I've arrived and am happily tucked into my hotel room by the airport. The flight really wasn't bad - the seat was pretty comfortable and there was an empty seat between me and the guy in the window seat.
I started feeling a cold coming on a few days ago. That really worried me for the flight. But it wasn't too bad. I think I felt worse when I got off the plane. Better off the plane than on the plane!
As we landed in Tokyo, I was so excited to see sakura from the plane. There's some near my hotel, too!
