To replace the musicians, the band added acquaintances, such as drummer Satoshi Yamaguchi and bassist Yusuke Takeda. Radwimps returned from hiatus in March 2004, though Kei Asō, Yūsuke Saiki, and Akio Shibafumi did not rejoin the group. The following August, after a guest appearance at the Yokohama High School Music Festival, the band went on hiatus for Noda and other members to focus on their school exams. The band released their debut album, Radwimps, in July through independent label Newtraxx, featuring songs they wrote in middle school. Following this single, Radwimps toured the Yokohama area, including a performance as the sole act at Yokohama's Club 24West. "Moshi mo" was released as the band's debut single in May 2003, with 10,000 copies pressed and sold for 100 yen each. In September and August 2002, Radwimps partook in the Yokohama High School Music Festival and eventually won the grand prize for the competition with the song "Moshi mo". At this point, guitarist Akira Kuwahara dropped out of high school in order to focus on the band. The band's activities were initially centred on Yokohama, and their first performance took place on BB Street in Kannai district on 5 February 2002. Lead vocalist Yojiro Noda first became interested in music after hearing Oasis in middle school, when he would try to remember the guitar chords and sing to Oasis songs. The five original members had been friends since middle school. Radwimps formed in 2001 in Kanagawa, Japan during their first year of high school.
