A Rich Satoyama Ecosystem
The forest is made up primarily of deciduous broadleaf woodland, including Japanese sawtooth oak and konara oak, together with areas of planted cedar and Japanese cypress.
These forests preserve many characteristics of Japan’s traditional satoyama landscape and provide habitats for a wide variety of wildlife.
The grounds also contain ponds, wetlands, and streams, creating a range of aquatic and waterside environments. The combination of woodland and water habitats supports diverse communities of insects, birds, amphibians, plants, and other organisms.
Because different species appear according to the season and weather conditions, every visit can offer something new to discover.
The Nature Center and Observation Facilities
The central facility is the Nature Center, which features displays about the local environment and a lecture room used for educational programs and presentations.
Visitors can learn about the plants and animals of the forest as well as seasonal changes in the natural environment. The center serves as an important starting point for exploring the surrounding trails.
Rangers and nature interpreters are also stationed at the Nature Center. They provide information about current wildlife sightings, explain features of the forest, and help visitors make the most of their time outdoors.
Regular guided nature walks and hands-on events are held throughout the year, giving visitors the opportunity to observe wildlife while listening to explanations from knowledgeable staff.
Birdwatching Shelters
There are five birdwatching shelters within the forest. These quiet observation points allow visitors to watch birds without disturbing them and provide excellent opportunities to experience the area’s birdlife.
A Network of Well-Maintained Nature Trails
Approximately 3.5 kilometers of observation trails wind through the forest. The trails are divided into routes with names inspired by seasonal plants and scenic features.
Main Walking Trails
Named routes include Sakura-no-michi, Natsutsubaki-no-michi, Nirinsou-no-michi, Utsugi-no-michi, Shida-no-michi, Akamatsu-no-michi, Chigoyuri-no-michi, Miharashi-no-michi, Ajisai-no-michi, Yamabuki-no-michi, and Kaya-no-michi.
The Japanese names refer to plants or landscape features found along the routes, such as cherry blossoms, hydrangeas, azaleas, and scenic viewpoints. Walking these trails provides a simple way to experience the seasonal character of the satoyama.
Special Nature Observation Areas
The forest also has numerous locations designed around particular plants and animals. These include Hanmyo Hiroba, Sawakani-no-sawa, Omurasaki-no-mori, Hotaru-no-sawa, Bataga-hara, Kawasemi-no-ike, Kabutomushi-no-mori, Shijukara-no-mori, and Nosuri-no-oka.
The names reflect creatures or natural features associated with the areas, including tiger beetles, Japanese freshwater crabs, great purple emperor butterflies, fireflies, grasshoppers, kingfishers, rhinoceros beetles, Japanese tits, and buzzards.
The Forest Through the Four Seasons
Spring
Spring brings colorful changes to the forest. Approximately eight varieties of cherry trees and around 15 types of violets bloom in succession, while flowers such as Japanese kerria and Mitsuba azaleas add further color to the landscape.
As temperatures rise, insects become active again. Visitors may see butterflies such as the yellow tip and white-tailed hairstreak, as well as reptiles such as the Japanese grass lizard.
Summer
Summer is an especially exciting season for observing insects attracted to the sap of trees. Japanese rhinoceros beetles and stag beetles are among the popular species that children enjoy searching for in the forest.
Rangers may also provide guidance during nature observation activities, making it easier for visitors to discover insects and understand their behavior.
Autumn
In autumn, the forest becomes rich in nuts and fruits that provide important food for wildlife. Visitors can find acorns, chestnuts, and other seeds and fruits while walking beneath the colorful foliage.
The changing leaves also make autumn an especially enjoyable season for leisurely walks through the forest.
Winter
Winter offers excellent opportunities for birdwatching. With many trees losing their leaves, birds are easier to spot among the branches.
Species that may be observed include Eastern buzzards, Daurian redstarts, red-flanked bluetails, long-tailed tits, Japanese tits, and varied tits.
Many birds can be seen even without binoculars, making winter a particularly accessible season for visitors who are new to birdwatching.
Kakkōso – A Rare Flower Found Only in the Kiryu Area
The area surrounding Kiryu Nature Observation Forest is home to the exceptionally rare Kakkōso, a plant belonging to the primrose family.
Known for its attractive deep pink flowers, Kakkōso has an extremely limited natural distribution. It is found around Mount Narukami in Gunma Prefecture and is regarded as an important symbol of the area’s natural heritage.
The flowers bloom in spring, attracting nature enthusiasts who come to observe this distinctive plant in its natural habitat.
A Satoyama Forest Where People and Nature Coexist
Kiryu Nature Observation Forest is more than simply a park. It is also an important place for protecting and maintaining the satoyama environment and teaching future generations about the value of living alongside nature.
The mountains behind the forest extend toward the Nikko mountain range, helping create the diverse natural environment that supports the area’s ecosystems.
Walking through the forest gives visitors an opportunity to observe the lives of plants and animals at close range while considering the relationship between people and the natural world.
Established as a Center for Environmental Education
Kiryu Nature Observation Forest was developed as a place where people could learn about the importance of nature conservation through direct observation and outdoor experiences.
In 1984, Japan’s then Environment Agency established a nationwide plan to develop facilities dedicated to nature conservation education. The satoyama environment in Kiryu was selected as one of the locations for this initiative.
The site is located in Kawauchi, approximately 6 kilometers northwest of central Kiryu. After a long period of planning and preparation, the facility opened in April 1989.
Rather than replacing the existing landscape with a conventional park, the facility was designed to make effective use of the area’s natural satoyama environment. It continues to provide an important setting for thinking about the relationship between people and nature.

A Forest for Discovering, Learning About, and Protecting Nature
Kiryu Nature Observation Forest offers a chance to experience the rich natural environment of a Japanese satoyama while remaining close to the city.
Every season brings different scenery and wildlife, from spring flowers and summer insects to autumn nuts and winter birds. Visitors can enjoy walking, birdwatching, insect observation, and plant observation according to their own interests.
For travelers interested in Japan’s natural landscapes and traditional relationship between people and forests, the site offers a valuable perspective beyond the country’s famous temples and urban destinations.
By observing the lives of the creatures that inhabit the forest and learning how the satoyama environment is maintained, visitors can gain a deeper appreciation of the importance of protecting nature and passing it on to future generations.
