Satō was born in Yawata City in Kyoto Prefecture on October 1, 1969.[1] He finished third in the 6th Elementary Student Meijin Tournament [ja] 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 [ja] in December 1982.[3]
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 [ja], 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.

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.

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]
