Overview: Cape Soya lies at the northernmost tip of Hokkaido Island. Located at a latitude of 45° North, the landscape in this area is very different from the rest of Japan - and it is sometimes known as the "Ireland of Japan." In this edition of Journeys in Japan, John Moore explores the wild nature of Japan's northernmost tip. He sees for himself the bounty of the ocean, even in this harsh climate. And he tries his hand at fly fishing, in the hopes that he may come face to face with the mysterious itou fish.
