Aquarian Age was a short-lived Japanese psychedelic rock band that was active in the late 1960s. The band was notable for its inclusion of two future members of the iconic progressive rock group, Happy End - Haruomi Hosono and Takashi Matsumoto. Their music often incorporated elements of folk and pop, imbued with a distinctively psychedelic sound. Despite their brief existence, they made significant contributions to the Japanese rock scene of the era, paving the way for the fusion of Western and Japanese musical elements.
