Iyama Yuta (井山 裕太)

Iyama Yuta (井山 裕太, Iyama Yūta, b. 24 May 1989) is a Japanese, professional 9-dan of the Nihon Kiin Kansai branch. He began as a renowned child prodigy and has became one of the most dominant players in contemporary Japanese go. In 2013 and again in 2015 he held six of the seven major Japanese titles.[1] In 2016 he finally managed to hold all seven titles simultaneously. He is married to professional shogi player Io Murota.[2]

Iyama was born on May 24th, 1989. At the age of five he learned Go after watching his dad play on the computer. In about a year he became a Japanese 3-dan and soon after become a pupil of Ishii Kunio 9-dan. Together they would play over 1,000 online games. During this period he began to be known as a child prodigy due to his quick improvement and number of wins in youth tournaments.[3]

In October 1998, Iyama became an insei. He challenged for a professional spot in 2001, but lost to Kohei Kawada. The following year (2002) he tried again and this time earned his professional status -- becoming the fifth youngest professional.[4] At the age of 16, he established the current records for youngest professional to hold a Japanese professional open title (the Agon Cup), and the youngest to reach the rank of 7-dan.[5] In 2008, he was promoted to 8-dan for becoming the challenger for the 33rd Meijin title; and in 2009 to 9-dan for winning the 34th Meijin title.[6][7] At this point he became the youngest Japanese professional to hold one of seven big Japanese titles and the youngest Japanese 9-dan.[8]

In May of 2012, Iyama married professional shogi player Io Murota, who happens to share his same birth date.[9]

In November 2012, after winning the 60th Oza from Cho U, Iyama simultaneously held five of the major seven domestic titles (the Gosei, Honinbo, Judan, Oza and Tengen).

In March 2013, Iyama won the 37th Kisei, making him the youngest person to have held all seven titles, the youngest to simultaneously hold six of the seven major titles at once, the youngest Kisei winner at 23-years and 9-months (the previous record was Cho Chikun at 26-year and 5-months), and third person have held all seven titles (after Cho Chikun and Cho U respectively).[1] Recapturing the Meijin title in October 2013 meant that Iyama held every one of the seven major titles during the same year, though not simultaneously.

In April 2016 Iyama won the 54th Judan, finally becoming the first player ever to hold all seven major titles simultaneously.

Style

In 2008, John Power said, "Iyama plays thickly, waits for the opponent to attack, then tries to take the initiative with his counterattack."[10]

An Younggil has said several things of Iyama:

"Iyama is also very good at local fighting. His play isn't typical Japanese style. He plays rather severely and sharply."[14]

"...he doesn't generally start fighting, but rather waits for the right time to fight." & "Iyama is also a genuine fighter."[15]

"Iyama’s style of play is thick and solid."[16]

"Iyama prefers a fighting game, as he's confident at fighting and still quite young. In general, younger players tend to be keener on fighting."[17]

"Iyama's not worried about a fighting game, but it looks like he still prefers this sort of territorial game compared to other top players from China and Korea."[18]

"He seems to like to play solidly, and doesn't mind a large moyo game."[19]

Discussion

  • Anonymous: Not to take anything away from Iyama's performance but it was harder to reach 9-dan under the old oteai ranking system. Promotions to 9-dan by recommendation did occur, e.g. Go Seigen in 1950 after his successes in 10 game matches and Ishida Yoshio in 1974 after becoming Meijin Honinbo, but such promotions were very rare.
    • Hyperpape: It was actually easier to make 9 dan, but harder to do so quickly (it took at least 8 years). The new promotion system is more stringent, but allows an exceptionally talented player like Iyama to reach 9 dan more quickly, if he can prove himself in the major tournaments.
  • mmKALLL: The person Iyama lost to in the exam, Kawada Kohei, was - according to the senseis page - born in 1992 and became shodan in 2001. Is there a mistake there?
    • tapir: Yes. The birthday is wrong. (Obuchi Kotaro was born that day.)
