Guida
The Watarase Floodplain is a massive reservoir area originally developed to manage water levels from the Tone River. Today, it serves as a vital sanctuary where rich natural environments are carefully preserved. The area is characterized by its vast, swaying reed beds and serene waterfront landscapes. It is widely recognized as a premier habitat for various wild birds, making it an ideal destination for nature observation and outdoor recreation. Visitors can enjoy a wide range of activities, from tranquil birdwatching to high-energy sky sports and water sports.
Historically, this area was engineered as a flood control facility to manage the waters of the Tone River, acting as a temporary storage basin during heavy rainfall. The region also holds significant historical weight, with connections to the Ashio Copper Mine incident and the legacy of the social reformer Tanaka Shozo. In recent years, the focus has shifted toward a harmonious coexistence between nature conservation and modern recreation, ensuring the landscape remains a protected yet accessible natural treasure.
The changing seasons bring different wonders to the Watarase Floodplain. The vast reed beds transform with the weather, offering a dynamic view of nature's cycles. A notable feature is the artificial nesting towers installed by Oyama City and Tochigi City, which attract species like the Oriental White Stork. Beyond the ground, the sky and water are also active: you might see hot air balloons and paragliders soaring above, or canoes and yachts gliding across the water, creating a multi-layered spectacle of movement and stillness.
The best time to visit depends on your interests. From spring to autumn, the area is perfect for nature observation and outdoor recreation. During specific seasons, organized birdwatching sessions are held, providing a unique opportunity to witness the local ecosystem up close. Whether you are looking for the quietude of a morning birdwatch or the excitement of afternoon water sports, the scenery and available activities change beautifully with the seasons.
There is no shortage of things to do here. You can explore the area via bicycle, enjoy a barbecue around Lake Yanaka, or engage in water sports like canoeing and boating. For those who love the air, sky sports such as hot air ballooning and paragliding are also practiced. Additionally, the area frequently hosts educational events, including plant and bird observation workshops, making it a great place for families and enthusiasts alike.
To support your visit, several hubs are located nearby, including rental cycle stations, barbecue areas around Lake Yanaka, and the 'Michi-no-Eki Kazuwatarase' roadside station. The surrounding region, including the Fujioka area, also features several golf courses, making this a diverse region for various outdoor leisure activities.
