Clammbon (クラムボン Kuramubon?) is a Japanese musical trio, consisting of vocalist/keyboardist Ikuko Harada, bassist Mito and drummer Itou Daisuke. The group, originally formed in 1996 when the three were students at Tokyo Music and Media Arts Shobi, made their major label debut on Warner Music Japan three years later. Their music is characterized by their quirky sound combining jazzy chord progressions with J-Pop and electronica influences.
The name Clammbon is taken from a fictional character in a short story by Kenji Miyazawa.
