Tuesday was a national holiday and Nagano always holds firworks that evening - often in very cold weather ! The fireworks were gorgeous and ran for two hours !! They are each sponsored by a company or group, so there is a 30 second lull between each group as the sponsor is announced over loudspeakers - we watched from the main viewing grounds along the main river.
First, a few short movies (these are each several megabytes and will take a while to load):
Another Movie (Sideways, sorry)
The still images are presented here without captions, just beauty (thanks to my camera with its fireworks mode)
