The tradition of dance has evolved gradually over the course of millennia. In Japanese, the term odoriko (踊り子, lit. "dancing girl/dancer") is a general term for girls who perform traditional dance styles.
As with many ceremonial celebrations, the dancers often wear elaborate costumes. The bright colors and flashy movements make odoriko appealing to add to fantasy works as well.
