from two of the preliminary tournaments are shown below.
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 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 when the final byōyomi time control of 30 seconds per move began.[4] Sente was determined prior to each game by piece toss.
