About Ryumon Gorge | A Hidden Gorge Gem in Koshu City, Yamanashi Prefecture
Overview and Historical Background of Ryumon Gorge
Ryumon Gorge is part of the Hikawa Gorge that spreads from the Tano District to the Tenme District of Yamato Town, Koshu City, Yamanashi Prefecture, and is a scenic area consisting of deep greenery and gorges covering approximately 350 hectares. This area has been designated as “Yamanashi’s Historical and Cultural Park” and the “Ryumon Gorge Landscape Preservation District,” with efforts being made to preserve the natural environment.
The Yamato District of Koshu City is known as the site of the end of the Takeda clan, and has been a historically significant area that flourished along old trade routes. The name “Ryumon Gorge” is said to derive from the fact that the steep terrain of the gorge looks like a gate through which a dragon ascends to heaven.
Geographical Characteristics of Ryumon Gorge
The Hikawa River originates from Mount Kasatori and is a first-class river in the Fuji River water system that flows into the Kofu Basin. Ryumon Gorge is located in the middle reaches of the Hikawa River, and is characterized by gorge terrain formed through erosion by the river over long periods of time. The unique landscape created by granite bedrock being eroded by river flow has captivated visitors throughout the four seasons.
Within the gorge, various waterfalls and pools of different sizes, as well as strange rock formations, are scattered throughout, allowing visitors to enjoy gorge scenery rich in variety. With an appropriate elevation change, the environment is ideal as a hiking course.

Features and Maintenance Status of the Walking Trail
The walking trail at Ryumon Gorge is relatively well-maintained, making it a course that even beginners can walk with confidence. However, since it is a mountain trail along a gorge, please note the following points:

Senga no Iwa (Rock)

Introducing the Highlights of This Course! Famous Spots at Ryumon Gorge
Ochiai Three Waterfalls
Among the spots at Ryumon Gorge, Ochiai Three Waterfalls is particularly popular. True to its name, three waterfalls in succession are the main feature, each displaying a different character—upper, middle, and lower tiers.
The upper waterfall has the greatest drop, with water flowing down the rock surface with force—a spectacular sight. The middle waterfall flows relatively gently, and the lower waterfall forms a wide plunge pool. There is also a viewing point where you can see all three waterfalls at once, making it a popular photography spot.
Particularly during spring snowmelt when water volume increases, and in summer after the rainy season ends, you can see impressive displays. The area around the waterfall is rich in negative ions, and forest bathing effects are expected.
Ryumon Waterfall
Ryumon Waterfall, comparable in popularity to Ochiai Three Waterfalls, is a representative waterfall at Ryumon Gorge. This waterfall is a sliding fall type where water flows down a single sheet of rock, characterized by water gracefully sliding along the rock surface.
The area around Ryumon Waterfall is surrounded by trees, and especially during the new leaf season and autumn foliage periods, the contrast between green or red leaves and white water creates a beautiful landscape. There are also spots where you can get close to the waterfall, allowing you to experience the power of nature while feeling water spray.
Gorge Beauty: Rocks and Pools
In addition to waterfalls, Ryumon Gorge features numerous strange rock formations and deep pools formed over long periods of erosion.
Boulder Groups
Along the walking trail, large rocks carved by river flow are scattered throughout. These rocks display unique shapes and patterns, like works of art created by nature.
Emerald Green Pools
The pools created by the clear Hikawa River shimmer in emerald green or cobalt blue depending on the angle of light. With high transparency, you can sometimes see rocks on the riverbed and fish.
Seiun Temple (Seiun-ji)
Located at the end of the Ryumon Gorge walking trail is Seiun Temple. This temple is an ancient temple of the Rinzai Zen sect, Kenchoji school, and is also known as a temple connected to Takeda Shingen.
Seiun Temple is located at the foot of Mount Tenme, where Takeda Katsuyori met his end, and is historically significant as the site of the end of the Takeda clan. The temple grounds are lined with giant cryptomeria trees several hundred years old, creating a solemn atmosphere.
As a conclusion to hiking in Ryumon Gorge, paying a visit to Seiun Temple and contemplating history is worthwhile. From the temple grounds, you can also view the surrounding mountains, and you can settle your mind in silence.
Four-Season Charms | Seasonal Highlights of Ryumon Gorge
Spring | Season of Azaleas and Fresh Greenery
Spring at Ryumon Gorge is a season of beautiful azalea flowers and fresh greenery. From late April to May, azaleas native to the hiking trail, such as wild azaleas and Japanese azaleas, bloom in vivid pink.
The contrast between azaleas blooming on the gorge rocks and the clear stream is a spring-only landscape. Additionally, during this season, trees begin to sprout, and the bright green of new leaves wraps around the entire gorge. The increase in water from snowmelt also creates impressive waterfalls, allowing you to feel spring’s vitality.
Summer | Deep Green and Refreshing Atmosphere
Summer at Ryumon Gorge is ideal as a deep green retreat from the heat. Within the gorge, temperatures are lower than the surrounding areas, and the sound of the stream and tree shade provide coolness.
During summer, water volume is stable, and you can fully enjoy the beauty of waterfalls and pools. The negative ions brought by water spray and the relaxation effects of forest bathing will refresh both body and mind.
However, summer is also a season with many insects, so insect repellent spray and long sleeves are recommended. Also, remember to hydrate frequently and take heat stroke precautions.
Autumn | Peak Foliage Season
The season when Ryumon Gorge attracts the most tourists is the autumn foliage season. From late October through mid-November, the entire gorge is painted in red and yellow tones, creating breathtakingly beautiful scenery.
Foliage Highlights
- Multiple tree species including Japanese maple, maple, and beech color in a gradient-like landscape
- Fall leaves reflected in the stream create a “water mirror” effect, popular as a photography spot
- Collaboration between Ochiai Three Waterfalls or Ryumon Waterfall and autumn foliage is spectacular
The foliage season sees crowding, particularly on weekends, so visiting on weekdays or during early morning hours is recommended. The combination of light streaming into the gorge in the morning and the foliage creates an especially magical atmosphere.
Winter | Silent Gorge Beauty
Winter at Ryumon Gorge is a season where few people visit, allowing you to monopolize the gorge beauty enveloped in silence. With fallen leaves cleared, the rock faces and stream become more visible, offering a landscape different from spring, summer, and autumn.
On severely cold days, water spray from waterfalls and pools may freeze, creating ice waterfalls and ice pillars. A gorge covered with snow has an ink-wash painting-like beauty with a winter aesthetic.
However, during winter, the walking trail may become dangerous due to frozen roads and snow accumulation. It is important to check the latest information before visiting and come well-equipped.
