Kushiro Shitsugen Marsh is a vast and relatively flat coastal wetland in Hokkaido, formed by the outflow of the Kushiro River into the Pacific. Spanning roughly 350 square kilometers, it features broad reed beds, shallow bays, and tidal pools that fluctuate with the tide. The marsh is most famous as a wintering ground and spring migration stop for Tancho (Japanese cranes), making wildlife viewing and guided crane tours core activities. Facilities include elevated boardwalk trails, visitor centers, and boat access for marshland safaris. Seasonal considerations: expect cold temperatures and snow in winter, while spring and fall are ideal for birdwatching; summers are wetter and milder. Nearby amenities are limited; plan for guidedTours, local ryokans, and outdoor gear. Kushiro Shitsugen blends ecological significance with accessible visitor experiences, offering an immersive look at Japan's high-latitude wetlands.
