Early life

Satō was born in Yawata City in Kyoto Prefecture on October 1, 1969.[1] He finished third in the 6th Elementary Student Meijin Tournament in 1981.[2] His experience in the tournament led him to want become a shogi professional, and he entered the Kansai branch of the Japan Shogi Association's apprentice school at the rank of 6-kyū in December 1982 as a protegee of shogi professional Kaishū Tanaka in December 1982.[3]

Shogi professional

Satō's first appearance a major title match was in 1990 as the challenger to Kōji Tanigawa for the 31st Ōi title, but he lost the match 4 games to 3.[3][4] That same year, he won his first tournament as a professional when he defeated Toshiyuki Moriuchi to win the 9th Hayazashi Shinei Tournament, a quick-play type tournament for young players under the age of thirty. He repeated as champion the following year when he won the 10th Hayazashi Shinei Tournament when he defeated Taku Morishita in the final.[3][5][6]

In 1993, Satō challenged Yoshiharu Habu for the 6th Ryūō title and won the match 4 games to 2 for his first major title. The same two players met in the title matches for the 7th Ryūō (1994) and 8th Ryūō (1995). Challenger Habu was able to recapture his title by the score of 4 games to 2 in 1994 and then defend it by the same score in 1995.[3][7]

In 1997, Satō challenged Habu for the 38th Ōi title Habu, but lost the match by the score of 4 games to 1.[8] The two met once again the following year for the 39th Ōi title, but Habu defended his title by the score 4 games to 2.[8] That same year, Satō was the challenger to Habu for the 24th Kiō title, but lost the match 3 games to 0.[9] Satō once again challenged Habu for the Kiō title in 2001. Satō won the first game of the 27th Kiō match, but Habu then won the next three games to defend his title.[10]

In just his second year in Meijin Class A, Satō earned the right to challenge Tanigawa for the 56th Meijin title (1998) by defeating Habu in a one-game playoff after both players finished league play with a record of 6 wins and 3 losses.[11] Satō then proceeded to defeat Tanigawa 4 games to 3 to win the Meijin title for the first time. The following year, Satō and Tanigawa met again for the 57th Meijin title (1999), with Satō defending his title by the score of 4 games to 3. Satō, however, was unable to successfully defend his title for the third consecutive year when he lost to Tadahisa Maruyama 4 games to 3 in the 58th Meijin title match (200).[12]

Satō was the challenger in the 47th Ōshō (1997) and 49th Ōshō (1999) title matches against Habu, but lost by the scores of 4 games to 1 and 4 games to 0, respectively.[13] In 2002, Satō finished the 51st Ōshō challenger league play undefeated with six wins to once again challenge to Habu for the title. Sato won the first two games of the match and then split the next four to win the match 4 games to 2,[14][15] thus ending his title match losing streak to Habu at eight.[3] The following year, however, Habu was successful in retaking the title from Satō, winning the 52nd Ōshō match 4 games to 0.[16] Satō and Habu met again in 55th Ōshō (2006) and 56th Ōshō (2007) title matches with Habu defending his title each time by the score of 4 games to 3.[17][18]

In 2007, Satō defeated Toshiyuki Moriuchi (the reigning Meijin at the time) to win the 56th NHK Cup Shogi TV tournament.[19] He defeated Daisuke Suzuki the following year to defend his title and become just the third player ever to win the tournament in consecutive years, with the championship game between the two being the first NHK shogi tournament game ever to be broadcast live on TV.[20] Satō won the tournament for a third time in 2017.[21]

Satō became the ninth professional player to record 1000 victories in official games when he defeated Akihito Hirose in a Meijin Class A game on July 28, 2017. Satō is the first player to accomplish such a feat since Habu did so in 2007.[22][23]

Playing style

He was known to use a lot of jōseki positions as a young player, but since 2005 he has often opted for choosing to play creatively with the standard strategies. His new move 5. P-96 for Cheerful Central Rook has been widely adopted by many professional players. From a young age he has been known for the depth of his reading, which is called his "minute" or "meticulous" style, and of which is said that he can "read a billion of three-move series in a second".

JSA president

Satō served as the chairman of the Shogi Professional Players' Association from April 2011 until January 2017.[24][25] He announced his candidacy for the JSA's board of directors on January 19, 2017, a day after Kōji Tanigawa announced his resignation as JSA president to accept responsibility for the 29th Ryūō challenger controversy.[26][27]

Satō was elected to the JSA's Board of Directors at an emergency meeting of the organization's members on February 6, 2017, and was later chosen by the board at a meeting held the same day to serve out the remainder of Tanigawa's term as JSA president.[28][29] He was re-elected as president for a full two-year term at the JSA's general meeting on May 29, 2017,[30] and re-elected once again for another two-year term in June 2019.[31]
