If you do stop by Okada’s museum, Oshino Hakkai is worth checking out (or vice-versa). The eight seas (hakkai) in the name refer to the eight ponds fed by underground springs. An open-air museum has been put up around the largest of the ponds, with thatched-roof huts done up in a traditional style. The views from Oshino Hakkai of Mount Fuji are impressive, especially with the olde tyme cottages in the foreground—weather permitting, of course.
