Kenmin Koen Ranjo-no-Mori is a massive 115-hectare forest park located in Tonami City, Toyama Prefecture. Surrounded by majestic Tateyama Sugi (Japanese Cedar) and Masan Sugi trees, this park is designed to bring people closer to nature. The park is highly versatile, offering facilities for both educational exploration and outdoor recreation. Visitors can enjoy the Aquatic Plant Garden, the Forest Science Museum, and dedicated BBQ areas, making it a favorite destination for families and nature enthusiasts alike.
The park was developed to preserve the local natural environment while providing a space for the community to connect with nature. Utilizing Toyama's rich natural resources, it serves as an educational hub where visitors can learn about the vital role of forests and plant ecosystems. The Forest Science Museum plays a key role in passing down knowledge about forest conservation and the importance of natural resources to future generations.

There are several must-see spots within Ranjo-no-Mori. First, the "Aquatic Plant Garden & Iris Garden" offers a stunning display of seasonal colors. Next, the "Forest Science Museum" provides an engaging way to deepen your understanding of forest ecology. For those looking to immerse themselves in the scenery, the well-maintained walking trails allow you to stroll through groves of Tateyama Sugi, breathing in the refreshing scent of the woods. These facilities are essential for anyone wishing to combine physical activity with environmental learning.
The beauty of Ranjo-no-Mori changes with the seasons. The most highly recommended time to visit is between May and June, when the Iris Festival takes place, showcasing vibrant, colorful blooms. During the daytime, the park is ideal for educational visits to the museum or a family BBQ. As evening approaches, the changing light through the trees creates a serene and peaceful atmosphere, perfect for a quiet stroll.
Beyond simple walking, the park offers immersive experiences. You can enjoy a BBQ at the dedicated facilities, though please note that you must bring your own food and cooking utensils. Important: The use of charcoal/open flames is strictly prohibited to prevent forest fires. Additionally, you may occasionally encounter guided tours by naturalists (Toyama Nature Guides) who provide professional insights into the local ecosystem. Exploring the botanical gardens and forest bathing (Shinrin-yoku) along the trails are also highly popular activities.
The park is located near several famous Toyama landmarks. The famous Tulip Park in Tonami is a short drive away. The area is easily accessible via Route 359 and is a great stop for those driving through the Hokuriku Expressway toward Toyama City or the center of Tonami.
As this is a natural forest environment, we strongly recommend wearing comfortable walking shoes and clothing suitable for light hiking.
