The island of Tobishima lies off the coast of Yamagata Prefecture in the Japan Sea. It is about 10 kilometers in circumference, and is dotted with long-established fishing villages. These days, it has a population of about 200 people. Tobishima is a port of call for migratory birds and an important breeding ground for black-tailed gulls. Its rich natural environment attracts many anglers and birdwatchers. In 2016 Tobishima was designated as a geopark by the Japan Geopark Committee. On this edition of Journeys in Japan, John Moore explores Tobishima, meets the people living here, and learns about their self-sufficient lifestyle.
