Sounds like Hakone is a little bit easier to navigate, which might be ideal since I will not have a car. It also sounds like Hakone has a little better advantage for the "nature" standpoint because of Mt. Fuji. Any particular Fuji-based ideas you suggest I do while I'm in Hakone? Perhaps a Mt. Fuji viewpoint? Is it close enough to Fuji to do some hiking? Any particular hiking trails or hiking tours?
