Clammbon (クラムボン, Kuramubon) is a Japanese musical trio, consisting of vocalist/keyboardist Ikuko Harada, bassist Mito and drummer Daisuke Itou. The group, originally formed in 1996 when the three were students of the jazz department at SHOBI College of Music [ja], 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. They left their major label and went indie in 2015.
The name Clammbon is taken from a fictional character in the Kenji Miyazawa novel Yamanashi.
