I am tagging along with my husband on his business trip to Japan. I plan to do a lot of exploring while he's at work. I have basically 8 days to myself, but the only problem is that I have to come back to Tokyo every night by 6 or 7pm (maybe 8pm at the latest). Some of the places I plan to visit are Kyoto, Osaka, Nara, Kanazawa, Mt. Fuji, Nagano, and Nikko. Out of those places, Kyoto, Mt. Fuji & Osaka are the three places I definitely have to visit. By train all of these places are at least an hour by train from our hotel in Tokyo. How do I make the best of my time while being tied down in Tokyo?
