I'm arriving at Haneda via ANA domestic flight on a Friday, then departing on an international flight from Haneda on Delta on Sunday (actually Monday, just past midnight). Upon arrival on the domestic flight, I'd like to store some luggage at the international terminal for a couple of days to pick up before checking into to the Delta flight.

I guess I'll arrive at the domestic terminal and then take a bus over to the international terminal with my luggage. But then were do I store the luggage? It seems that there are 3 facilities at the international terminal. Which one is closest to Delta check-in?

After storing the luggage, I want to catch a bus to Yokohama. I assume that is just outside the international terminal, right?
