HND is actually in Tokyo, as opposed to NRT, which is 60km (40 miles) out.

I was living in Tokyo when NRT opened, and everyone complained about it, especially since there were no trains that went all the way (and wouldn't be for a couple of years), and the terminal where the direct bus left from was in an inconvenient location.

HND is a brief monorail ride from the Yamanote commuter train line that circles the central city.
