There is a interesting little walk to be had around Okutama area. One day last year (or was it the year before?) I took the train out with a load of camera gear to take a few pictures. Ended up walking through someones yard to get to a road and to the above station called Shiromaru which you'll find is the stop just before Okutama. There is quite a lot of walking involved if you are searching for something of interest so I suggest doing a bit of research before you embark to save your legs for the interesting stuff.
