Taken way back in 2008 at Hiroshima with We originally thought we were going to see a rememberance festival, but it turned out we that it was a Flower Festival, and for two days there was live music, parades, dancing etc. Awesome trip!
This was one of the many kids who were in the parades. I don't think there was any kind of uniform - just wear something red...and whatever else you can find.
