In November 2015 he asked Joshua Chetty, a player he had previously coached, to make a corrupt approach to a fellow player during an ITF Futures tournament in Stellenbosch, South Africa. The player was offered $2,000 to underperform in a singles match and $600 in a doubles match.
Chetty received a lifetime ban last September. The following month, Mitsuhashi directly approached a different player at a tournament in Lagos, Nigeria to ask him to fix aspects of a match. He also illegally placed 76 bets on tennis matches between October and November 2015 and refused to cooperate with the TIU investigation, both of which are separate offences. Mitsuhashi achieved a career-high singles ranking of 295 in 2009. He was ranked 1,997th at the time of his offences.
