The Shakotan Peninsula juts out into the Sea of Japan. The brilliant hue of the surrounding waters is called "Shakotan Blue," while its sheer cliffs create an impressive landscape. The program host takes a clear-bottomed kayak out into the sea with a local guide to take in the scenery from the water. They row their kayaks into a cave on the cliff, where the water glows a mysterious blue color. Also, witness some rare footage of chum salmon, making their difficult journey from river to sea.
