Pierre Taki, an actor and member of Japanese techno-pop duo Denki Groove, on Wednesday pleaded guilty to using cocaine as his trial opened at the Tokyo District Court.
During the court hearing, prosecutors sought an 18-month prison sentence for Taki, who admitted that he had started using cocaine in his 20s and continued using it to relieve stress from his busy work life.
The trial concluded Wednesday and the court is due to hand down a ruling on June 18. His defense team requested a suspended sentence.
"There is no mistake" in the indictment, Taki, wearing a black suit, said in the courtroom packed with reporters and other people.
"I was not strong-minded enough (to resist the urge to use the drug). I apologize for causing trouble to many people," said the 52-year-old, whose real name is Masanori Taki. "I will keep my hands off drugs."
According to the indictment, Taki inhaled a small amount of cocaine at an apartment, not his home, in Tokyo around March 12. He was released after posting a bail of 4 million yen ($35,900) on April 4 after he was indicted.
His arrest has reverberated through Japan's entertainment industry, which has seen several recent drug-related arrests.
Taki is also known as the Japanese voice of snowman Olaf in the hit Disney anime movie "Frozen" and has appeared in numerous films and dramas. His group Denki Groove has performed many times abroad at music and dance festivals.
Sony Music Artists Inc. terminated its management contract with Taki following his arrest.
