In terms of transport there is nothing as far as I remember unless you've pre-booked something. You have the option of sitting outside or inside by the check in desks (air conditioned), with some free wifi available here and there. If you are there until sunrise it is also possible to take a walk over to ladder beach (20-30 minutes walk IIRC), although I recommend carefully studying a map/google earth before doing that.

Overall one of the friendlier US entry points, but I've had mixed experiences, such as when I was sent to a sadistically slow secondary because I looked like I was in a rush, which shouldn't be a too shocking behavior for a passenger who is stepping off a flight that arrived 1 hour late. I also have to stand in the visitor line which tends to be slow, especially if you arrive at the end of the afternoon rush from Japan when the wait may be as much as one hour.
