Eisa dancing is performed on the last day of the three-day Obon celebration to bid farewell to the ancestors’ spirits (michi-junee). To most Uchinanchu (Okinawans), this day is a most chim-dondon (exciting) occasion. Young men and women travel around residential streets and business areas dancing eisa, accompanied by drums, folk songs, chants and whistling. Eisa was originally performed so that people could give the spirits a good send-off. Around 30 young men and women dance eisa at any one time, singing, chanting and playing drums to the strains of a sanshin.
