In 1993, while still in X Japan, Pata released his first self-titled solo album, which featured many veteran American musicians such as Tommy Aldridge, Tim Bogert, Mike Porcaro and James Christian. His second, Raised on Rock, was released two years later and again featured Christian, as well as Chuck Wright and Ken Mary. He also played at a number of concerts for fellow X Japan lead guitarist Hide’s solo career from 1994 to 1998. A year after X Japan’s breakup, he formed P.A.F. (standing for “Patent Applied For”, named after the PAF guitar pickups) with singer NoB. In about one year’s time they released: two albums, one mini album, one live album and two singles. For the 1999 Hide tribute album, Tribute Spirits, Pata teamed up with X Japan bassist Heath and former Spread Beaver percussionist/programmer I.N.A. to cover the X Japan song “Celebration”. He would reunite with them again in 2000 when they formed Dope HEADz, adding vocalist Jo:Ya. They released two singles and an album, when in 2002 they recruited new singer Shame and released Planet of Dope. Soon after its release they would cease activity.
