I know there's a currently active thread about a 10-hour layover at NRT, but I have a 13-hour layover at HND (arriving at 13:55 on a Wed. and departing at 1:00 the next morning) and am wondering if that changes folks' recommendations. I've never been to Tokyo (we were 5 minutes from landing at NRT in March when the earthquake hit; after spending 5 hours on the tarmac at a US Airforce base, followed by a night sleeping on the floor at HND, we ended up spending all of our time in Osaka and Kyoto), so I'd love to go into the city (preferably exploring the city and mingling with the people rather than going to a museum or the like). What do you recommend?
