I will have a chance to arrive NRT on Fri, 11 Feb, at 9 AM, and depart NRT about 3 PM, Sat, Feb 12. I have previously done the 8 hr layover trip to Narita city, and am thinking Tokyo for 1 nite this time. What is the easiest, most fool-proof way for a non-Japanese-speaking gaijin to get a train ride to a Tokyo station, stay in a hotel within walking distance of that train stop, and have enough neighborhood to walk around in and be entertained? Looking for the least opportunity to get lost, as I am worried it might be easy - I've seen the Tokyo train map. Wow, how does a native, much less me, figure that thing out? Appreciate any advice that will give me the confidence to try it. Thanks.
