Overview (history, characteristics, attractions)
Kushiro Marsh is one of Japan's largest wetlands, located in eastern Hokkaido, and is centered around Kushiro City. The vast marshland was formed by post-glacial topographical changes and years of vegetation accumulation, creating a unique landscape with large and small meandering rivers. A rare ecosystem has been preserved here, and it is home to a variety of migratory birds, wetland plants, and insects, including the Japanese crane. Since the 1980s, conservation efforts have been underway, including registration under the Ramsar Convention and designation as a national park (Kushiro Marsh National Park), making it a popular tourist destination for nature observation, photography, river rafting, and other activities.
Highlights
- View from the observation deck: You can enjoy a panoramic view of the marshland from Hosooka Observatory and Kushiro City Marsh Observatory. The appearance of the marshland changes dramatically depending on the light in the early morning or evening.
- Meandering Kushiro RiverThe river meandering through the marshland makes for a great photo opportunity, and the bird's-eye view from Hosooka Observatory is particularly famous.
- Crane observation: In winter, you have a better chance of seeing red-crowned cranes when you observe them feeding (under protective scrutiny) around Tsurui Village and other areas. The basic rule is to observe quietly.
- Boat and canoe experience: You can experience a leisurely journey through the marshland on a Kushiro River boat tour. The marshland seen from the water has a different charm than when viewed from land.
- Seasonal Nature: The landscape changes with the seasons, with flowers and insects in spring and summer, fresh greenery in summer, autumn leaves and migratory birds in autumn, and snowy scenery and red-crowned cranes in winter.
