Seems like fraud, this was taken from wiki:

On November 4, 2008, Komuro was arrested and charged with fraud, for taking ¥500,000,000 in exchange for a promise to sell to a Hyogo-based investor the copyright to his songs, which he had already sold to somebody else (which was Avex Group Holdings according to reports).[4][5][6] Reportedly, he planned to use the money to pay a portion of his ex-wife's alimony.[7][8] He admitted the fraud at his trial in January 2009.[9]
In March 2009 Matsuura Masato, president of the Avex Group Holdings, recovered the losses for the plaintiff, paid him extra ¥100 million in compensation and a further ¥48 million in delay damages. Matsuura also stated that Komuro will work at Avex in a company position directly under his control.[10]
On May 11, 2009, Komuro received a suspended three-year prison sentence. According to the sentencing judge, Komuro's acceptance of responsibility and the fact that restitution had been made greatly influenced the final sentence, and further went on to state that no good to society would come from Komuro's imprisonment.
