I a couple of weeks I'll be making my 12th trip to Japan in a little over 3 years for work. I'll be spending quite a bit of time in Tokyo, which I've been to many times now. My wife will be joining me for 1 week (her 4th time) and I'd like to take her someplace new and different. We are tired of the usual Tokyo sites (Meiji, Tokyo parks, Asakusa, temples, etc) and would rather find someplace near Tokyo (no more than about 60 minutes by train from central Tokyo) that offers either beautiful landscape, something unusual (an interesting museum or garden for example), or small town Japan feel. For reference, we have both spent time in Tsukuba before. We both like it for its quiet feel and tons of green space.
