Fireworks and devils! Cool festival event in Noboribetsu in Hokkaido were Oni (Japanese devils) carry tubes that shoot fiery sparks high into the sky. The origin of the festival goes back to the misty past of a few years ago in an effort to drum up tourism. Works for me.
Oni Hanabi goes on for about two months from June to the second week of August every Thursday and Friday starting at 8:30pm and lasting about 30 minutes.
