Ooidaira Park (おおいだいらこうえん), located in Inabashina Town, Toyotashi City, Aichi Prefecture, is a captivating tourist destination featuring beautiful natural scenery across the four seasons and historical significance. Particularly during autumn’s autumn foliage season, many tourists visit to enjoy the vibrant landscape spreading along the Nagura River. This article provides detailed information you should know before visiting, from the park’s history to highlights, access methods, and surrounding tourist information.
What is Ooidaira Park? History and Origins
History of the Furuhashi Family and Regional Contribution
Ooidaira Park is known as a park associated with the Furuhashi family, sake brewers and village headmen of Inabashina since the mid-Edo period. Particularly Terunori (暉皃), the sixth-generation head of the Furuhashi family, left his name in history as a person who made significant contributions to regional society.
Terunori invested his personal fortune to rescue local residents during the Great Tenpō Famine (1833-1839), an unprecedented disaster. Recognizing the importance of education, he founded a village school (kyōgakkou) to provide learning opportunities for local children, and he also founded agricultural discussion groups to improve agricultural technology. Furthermore, he practiced forestry based on the principle of mutual prosperity and cooperation, working toward the development of the regional economy.
Construction of the Monument to Virtue and Park Development
After Terunori’s death, the district agricultural association erected a monument to virtue (shōtokubi) to honor his achievements. With this monument at its center, the Furuhashi family improved and developed the surrounding area, which became the prototype of the current Ooidaira Park. The park serves as a place to convey regional history while being enjoyed as a place of respite for residents and tourists.
The Four-Season Charm of Ooidaira Park
Spring to Early Summer: Fresh Greenery and Nature’s Vitality
From spring to early summer, Ooidaira Park displays beautiful fresh greenery. Walking along the footpath beside the Nagura River, the vibrant green of newly budding trees and the murmur of clear water soothe the soul. During this period, with relatively few tourists, it can be said to be a hidden gem time when you can fully enjoy quiet nature.
Early Summer Tradition: Firefly Viewing
One of the hidden charms of Ooidaira Park is the firefly display visible in June. The clear water environment of the Nagura River is suitable for the habitation of Genji and Heike fireflies, and from late June to early July each year, a fantastical scene unfolds.
Firefly Viewing Tips:
- Best viewing period: Late June to early July
- Optimal time: Around 7:30 PM to 9:00 PM after sunset
- Viewing location: Around the footpath along the Nagura River
- Notes: Avoid using flashlights and refrain from flash photography
During the firefly viewing season, the local Inabashina Tourism Association occasionally holds firefly viewing events, which are positioned as part of the region’s nature conservation activities.
Autumn Spectacle: A Renowned Autumn Foliage Destination
The time when Ooidaira Park draws the most tourists is autumn’s autumn foliage season. The park is planted with approximately 520 Japanese maples, Acer palmatum, and ginkgo trees. They typically begin coloring in late October, with peak viewing from early to mid-November.
Autumn Foliage Highlights:
- Mirror effect of autumn leaves reflected on the Nagura River water
- Contrast between evergreen trees’ green and the red and yellow of autumn foliage
- Spectacular scenery visible from National Route 257
- Autumn foliage tunnels enjoyed up close while walking along the footpath
During autumn foliage season, the “Momiji (Maple) Festival” is held, featuring autumn flavor bazaars and stalls selling local specialty products and famous foods, drawing large crowds of tourists. During this period, parking cooperation fees may be required, so it is recommended to confirm this in advance.
Winter Serenity: Snow-Covered Scenery and Austere Beauty
In winter, Ooidaira Park offers serene snowy landscapes. The Inabushina area has high elevation and often sees snow accumulation in winter, providing opportunities to encounter fantastical scenery created by snowy vistas and the clear flow of the Nagura River. Because it is a time when tourists are few, it is a season when you can enjoy leisurely walks.
Highlights and Facilities of Ooidaira Park
Monument to Virtue and Historical Structures

Within Ooidaira Park stands a distinctive tree called “Konjo Sawara“. Sawara is a Japanese endemic coniferous tree belonging to the Cupressaceae family.
