The group began in 1993 when brothers Kōshi (elder: vocals, rhythm guitar) and Take (younger: lead guitar) began playing together. They formed Flow in 1998, and by 2000, were joined by Keigo (vocals), Gotō (bass) and Iwasaki (drums). In 2001, the band released its first maxi single, Flow #0. In 2002, the group released two mini-albums within the same year, followed by "Okuru Kotoba", Flow's first cover single, released in January 2003, which remained on the Oricon indie chart for seven consecutive weeks and also hit No. 6 on the overall singles chart.
