Fireball Over Abiko?
At 22:18 Japan time, as I was walking home, I saw something I can't quite explain. A bright light came over a house that was blocking my view to the west, split in two, then forked a third. The first two were bluish-white, the third orange. It looked like a Roman candle, but didn't show any ballistic arc, just the path of a meteor. It petered out overhead, near Mars, having covered about 30 degrees of sky. It was brighter than Mars, but not impossibly bright, comparable to or slightly brighter than the brightest meteors I've seen.
This is in Abiko, northeast of Tokyo, at roughly 35.88N 140.03E.
