It takes 90 minutes from Sakata to Tobishima, the only isolated island of Yamagata Prefecture. It is 39 km off Sakata Port and still retains unsullied natural beauty. It takes about two hours to go around the island. There are no traffic lights. As a stopping point for migratory birds, it is often crowded with migratory birds that fly north from the continent in spring and others that fly south in winter. You can enjoy fishing and sea bathing. Because a warm current flows nearby, the island is relatively warm and covered by evergreen broad-leaved trees throughout the year. It is famous for a delicious soup stock made from flying fish.
