Kazuki Kimura

Kazuki Kimura (木村 一基) is a Japanese professional shogi player ranked 9-dan. He is a former Ōi title holder. He is also the oldest player to win a major title for the first time.

Early life, amateur shogi and apprenticeship
Kimura was born in Yotsukaidō, Chiba Prefecture on June 23, 1973. He learned how to play shogi at a friend's house when he was in kindergarten, and started regularly going to a local shogi club when he was a second-grade elementary school student.

Kimura first met his future mentor shogi professional Yūji Sase when the two played a 2-piece handicap game. Kimura soon began taking lessons from Sase at his house, where he occasionally played practice games against Hiroe Nakai, who was another one of Sase's students. In 1985, he advanced to the quarterfinals of the 10th Elementary Student Meijin Tournament as sixth-grade elementary school student, and later that same year entered the Japan Shogi Association's apprentice school under the guidance of Sase.

At first, Kimura progressed fairly quickly and was promoted to the rank of 3-dan in the fall of 1990 when he was an eleventh-grade high school student, but it took more than six years before he was able to obtain professional status and the rank of 4-dan in April 1997.

Shogi professional
Kimura became the 52nd shogi professional to reach 600 career wins on December 21, 2017.

In June 2019, Kimura defeated Yoshiharu Habu to earn the right to challenge Masayuki Toyoshima for the 60th Ōi title. In the title match against Toyoshima, Kimura lost the first two games before coming back to tie the score at two wins apiece. Toyoshima won Game 5 and needed just one more win to defend his title; Kimura, however, won the last two games to win the match 4 games to 3. The victory not only gave Kimura his first major title, but it also made him the oldest first time winner of a major title at the age of 46 years and 3 months, breaking the record of 37 years and 6 months set by Michio Ariyoshi in 1973.

In June–August 2020, Kimura was unable to defend his Ōi title against Sōta Fujii, losing the 61st Ōi title match 4 games to none.

In September–October 2021, Kimura challenged Takuya Nagase for the 69th Ōza title, but lost the match 3 games to 1.
