Early life, amateur shogi and apprenticeship

Maruyama was born in Kisarazu, Chiba on September 5, 1970.[1] He won the 9th Junior High School Student Shogi Meijin Tournament [ja] in 1984,[2] and the following year entered the Japan Shogi Association's apprentice school at the rank of 6-kyū as a protegee of shogi professional Yūji Sase [ja]. He was promoted to the rank of 1-dan in 1986 and achieved professional status and the rank of 4-dan in April 1990.[3]

Shogi professional

Maruyama's first tournament championship as a professional came in came in 1994 when he defeated Masataka Gōda 2 games to none to win the 25th Shinjin-Ō [ja] tournament.[3][4] Maruyama successfully defended his championship the following year by defeating Kōichi Fukaura 2 games to 1 in the 26th Shinjin-Ō match which made him the first person to win the tournament in consecutive years.[4][5] Maruyama, however, was unable to repeat his success for a third consecutive year when he lost the 27th Shinjin-Ō match 2 games to 1 to Takeshi Fujii in 1996.[4]

Maruyama's first appearance in a major title match came in 1999 when he challenged Yoshiharu Habu for the 47th Ōza title.[3] Maruyama lost the match 3 games to 1.[6]

On December 8, 2023, Maruyama became the tenth professional shogi player overall and the first since July 2017 to reach 1000 wins in official games when he defeated Kōichi Fukaura in a Eiō tournament preliminary round game. Maruyama qualified for the JSA's "Special Shogi Honor Award" for reaching this milestone. His career record at the time of the victory was 1000 wins and 600 losses for a winning percentage of 0.625.[7][8] That same month, Maruyama defeated Sōta Fujii to win the 31st Ginga-sen [ja]. The victory gave Maruyama his first Ginga-sen championship, and it also was the first defeat for Fujii in a tournament final since obtaining 8-crown status in September 2023. The championship game was actually played on November 1, 2023, but the final result was not made public until the game was broadcast on December 23.[9]
