Base Ball Bear (ベースボールベアー) is a four piece Japanese rock band signed to EMI Music Japan and managed by Sony Music Artists. The group was formed in 2002 while in high school and as something of a one-off lark, managed to stick together and become one of the more prominent bands in the modern Japanese music scene. Base Ball Bear debuted with the mini-album Yugata Generation under the independent label BLITZ PIA RECORDS.
