In the 7th century, two types of dance were introduced to Japan from China: Bugaku and Sangaku. Bugaku was entertainment for the aristocracy, with the dance movements being very serene and quiet. Sangaku however, was very lively. Sangaku did not just involve dance, but also encompassed such attractions as music, puppetry, and acrobatics. It lent itself more to the working people of Japan. Buygaku still exists and now consists of court dances. Sangaku does not exist as a separate form, but, as Japan has done with other bits of Chinese culture, been assimilated into Japanese culture. Sangaku became Sarugaku, a lively form of dance which was performed at various social functions. Sarugaku eventually, around the 10th century, became Noh theatre, a combination of dance and theatre.
