clammbon is a Japanese trio known for blending jazz-influenced chords with J-Pop and electronic elements into something distinctly quirky. The group formed back in 1996 when Ikuko Harada (vocals, keyboards), Mito (bass), and Itou Daisuke (drums) were all studying at Tokyo Music and Media Arts Shogi. They landed a major label deal with Warner Music Japan in 1999.

The band's name comes from a character in Kenji Miyazawa's short story "Yamanashi."
