Otoyo Town in Kochi Prefecture is located in the center of the Shikoku Mountain Range. More than 80% of its land is covered with forest. This mountain community is the only place that produces a special variety of tea, called Goishi-cha. Goishi-cha is a traditional specialty of Otoyo, which has been passed down in the community for over 400 years. Otoyo also lies on the Yoshino River, which is one of the 3 rivers with the wildest, strongest currents in Japan -- and also the birthplace of rafting in the country. On this episode of Journeys in Japan, we meet the people of Otoya, who have kept alive their traditions over the centuries, as well as newcomers who have moved into the community, lured by the beauty of its natural environment.
