What is Kirara no Mori｜The Appeal of Aichi Prefecture’s Largest Beech Primordial Forest
Basic Information About Dantoura Valley Primordial Forest
Dantoura Valley Primordial Forest is a Pacific-type beech primordial forest spanning approximately 130 hectares within the Danto National Forest. The name “Kirara” derives from the dappled sunlight filtering through the forest canopy and the mica (unmo) on the forest floor that sparkles and glimmers in the light. This area is located in the Oku-Mikawa region, which retains particularly dense natural features even within Aichi Prefecture, preserving the primordial appearance of the forest that cannot be experienced in urban areas.
Characteristics of the Primordial Forest and Its Ecosystem
The greatest characteristic of Kirara no Mori is its diverse vegetation. Centered on deciduous broadleaf trees such as beech and water oak, mixed with evergreen conifers like fir and hemlock, it forms a complex forest ecosystem. The sight of giant trees over 200 years old towering toward the sky is awe-inspiring, evoking a sense of the passage of time in visitors.
In the lower layers of the forest, many wetland plants are seen, and from spring through summer, various wild grasses bloom with flowers. Additionally, the rich forest environment becomes a habitat for diverse organisms, with insects, amphibians, mammals, and many other creatures living there.
Why It’s Called “Kirara no Mori”
The reason it is called “Kirara no Mori” locally is that the forest floor contains mica, which sparkles and shimmers when receiving sunlight. Particularly on sunny days when walking through dappled light, the soil and rocks at your feet reflect light, creating a fantastical atmosphere. This natural phenomenon fascinates many visitors as an experience unique to Kirara no Mori.

Four-Season Charm｜Kirara no Mori Annual Calendar
Spring (March to May): Season of Fresh Greenery and Wild Flowers
Spring at Kirara no Mori is a season filled with vital energy as the forest awakens from winter slumber. The fresh green of beech trees is transparent and bright, and walking through dappled light feels refreshing and soul-cleansing.
Various wild flowers bloom on the forest floor. Spring ephemerals like Heloniopsis orientalis, Anemonastrum coronaria, and Paris japonica bloom successively. These plants employ a strategy of photosynthesizing and blooming to produce seeds during a short period before deciduous trees’ leaves grow thick.
Spring is also bird breeding season, with beautiful birdsong echoing throughout the forest. Early morning in the forest is particularly lively with bird choruses, making it an ideal season for bird watching.
Summer (June to August): Deep Green and Seeking Cool Refreshment
Summer at Kirara no Mori is popular as a summer retreat. Located at approximately 900 meters elevation, it is about 5 degrees Celsius cooler than lower elevations, allowing comfortable forest bathing even in midsummer heat.
Inside the forest, trees block sunlight, making it feel even cooler. While humidity is relatively high, the breeze passing through the forest is pleasant, helping visitors forget urban summer heat.
This season brings marsh plants into bloom. Swamp Loiseleuria, Water Chrysanthemum, Spiranthes sinensis subsp. amoena, and other water-loving plants display beautiful flowers. Also, insects are actively active, and various butterflies and dragonflies can be observed.
Summer is a season with many insects, so take thorough insect precautions. Long sleeves, long pants, and insect repellent spray are recommended.
Autumn (September to November): Peak Season for Autumn Foliage Spectacle
Autumn at Kirara no Mori welcomes the most brilliant season of the year. Deciduous broadleaf trees such as beech, water oak, and maple turn gold, red, and orange, creating a magnificent landscape in contrast with the green of evergreen conifers.
Autumn Foliage Peak Times
- Mid-October: Color begins to appear
- Late October to Early November: Peak season
- Mid-November: Leaves begin to fall
Due to higher elevation, autumn foliage begins relatively early within Aichi Prefecture. Particularly on sunny mornings, the angle of light is beautiful and ideal for photography.
Autumn foliage reflected on Danto Lake is another highlight. On calm, windless days, the lake surface acts as a mirror reflecting the forest landscape, creating a fantastical scene. Since fly fishing and lure fishing are also enjoyed at Danto Lake, combining fishing with foliage viewing is popular.
Congestion is expected during autumn foliage season, so visiting on weekdays or early morning is recommended. Since temperatures drop this season, bring warm clothing.
Winter (December to February): Silent Snow-Covered Landscape
Winter at Kirara no Mori transforms into a silent world covered in snow. Snow accumulation varies year to year, but from late December through February, snow often covers the area, allowing snowshoeing and cross-country skiing.
The winter forest becomes more visible with fallen leaves, making it an excellent season for bird watching. Winter birds such as Siberian Rubythroat, Daurian Redstart, and White’s Thrush can be observed, with beautiful photography possible against the white snow and bird colors.
Thorough preparation is necessary for winter visits:
- Install winter tires or chains
- Wear winter clothing, gloves, and hats
- Non-slip shoes (snow boots, etc.)
- Allow time with early sunset
Roads may close during winter, so contacting Shitara Town Tourism Association beforehand to check conditions is recommended.
