Flow is a Japanese rock band, that formed in 1998 and signed on to Sony Music Japan's Ki/oon Records label. Flow is a five-piece band made up of two vocalists, a drummer, a bassist, and a guitarist. As of March 2015, the band has released 29 singles and 9 studio albums. Their songs have been used in the opening sequences of several anime series.
The group's base was created in 1993 when brothers Kōshi (elder: vocals, occasional rhythm guitar) and Take (younger: guitar) began playing together. They formed Flow in 1998, and were eventually joined by Keigo (vocals), Gotō (bass) and Iwasaki (drums; joined 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 No. 6 on the overall singles chart. In the spring of that year, their first full-scale album Splash!!! debuted at No. 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. The songs "GO!!!" and "Re:member" both served as opening themes to the anime series Naruto, as well as "Sign" for Naruto Shippuden. "Days" was the first opening for Bones' Eureka Seven anime, and "Realize" was the opening for the PlayStation 2 video games based on the same series. Flow performed live in America for the first time in Dallas, Texas on September 2, 2006 at Anime Fest which was held at the Hyatt Hotel and Convention Center in downtown Dallas. Flow then released "Colors" in 2006, the first opening for Sunrise's original series, Code Geass: Lelouch of the Rebellion.
They provided a cover of "Cha-La Head-Cha-La" as the main theme song for the film Dragon Ball Z: Battle of Gods; the song, coupled with an insert song from the film, was released as a double A-side single on March 20, 2013, and subsequently would be featured as the opening theme for Dragon Ball video games such as Dragon Ball Z: Battle of Z and Dragon Ball XenoVerse. Flow released their eighth studio album Flow The Max!!! on March 27, 2013. Flow went to Brazil for the first time to perform at Ressacca Friends in 2013. Their single "Ai Ai Ai ni Utarete Bye Bye Bye" released on February 26, 2014 was used as the second opening to the anime Samurai Flamenco.
