Former Japanese player Junn Mitsuhashi was banned for life from tennis and fined $50,000 by the Tennis Integrity Unit on Tuesday for trying to fix matches and betting on the sport.

Mitsuhashi, 27, also failed to cooperate with TIU's investigation, which is an offense in its own right, tennis' anti-corruption body said.

According to the Japan Tennis Association, Mitsuhashi is the first Japanese to be punished by the TIU. The JTA said he became the national junior high school champion in 2004, and partnered with current world No. 9 Kei Nishikori in doubles at the 2005 Junior Davis Cup.

Mitsuhashi, who had a reputation as a troublemaker since his teens, turned pro in November 2007, touring the lower-tier circuits. His highest singles world ranking was 295th in 2009, and was at No. 1,997 at the end of 2015 -- the last year he was registered with the JTA.

TIU reported that Mitsuhashi asked a player he previously coached, Joshua Chetty, in November 2015 to make a corrupt approach to a fellow competitor at an International Tennis Federation tournament in South Africa.

The amount Mitsuhashi offered to underperform was $2,000 for singles and $600 for doubles, according to the report.

In December 2015, Mitsuhashi directly approached a different player to fix a match at another ITF event in Nigeria.

Mitsuhashi was found guilty of betting on 76 matches between October and November 2015.

"Things like this absolutely cannot happen. We can only continue what we have been doing (to prevent corruption)," senior JTA official Hajime Takahashi said.
