They made their debut on Avex Trax subsidiary, avex tune, under the guidance of producer Akio Togashi on June 11, 1997 with "Feelin' Good -It's Paradise". As one of the few male groups unassociated with Johnny's Entertainment, they were the first to gain major popularity reaching their peak in 2001 with the release of Da Best of Da Pump. On April 7, 2006, Shinobu formally left the group following a hiatus due to a drunk driving incident in 2005. The group went on an unofficial hiatus at the end of 2006.
