Awa odori is part of the Bon festivities, which are held to welcome one's ancestors back to this world for a few days. Though Bon dances are usually performed in a circle, Awa odori participants march in a straight line. The dancers are grouped into teams called ren, which are usually made up several dozen dancers. They march through the streets in unison to music performed on the shamisen, flute, drums, and bells singing "Odoru aho ni miru aho; onaji aho nara odoranya son son!" (It's a fool who dances and a fool who watches; if both are fools, you might as well dance!).
