This article introduces all the charm that Kiryu River Upstream has to offer.
About Kiryu River Upstream | A Famous Autumn Foliage Spot in Japan’s 100 Best Forests for Forest Bathing
Kiryu River Upstream spans a nature-rich area in the upper reaches of the Kiryu River, which originates from Mount Nemoto at an elevation of approximately 1,199 meters. The Kiryu River is a tributary of the Tone River system that joins the Watarase River and is designated as a first-class river. In its source region flows a beautiful valley known as Nemoto Valley.
Designated as one of Japan’s 100 Best Forests for Forest Bathing in 1986 (Showa 61) and selected as one of the 100 Best Water Source Forests in 1995 (Heisei 7), the area’s rich natural environment is recognized nationwide. Around the southern base of Mount Nemoto, diverse tree species including cedar, cypress, oak, zelkova, and mountain birch grow, displaying the beauty of each season.
Particularly during autumn foliage season, the landscape where trees colored in red and yellow cover both banks of the Kiryu River flowing through pristine nature is spectacular, captivating visitors year after year.
Stunning Autumn Foliage Scenery Created by Colored Trees and Clear Streams
The greatest charm of Kiryu River Upstream is undoubtedly the stunning scenery created by the contrast between the clear stream and autumn foliage. The sight of Japanese maple and zelkova trees colored red and yellow reflecting in the transparent water of the Kiryu River flowing from Mount Nemoto is truly a work of art created by nature.
Walking along the valley, you can enjoy the colorful autumn leaves up close while being enveloped by the pleasant sound of flowing water. The autumn foliage tunnel created by trees jutting out from both banks provides visitors with unforgettable experiences.
On clear days, the contrast between the blue sky, autumn foliage, and clear stream becomes even more vivid, creating perfect conditions for photography. In early morning, mist rises, allowing visitors to enjoy a mystical atmosphere.
Best Time for Autumn Foliage and Color Progression
Autumn foliage at Kiryu River Upstream typically reaches its peak from early November to mid-November. Due to the elevation difference, leaves begin to change color gradually from the upper reaches, allowing visitors to enjoy beautiful autumn foliage for approximately two weeks.

Leaves begin to change color starting from the high-elevation areas of the upper reaches, with the overall area in the early stages of color change. For those wishing to enjoy early foliage, exploring the upper reaches during this period is recommended.

Please note that the best viewing period may vary depending on weather conditions in any given year. We recommend confirming the latest foliage information before your visit.
