The group's base was created in 1993 when brothers Kohshi (elder: vocals) and Take (younger: guitar) began playing together. They formed Flow in 1998, and were eventually ed by Keigo (vocals), Got's (bass) and Iwasaki (drums; ed in 2000). In 2001, the band released its first maxi single, "Flow #0". The group then released two mini-albums within the same year, both of which took nationwide indie charts by storm. "Okuru Kotoba", Flow's first cover single, was released in January 2003. It remained on the Oricon indie chart for seven consecutive weeks and also hit an impressive #6 on the overall singles chart. In the spring of that year, their first full-scale album Splash!!! debuted at #2. In July 2003, Flow released the single "Blaster" on a major label, Ki/oon Records. In April 2004, they released "Go!!!", which stayed on the Oricon Top 10 Chart for three weeks. In May 2004, Flow released their first major album Game.

A string of singles followed and in July 2005 the band released its third album, Golden Coast. Since the release of Golden Coast, Flow has released two singles with new A-sides, but one of these ("Around the World/Kandata") was a double A-side release. World End released in 2008. Their song Go!!! was played at the 2008 Summer Olympics in the baseball game between Japan and Australia.
