Calcifier, it looks like you'll be fine--are you on AA? We may end up being on the same flight
I didn't stay in any kind of hotel last night, and am certainly not a meteorologist, but that graphic on Goo Net makes it look like the center will be right over Tokyo Sunday evening

My friends are all saying that typhoons usually slow down, and hang a hard right when they get near land here, but I would have thought the real meteorologists would have considered that when plotting the trajectory.
