Overview:Islands -- stringing along 3,500 kilometers, north to south, in the Pacific -- so narrow that no point is ever far from the sea. Coastlines alone spanning 35,000 kilometers… We dip under the waves to explore the Japanese archipelago's epic world of water. Tagging along with Michael Keida, and on one dive with Bonnie Waycott, we delight in tropical and temperate zone marine life, corals, 2 shark species and a friendly Asian sheepshead wrasse. Michael reminisces in the studio about his adventures with narrator Bill Sullivan.
