Overview: The Minami-Izu area lies on the southern tip of the Izu Peninsula, in Shizuoka Prefecture. It is a popular destination for those who love marine sports, such as surfing, snorkeling and fishing. On this edition of Journeys in Japan, Michael Keida explores this rugged coastline. He catches some waves on his surf board. He rents a snorkel, mask and fins so he can look at the subtropical fish that live in the shallow sheltered waters. He goes out angling on a fishing boat, and then enjoys the seafood he catches for dinner at his lodging. The highlight of his trip is when he goes diving off Mikomoto-shima, an island nine kilometers off the coast of Minami-Izu. At this world-famous dive spot, he is lucky enough to see a huge group of hammerheads, a distinctive species of shark that can grow over four meters long.
