Great pics! I've seen multicolores patches in the sky before but never something so isolated as this. It just goes to show something else is being added to the air (probably the result of extreme areosol concentratons) and this can't simply be explained as being caused by ice crystals. If that were the case, you would think multi-colored skies would be all too common. And if the Japanese people were the only ones to notice, this is a good example of the difference betewwn our two cultures and it shows just how dumbed down Americans have become.
