Shiretoko National Park is Japan's strongest all-round wildlife destination, where brown bears, salmon rivers, sea eagles, cetaceans, seals, and drift-ice driven marine productivity create one of the world's best integrated land-and-sea ecosystems. It is strongest for travelers who want serious northern wildlife in a destination that combines dramatic scenery, strong natural-history value, and multiple ways to experience animals from land and water.
