What Is Nishizawa Gorge (Nishizawa Keikoku)? Clear Streams, Waterfalls, and Granite
Nishizawa Gorge (Nishizawa Keikoku) is a hiking destination in Chichibu-Tama-Kai National Park, in the Mitomi Kawaura area of Yamanashi City. The trail passes a series of waterfalls, including Nanatsugama Godan no Taki (Seven Cauldrons Five-Tier Falls).
Clear streams flowing through primeval forest have carved the granite, shaping a landscape of continuous waterfalls, plunge pools, and smooth rock faces.
The roughly 10 km loop takes at least 3 hours and 30 minutes to complete. Its best-known highlight, Nanatsugama Godan no Taki, is recognized as one of Japan's 100 Best Waterfalls.
A Natural Gorge Trail, Not a Casual Stroll
The trail is maintained, but it is not a paved sightseeing promenade. It follows natural terrain with wet rocks and narrow sections.
Prepare as you would for a light mountain hike rather than an ordinary city walk.
Feeling the Color and Sound of the Water Up Close
As you walk through the trees, you can experience the speed of the current, the sound of the waterfalls, and shifting shades of green reflected on the water.
The water looks different as the weather and light change, even at the same spot. Take time to notice the sound, temperature, and atmosphere as well as the views.
Checking Trail Conditions Before Your Visit Is Essential
Passage conditions on the gorge trail can change due to rockfall, fallen trees, landslides, snow, and other factors.
The trail is closed for the winter from December 1 to April 28 of the following year, and the period may shift depending on snowfall and other conditions.
Before departing, confirm whether the trail is open, check for closures, and review the weather forecast.
Top Things to See at Nishizawa Gorge: Nanatsugama Godan Falls and Other Waterfalls
The appeal lies not in a single waterfall but in how the water, rock formations, and forest scenery change along the trail.
Prioritize safe footing and stop only at places where you can stand without blocking the trail.
Nanatsugama Godan Falls (Nanatsugama Godan no Taki)
Nanatsugama Godan Falls is Nishizawa Gorge's signature sight, with water cascading through five tiers and a series of plunge pools.
The waterfall drops about 30 meters across five tiers and is recognized as one of Japan's 100 Best Waterfalls.
Located about a 2-hour walk from the gorge entrance, the falls are surrounded by rock, trees, and vividly colored water. The scenery is especially striking during the fresh greenery of early summer and the autumn foliage season.
Mie no Taki (Threefold Falls)
Mie no Taki is notable for its stepped flow and the color of the water framed by rock.
Its appearance changes with water volume and light conditions. Do not approach the edge; view it from a safe position.
Ryūjin no Taki, Koiito no Taki, and Teisen no Taki
The gorge contains waterfalls of different shapes and character, including Ryūjin no Taki (Dragon God Falls), Koiito no Taki (Love Thread Falls), and Teisen no Taki.
Look beyond their size and notice how the water traces the rock, how moss frames each cascade, and how sunlight filters through the trees.
The Futamata Suspension Bridge and the Depth of the Forest
From the Futamata Suspension Bridge, you can take in both the mountain stream and the forest surrounding the valley.
On the bridge, do not linger too long; yield to those coming from the opposite direction, and cross while being mindful of the swaying and your footing.
Best Time to Visit Nishizawa Gorge: Seasonal Highlights
Nishizawa Gorge changes from spring through autumn, and each season brings different scenery and hiking conditions.
Peak conditions vary with the weather, so check current flower reports and autumn foliage updates before visiting.
The following table summarizes seasonal highlights and preparation priorities.
| Season | Landscape Feature | Preparation Priority |
|---|---|---|
| Spring | Budding and flowers | Extra layers for cool mornings and evenings |
| Early summer | Fresh green and clear streams | Rain gear |
| Summer | Deep green and the sound of water | Heat precautions |
| Autumn | Autumn leaves and rock faces | Crowd planning |
Spring Highlights (Early to Mid-May): New Growth and Rhododendrons
In spring, trees begin to bud and soft greens spread across the slopes of the gorge.
Rhododendrons are generally at their best from early to mid-May. Check both current bloom reports and whether the trail is open.
In Early Summer, Fresh Greenery Highlights the Water
As young leaves fill the forest, the green surroundings create a vivid contrast with the white water.
After rain, stones and wooden paths become slippery, so keep your attention on your footing even when the scenery is striking.
Autumn Highlights (Mid-October to Early November): Foliage and Waterfalls
In autumn, beech, maple, and Mongolian oak color the gorge. Foliage is generally at its best from mid-October to early November, when layered colors surround the waterfalls and plunge pools.
During the busy autumn season, avoid occupying photo spots for long periods and let faster hikers pass on narrow sections.
Clothing and Items to Bring for Hiking Nishizawa Gorge
Safe hiking requires equipment suited to wet surfaces, temperature changes, and sudden shifts in weather.
Prioritize comfort, traction, and protection over appearance.
Organizing your gear by purpose can help you avoid forgetting essential items.
| Purpose | Items to Prepare | Reason |
|---|---|---|
| Footing | Non-slip shoes | To handle wet rocks |
| Head | Helmet | Protection against rockfall |
| Weather | Rain gear and warm clothing | To handle changes |
| Activity | Drinks and trail snacks | Refueling along the way |
| Navigation | Map and communication device | To follow the route and receive updates |
Choose Shoes with Reliable Traction
Flat-soled city-walking shoes and shoes that become slippery when wet are not suited to the gorge trail.
Choose hiking shoes that support the ankles and have deeply treaded, slip-resistant soles.
Protect Your Head with a Helmet
To prepare for hazards such as rockfall and fallen trees, wear a helmet.
When wearing it, adjust the chin strap so it does not shift while you walk.
Use Luggage That Keeps Both Hands Free
You may need to use handrails or chains on narrow sections and steps, so carry a backpack that keeps both hands free.
Secure your camera and smartphone with a strap or store them safely to prevent drops.
Manage Your Food and Trash
Bring enough drinks and trail snacks for your needs, and carry out all packaging and leftovers.
Because the loop takes at least 3 hours and 30 minutes, carry extra water and trail snacks.
To avoid attracting wildlife, do not leave or discard food along the path.
