Hello! I booked a flight after Christmas where I have a 20 hour stopover. The problem is that I'm landing at Haneda at 23:55, and I'd prefer not staying at a hotel at the airport. Is there any sort of night bus that goes past 00:40? I don't have a destination in Tokyo yet booked (last time I stayed in Asakusa and Shinjuku) but I'm looking for a ryoken for the night if possible. Any help would be appreciated.
