The latest trial of rock musician Okamura Yasuyuki (45), who already has two convictions for the use of stimulant drugs, began at the Tokyo District Court yesterday. He was arrested in February for the use of the drugs at his Shinjuku, Tokyo home and is likely to face prison time for a third drug-related offense. Prosecutors are looking for a sentence of two and a half years, while lawyers for the defendant asked for leniency. The court will hand down a verdict on May 8. The singer, whose heyday was in the late 1980s, likes to invite comparisons with Prince and prides himself on his dancing and ability to play multiple instruments.
