Overview: The Miyagawa River originates in the pristine heights of Mount Odaigahara, in the center of the Kii Peninsula, and flows down to Ise Bay. Because its lower reaches run past Ise Jingu (the Grand Shrine of Ise), the river is also often known as the "River of the Gods." The Miyagawa is also renowned for its water quality, which is among the clearest in the country. On this episode of Journeys in Japan, Peter Skov hikes through the spectacular Osugidani valley, before arriving at the source of this sacred waterway.
