The Shiretoko Peninsula lies at the far northeastern tip of Hokkaido, Japan's northernmost prefecture. It is an area of remarkable natural beauty, with a vibrant diversity of wildlife both on land and in the sea. Since 2005, it has been designated as a UNESCO World Heritage Site. It is one of Japan's most unexplored regions, and one of the few places in the world where bears have an undisturbed natural habitat. For the Hokkaido brown bears living there, the mountains, rivers and virgin forests are an unspoiled paradise. On this episode of Journeys in Japan, Dean Newcombe travels to Shiretoko to discover its pristine environment.
