Earthshaker is a Japanese heavy metal band that was formed in 1978 in Osaka. One of the first Japanese metal bands, they steered toward a poppier sound on later albums and dropped from worldwide view, preferring to record and tour in their home country. After a successful run, they broke up in 1994, but returned five years later and remain active.
The quintet from the nineties is still together. An early incarnation of the band included Minoru Niihara as singer.
