Kombugluro Pond Natural Museum Park is situated adjacent to the urban area in the northern part of Kashiwa City, Chiba Prefecture, while preserving a rich natural environment. This park, which features vast forests and groundwater ponds equivalent to approximately four Tokyo Domes in size (18.5 hectares), plays an important role as a natural water source for Tega Swamp while being cherished as a place of relaxation for citizens. This article provides a detailed introduction to the charm, highlights, access methods, and ways to enjoy this precious natural park.
About Kombugluro Pond Natural Museum Park
Kombugluro Pond Natural Museum Park is a nature preserve located in Nakajuuyoji, Kashiwa City, Chiba Prefecture. Centered around two main groundwater ponds called “Kombugluro Pond” and “Benten Pond,” which give the park its name, abundant forests spread throughout the area.
History and Origin of the Park
In the 1980s, as urban development progressed in the northern part of Kashiwa City, concerns about environmental deterioration in the surrounding area grew. To protect this precious natural environment, conservation activities for “Kombugluro Pond” and the surrounding forest initiated by citizens began. Through the dedication of citizens and cooperation with the municipal government, the area was developed into the current natural museum park, and sustainable satoyama conservation activities are being implemented as the “100-Year Forest Project Nurtured by Citizens.”
Importance as a Water Source for Tega Swamp
Kombugluro Pond and Benten Pond are among the existing natural water sources of the Oobori River, which flows into Tega Swamp. While there are many springs within Kashiwa City, these two ponds are particularly abundant in water volume and maintain stable groundwater flow throughout the year. The unique ecosystem formed by groundwater plays an important role in environmental conservation in the surrounding area.
Natural Environment and Ecosystem of the Park
Cool Temperate Plant Environment Created by Groundwater
The forest around Kombugluro Pond is maintained at a lower temperature than the surrounding environment due to the influence of groundwater. This special environment allows cool temperate plants, which are normally distributed in northern regions, to grow, making it possible to observe vegetation that is extremely rare even within Chiba Prefecture. This phenomenon is called “reverse distribution” and has become an academically valuable natural environment.
Plants Through the Four Seasons
Spring brings beautiful blooming mountain cherries, dyeing the entire forest in pale pink. During the new greenery season, various trees come into leaf, and you can enjoy scenery full of vitality.
Summer creates a cool atmosphere as the deep green forest emerges, and combined with the coldness of the groundwater, becomes a summer retreat away from the urban heat.
Autumn brings color to broad-leaved trees including Japanese maple, offering spectacular autumn foliage. The forest painted in red and yellow captivates all who visit it—a spectacular sight.
Winter sees deciduous trees drop their leaves, making the forest structure clearly visible. The season is also suitable for observing winter birds.
Abundant Wildlife
With good fortune, you can encounter various wild animals in the park.
Mammals: Raccoon dogs and wild rabbits inhabit the area and can be encountered during early morning and evening hours.
Birds: You may glimpse the beautiful kingfisher, making it a popular spot for birdwatching enthusiasts. Various other wild birds can be observed throughout the seasons.
Insects: Summer offers sightings of insects popular with children such as Japanese beetles and stag beetles. Dragonfly species are abundant, and a dedicated “Dragonfly Pond” has been established.
Aquatic Organisms: Freshwater fish including Japanese killifish and various aquatic insects inhabit the waters.
Conservation Activities for Rare Species
Rare species conservation and regeneration projects are being implemented in cooperation with nearby universities, carrying out protection activities for endangered animals and plants. Monitoring surveys are conducted regularly to continually observe changes in the ecosystem.
Facilities and Highlights in the Park
Four Ponds
The park contains four ponds, each with its own characteristics.
Kombugluro Pond: The main groundwater pond and symbol of the park. Boasting abundant water volume, wetland-specific plants grow around its perimeter.
Benten Pond: Another main groundwater pond alongside Kombugluro Pond. The scenery where the forest is reflected in its quiet waters is exceptional.
Fuji Pond: As its name suggests, a pond where wisteria flowers are beautiful.
Dragonfly Pond: A pond developed as a habitat for dragonflies, where diverse dragonfly species can be observed.
Walking Paths and Walking Courses
The park features maintained walking paths, and the course circling all the ponds takes approximately one and a half hours and is ideal for walking. Course design takes advantage of the undulating terrain, providing moderate exercise. While the paths are relatively well-maintained, some natural areas remain, so walking shoes are recommended.
Observation Decks and Rest Spots
Observation decks are installed around the ponds, ideal for observing wild birds and aquatic organisms. Benches are also positioned throughout, allowing for leisurely rest in the natural surroundings.
Citizen-Participation-Type Conservation Activities
Volunteer Activities
A distinctive feature of Kombugluro Pond Natural Museum Park is that conservation activities are centered on citizen volunteers. As part of satoyama conservation, grass cutting, thinning, and removal of invasive species are conducted regularly.
Environmental Education Programs
Numerous elementary schools within the city use the park as an outdoor learning destination, where children interact with nature and learn the importance of environmental stewardship. Nature observation sessions and lectures by specialists are held regularly.
100-Year Forest Project
As the “100-Year Forest Project Nurtured by Citizens,” efforts are underway to nurture the forest from a long-term perspective. This project has been recognized by the Japan UNESCO Association and is drawing attention as a model case for sustainable nature conservation.
