Thanks for sharing!
Next month we are due to use JL001 SFO-HND, process over to HND Terminal 2 for a RON at the Haneda Excel Hotel Tokyu and depart at 10:00 AM for HKG on JL027. This all does not sound like it will be much fun, and I only hope the interterminal buses are running once we process immigration and customs (with large dive gear bags).
Last time I arrived international at Haneda was... perhaps 1966?
