Early life
Watanabe was born on April 23, 1984, in Katsushika, Tokyo.[1] He learned how to play shogi from his father, who was an amateur 5-dan ranked player.[2][3] He won the Elementary School Student Meijin Tournament in 1994 as a fourth-grade student at Hokizuka Elementary School.[4] He was the first fourth-grade winner in the history of the tournament.[3]
That same year Watanabe took the entrance exam for the Japan Shogi Association's apprentice school. Part of his test was a game against future female professional Sayuri Takabe, who was member of the apprentice school at the time. The entire game was played at an extremely fast pace, with Watanabe winning in less than two minutes.[3] Watanabe passed the entrance exam and entered the Apprentice School as a 6-kyū protegee of shogi professional Kazuharu Shoshi.[1]
Shogi professional
Watanabe was promoted to the rank of professional 4-dan on April 1, 2000 at the age of 15 after winning the 26th 3-dan league (October 1999 to March 2000) with a record of 13 wins and 5 losses, thus becoming the fourth junior high school student after Hifumi Katō, Kōji Tanigawa and Yoshiharu Habu to become a shogi professional.[5]
Watanabe made his first appearance in a major title match in October 2003 when he challenged Habu for the Ōza title. Watanabe led the match 2 games to 1 before Habu won the last two games to defend his title.[6] Even though he lost the match, Watanabe was called "The man who made Habu shake" (羽生を震えさせた男 habu wo furuesaseta otoko) because Habu's hand visibly shook when making the winning move during the deciding fifth game.[2][3]
In December 2004, Watanabe won his first major title when he defeated the defending Ryūō title holder Toshiyuki Moriuchi 4 games to 3. Moriuchi was also the reigning Meijin and Ōshō title holder at the time. Watanabe was 20 years 8 months old at the time, thus making him the third youngest major title holder ever.[2][7]
In 2005, Watanabe defended his Ryūō title for the first time when he defeated challenger Kazuki Kimura 4 games to 0. As a result, Watanabe became the youngest person ever to be promoted to the rank of 9-dan at the age of twenty-one years and seven months.[3]
In March 2007, Watanabe defeated computer shogi program Bonanza to win the first JSA-sanctioned game between a computer shogi program and a top shogi professional. Bonanza was the reigning World Computer Shogi Champion, while Watanabe was the reigning Ryūō title holder.[8]
Watanabe became the first person to qualify for the Lifetime Ryūō title in December 2008 after winning the title for the fifth consecutive time. He defeated Habu (the reigning Meijin, Ōza, Ōshō, and Kisei title holder) 4 games to 3 to win the 21st Ryūō title match. Habu won the first three games, but Watanabe came back to win the final four to defend his title, and become the first player ever to win a 7-game major title match after losing the first three games. The match was billed as the "Winner Becomes the First Lifetime Ryūō Match" because a win by Habu would have been his seventh Ryūō title overall, thus making him the first Lifetime Ryūō.[9][10][11]
In 2011, Watanabe challenged Toshiaki Kubo for the 36th Kiō title, but lost the match 3 games to 1.[12] Two years later in 2013, Watanabe challenged Masataka Gōda for the 38th Kio title. Watanabe defeated Gōda to not only win his first Kiō title, but also to become only the eighth player in history to become a "3-crown": a player who simultaneously holds three major titles.[13] Watanabe successfully defended his Kiō title in 2014 against Hiroyuki Miura,[14] in 2015 against Habu,[15] in 2016 against Amahiko Satō[16] and in 2017 against Shōta Chida.[17] Watanabe's victory over Chida was his fifth consecutive over all, making him only the second player ever to qualify for the Lifetime Kiō title.[18]
In 2012–2013, Watanabe won the 62nd Ōshō Challenger League tournament with a record of 6 wins and 0 losses to advance to the title match against Yasumitsu Satō.[19] In the title match, Watanabe defeated Satō 4 games to 1 to win the Osho title for the first time.[20] The following year, Watanabe faced challenger Habu in the 63rd Ōshō title match, and successfully defended his title by the score of 4 games to 3.[21] Watanabe, however, was unable to defend his title for a second consecutive year when he lost the 64th Ōshō title in seven games to challenger Gōda.[22]
Personal life
In May 2004, Watanabe married Megumi Ina and the couple's eldest was born during the summer that same year. Ina is the younger sister of shogi professional Yūsuke Ina and is also a mangaka. The couple met when Ina was an apprentice female shogi professional and became friends due to their shared interest in tsumeshogi.[23][24][25]
Watanabe is a fan of Keiba as well as professional soccer, even traveling to overseas to attend games. He obtained a class 4 soccer referee license because of his son's interest the game and has served as head referee at some elementary school games.[23][26][27] Watanabe also started the Japan Shogi Association's futsal club.[28]
