I headed over to the All Okinawa Eisa Festival tonight (Sunday) to see the unique activities of this very popular event. Eisa is a form of Okinawan dance that recoginized the end of summer and honors passed ancestors. All the cities around Okinawa have local competitions and send their best to this festival to compete in 3 days of Eisa dances. I'm including a couple photos and a video (I apologize for the quality of the video, but I had my big 70-200mm lens on my camera at the time and holding 5 lbs of camera and lens over my head can be tough).
Here's a link to an article about Eisa: http://www.japanupdate.com/?id=7062
These painted characters are a fun and unique part of the dance.
Drums are a major component of the music for the dance
Last entry is the video, showing a clip of what the Eisa Dance is like.
