Nine Days Wonder are a Japanese rock band that formed in 1997. The group initially had a sound which was a melancholic blend of alternative rock, post hardcore and emo, but ended up becoming a solo project of frontman Kensuke Saito when the rest of the group departed in 2004, and the sound of Nine Days Wonder thus evolved into being more of an electropop influenced style. Nine Days Wonder still remain active today as 9dw, with their initial emo sound practically non-existant.
