Heath joined the band in 1992, replacing Taiji's position as the band's bassist. Many says that Heath's skill was that below of Taiji, but I don't know *I'm sorry Heath* because of all instruments in X Japan, I always have problem listening to the bass. Heath personality, I don't really know much about. He was not often in the limelight, though he did some solos in some concerts before. Pata says that Heath was often regarded as the 'younger rowdy son' in the band, hee ^^.  Even though he was seldom heard of, Heath was an important member of the band nonetheless. After the disbandment of X Japan, Heath and Pata formed the band Dope Headz with some other people. I don't know what Heath is doing now but he is definitely pursuing his solo career. Best of luck, Heath! ^__^
