In March 1989, the band started its Taboo tour. At this point they had stopped putting their hair up so much, and Sakurai had even given up on dyeing his and let it be black. The tour was scheduled to run through May, but it was cancelled abruptly when Imai was arrested for LSD possession. The incident was covered in newspapers and tabloids at the time, but since, the band has kept it very quiet. Buck-Tick went on hiatus and Imai had to appear at a court hearing, which was attended by hundreds of concerned fans and was covered on television.
