Kōryū Tadaharu
Kōryū Tadaharu (光龍 忠晴, born 4 February 1984) is a Mongolian former sumo wrestler from Ulan Bator. His highest rank was "maegashira" 11. He was forced to retire from sumo in 2011 after being found guilty of match-fixing. Early life and sumo background. Munkh-Orgil Erdene's father was a motocross rider, and he followed in his footsteps by participating in the sport from ages 10–16. He was also active in basketball and his team won the national high school first and second years' championship. Later, the Hakkaku stable coach, former "yokozuna" Hokutoumi came to Mongolia looking  for new wrestlers. A competition was held and Erdene did sufficiently well, along with two other tryouts, later wrestlers Hoshihikari and Hoshizakura to gain acceptance into the stable. However, at the time, each stable was limited to two foreign wrestlers each, so the other two went to Hakkaku stable and Erdene was allowed to enter another stable, Hanakago. He came to Japan to join this stable and entered professional sumo in November 2000. The first character of his "shikona" or ring name was at the behest of his coach, who on his first visit to Mongolia, found the sun of  the high plains of Mongolia bright and glorious. Career. He did not manage to achieve "sekitori" promotion to "jūryō" until January 2007. He was the first member of his stable to reach sumo's second highest division since it was re-established by the former "sekiwake" Daijuyama in 1992. After about a year and a half in "jūryō", he gained promotion to "makuuchi," but was demoted the next tournament after winning only three bouts. A convincing 10-5 record at "jūryō" #5 in the next tournament put him right back in the top division, where he would last two tournaments . After about a year in "jūryō", his reappearance in "makuuchi" in January 2010 following another 10-5 performance was his third promotion to the top division. However, a poor 3-12 record saw him demoted to "jūryō" once again for March. He returned to "makuuchi" after an 11-4 record which included a playoff for the "jūryō" championship, but his fifth attempt at a winning score in the top division in the May tournament proved unsuccessful. Nevertheless, he was back in "makuuchi" once again in September 2010. In the following November tournament he finally managed a winning record in his  sixth tournament in the top division. Retirement from sumo. Koryu was one of 23 wrestlers found guilty of fixing the result of bouts after an investigation by the Japan Sumo Association, and he was forced to retire in April 2011. Fighting style. Koryu was an "oshi-sumo" specialist, preferring pushing and thrusting techniques. The Sumo Association lists "tsuppari", a series of rapid thrusts to the chest, as his favourite. His most common winning "kimarite" was "oshidashi", or push out. Family. Kōryū was married in 2010, with the reception taking place in January 2011. The couple have a daughter, born in  April 2010. His mother's brother in law is the uncle of fellow Mongolian wrestler Shōtenrō. Career record.
