Tomoki started as a DJ in his native country Japan in 1999. His original blend of sweet and aggressive avours quickly marked him out as one of the most promising young Japanese DJs of his generation.He went on to hold residencies at some of Japan’s top clubs, playing alongside top international DJs such as Derrick May, Doc Martin, Lil'Louis, Timmy Regisford, Joe Claussell, Danny Krivit, Blaze, Larry Heard, Daniel Wang, Kerri Chandler, Jerome Sydenham, Ron Trent and Osunlade. Regular mix sessions for the radio stations Shibuya FM and Osaka Cable only added to what was already fast becoming a cult following and the nation-wide commercial release of a successful series of mix albums on tape (“the Groove Café Series”) was well received by both fans and critics alike, further cementing his reputation as one of the top young DJ’s in Japan’s underground house scene.

In 2004 he moved to London where he has continued as a DJ in top venues such as Ministory of Sound, Turnmills, the Cross, The Key, AKA, 54, the Notting Hill Arts Club, Herbal and Cargo. Within a few months of arrival at its new home of AKA Bar, Holic was already a resounding success, rapidly becoming one of London’s busiest Thursday night parties. Hosted by his own DJ collective “the Geisha Disco Boyz” and supported by “Kikiorix”, guest DJ’s have included Andrew Weatherall, X-Press2, Jimpster, Jim Masters, Pete Heller, Terry Farley, Spektrum and Milton Jackson. The trademark from Tomoki is a fusion of deep, tech, electro, minimal and soulful sound.

After his debut single "Where We Were" in Plastic City in the beginning of 2010, he comes back with the single called "Frustration". The Original Mix is already known from the Plastic City Radio Show, Season Three album. The single comes up with two brand new remixes from "Sebastien Russell" and "From P60".
