The Riot subidiary of Telenet Japan was best known for employing graphic artist and later director Eiji Kikuchi, and music composer Michiko Naruke.
It came into existence in 1991 when Telenet Japan was expanding in the country. However, because Telenet was starting to lose sales in 1993, it went through extensive restructuring which resulted in the closing of a few subsidiaries, including the Riot subsidiary. Some staff involved were transferred to another subsidiary, Wolfteam.
