Earthshaker were one of a handful of Japanese hard/melodic rock band formed in 1978 in Tokyo. Their earlier music was also influenced by heavy metal, but the band 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 are still going strong today. Remarkably, the original quartet from the first album are still together.
