By far one of the best weekend retreats from Tokyo I've ever had. The train ride out there is pretty short and there are tons of hotels with both western and Japanese style rooms. The onsens in this area really are stellar. Just keep in mind that Nikko is not exactly a well-kept secret...places book up pretty far in advance. But if you go to JTB and get a lucky last minute booking, you can save a ton of cash on your trip, and still score an awesome travel package.
