About Aichi Prefectural Forest
History and Overview
Aichi Prefectural Forest is a forest recreation facility opened by Aichi Prefecture in July 1970 (Showa 45) to commemorate the 100th anniversary of the Meiji era. Developed within the Hōrainji Prefectural Forest, this facility initially opened as a “Visitor Lodge” accommodation facility, and has subsequently been expanded with various facilities in stages.
Spreading at the foot of Hōrainji Mountain in the Tōtōkawa region in eastern Aichi Prefecture in Shinshiro City, this forest is located in the headwater region of the Uren River, which is the water source of the Toyokawa Canal. It has received high evaluations from the Ministry of the Environment and the Forestry Agency due to its abundant water sources and beautiful forest landscapes.
The Value of Being Selected for “Forest Bathing Forests 100 Selections” and “Water Source Forests 100 Selections”
The reason Aichi Prefectural Forest is recognized nationally lies in its outstanding natural environment.
“Forest Bathing Forests 100 Selections” was selected in 1986 by the Forestry Agency and the Green Civilization Society, choosing excellent forests suitable for forest bathing from across the nation. Aichi Prefectural Forest was evaluated for its abundant tree species, clear air, and well-maintained hiking trails.
“Water Source Forests 100 Selections” was selected in 1995 by the Forestry Agency, designating forests with high water source preservation functions. The Hōrainji Prefectural Forest, as the headwater region of the Uren River, bears important water sources for the Tōtōkawa region, and the balance between its conservation and utilization has been highly evaluated.
The number of forests selected for both “100 Selections” is limited nationwide, and Aichi Prefectural Forest stands as a rare presence, achieving the coexistence of nature conservation and forest recreation.
The Rich Nature of Hōrainji Prefectural Forest
The Hōrainji Prefectural Forest, with its expansive 572-hectare area, is a treasure trove of diverse flora and fauna. The undulating terrain creates various vegetation zones, and it is particularly known as a natural habitat for Hosoba Shakunage.
The forest is a mix of artificial forests of cedar and cypress, and broadleaf forests of Japanese oak and water oak, displaying different appearances through the four seasons. Spring’s fresh greenery, summer’s deep green, autumn’s fall foliage, and winter’s silence each offer reasons to visit.
A wide variety of bird species are present, and the bird observation pavilion allows observation of various birds throughout the year. Additionally, clear streams are home to stream fish, making the area popular as a spot for river play.
