What is Mt. Fuji's Aokigahara Jukai?
The Aokigahara Jukai is a vast primeval forest spreading to the northwest of Mt. Fuji.
It has a globally rare forest ecosystem formed on lava flows from Mt. Fuji's eruption about 1,200 years ago. When I first visited here, I was overwhelmed by the sight of densely growing trees stretching out like waves. The scenery that spreads out is truly like a vast green ocean, perfectly fitting the name "Jukai" (sea of trees).
This place is not just a tourist spot. It has been the setting for many literary works and art pieces, and is gaining worldwide attention as a representative of Japan's mystical nature. Every time I visit, I make new discoveries and realize the depth of Japan's nature.
It also has very interesting ecological features. The forest formed on the lava terrain is home to hundreds of species of flora and fauna. The calls of birds unique to this area further enhance the forest's mystical atmosphere.
Is Mt. Fuji's Aokigahara Jukai a Dangerous Place?
Based on my 10 years of visiting experience, I'll explain the "dangers" of the Jukai and points for enjoying it safely.
Rumors and Images Surrounding the Jukai
Due to its mystical atmosphere, various dark stories and urban legends have emerged about the Aokigahara Jukai.
However, when you actually visit, you'll find Japan's rich nature and a serene space spreading out. In recent years, well-maintained walking paths and information facilities have been developed, making it a popular spot attracting many tourists from around the world.
I visit the Jukai through all seasons, and every time I make new discoveries. The unique terrain created by lava, rare plants, and scenery changing with the seasons make it a very interesting place from a natural science perspective. Especially early in the morning when mist lingers, the mystical atmosphere intensifies, making it the best time for photography.
Actual Points of Caution
Although it's developed as a nature park, the Aokigahara Jukai is still a primeval forest. From my experience, the following points require special attention:
Due to the undulating lava terrain and densely packed trees, it's easy to lose your sense of direction if you stray from the walking paths. Also, mobile phone signals are often unstable inside the Jukai, and the weather has the characteristic changeability of Mt. Fuji.
Particular caution is needed regarding the unevenness of the ground due to the lava terrain. Even though I've visited many times, I walk carefully, especially in rainy conditions. Also, sudden weather changes typical around Mt. Fuji, especially fog formation, require vigilance. Based on experience, I can't recommend nighttime visits as visibility becomes extremely poor.
Points for Enjoying Safely
I'll share the points I particularly emphasize based on my years of visiting experience.
First, always stick to the maintained walking paths. There are regular guide signs along the paths, allowing you to enjoy sightseeing safely. For first-time visitors, I recommend tours with local guides.
In terms of equipment, ensuring foot safety is particularly important. As the lava terrain can be slippery, I always choose shoes with good grip, like trekking shoes. Also, bringing warm clothing is essential as temperature changes around Mt. Fuji can be significant. I bring a long-sleeved outer garment regardless of the season.
If you happen to get lost, staying in place is the safest option. From my experience, moving around aimlessly can potentially worsen the situation. I recommend always informing someone of your destination before visiting.
Activities to Enjoy in Mt. Fuji's Aokigahara Jukai
I'll introduce the attractive activities unique to the Jukai that I've experienced over 10 years of visits.
Walking the Trails
What I find most appealing is walking the trails. The well-maintained walking paths are safe even for beginners and allow you to fully enjoy the Jukai's nature. Particularly impressive is the silence unique to primeval forests. The experience of walking while listening only to the whispers of trees and bird songs, away from urban noise, refreshes both mind and body.
Each season has its own charm, and I visit every season. Spring's fresh greenery is full of vitality, summer forms a deep green tunnel bringing coolness. In autumn, you can enjoy the color contrast between the black lava and the autumn foliage, and winter shows yet another face with frost-covered trees and snowy landscapes. For photography enthusiasts, there are scattered perfect spots for shooting with Mt. Fuji in the background.
Cave Exploration
The cave network spreading under the Jukai is also one of my favorite spots. Especially the Narusawa Ice Cave is a mysterious space that maintains a temperature around 32°F (0°C) year-round. The mystical terrain created by lava and the beauty of ice pillars formed in winter are must-sees.
The Fugaku Wind Cave is also not to be missed. It has historical value, having been used to preserve silkworm eggs in the past. The tunnel-like cave formed by lava is a valuable spot where you can feel the Earth's workings firsthand.
For both caves, safety equipment like helmets and flashlights are provided on tours, allowing even first-timers to enjoy exploration safely. They're also popular with families with children and are attracting attention as living teaching materials for natural science.

Nature Observation
What I find particularly moving is the Jukai's unique ecosystem. The vitality of plants adapted to the lava terrain never fails to amaze me. The diversity of moss species is especially impressive, and the way they grow clinging to rock surfaces makes me feel the mystery of life.
Encounters with wildlife are also part of the Jukai's charm. If you visit early in the morning, you might see squirrels and wild birds. The chirping of wild birds beautifully echoes through the silent air of the Jukai.
The changing of seasons is also magnificent. In spring, new buds sprout; in summer, a deep green tunnel forms. Autumn foliage creates a beautiful contrast with the blackness of the lava terrain, and in winter, a solemn snowy landscape spreads out. It's also an unparalleled subject for nature photography enthusiasts.
How to Access Mt. Fuji's Aokigahara Jukai from Tokyo
I'll introduce the optimal access methods based on my 10 years of experience.
Using Train and Bus
For train travel, I recommend the route using the JR Chuo Line limited express from Shinjuku Station. It takes about 1 hour to reach Otsuki Station, then change to the Fujikyu Line for about 50 minutes to Kawaguchiko Station. Also, using the limited express "Fuji Kaiyuu" from Shinjuku allows you to go directly to Kawaguchiko. This is convenient for avoiding crowds during tourist seasons.
From Kawaguchiko Station, buses run regularly to Aokigahara Jukai, taking about 30 minutes. When I want to enjoy the early morning forest, I sometimes stay in Kawaguchiko the night before. The transportation cost from Shinjuku to the Jukai is about 3,000 to 4,000 yen one way. I recommend making reservations in advance for limited express trains and sightseeing buses, as they can get crowded, especially on weekends.
Going by Car
When driving from Tokyo, use the Chuo Expressway and exit at Kawaguchiko IC. It's about a 2-hour drive from the city center. From Kawaguchiko IC to Aokigahara Jukai is about a 20-minute drive.
My favorite is the early morning road. The view from the road running along the foothills of Mt. Fuji is exceptional, especially on clear early mornings when you can see Mt. Fuji's figure clearly. There are spacious parking lots at Narusawa Ice Cave and Fugaku Wind Cave, where many tour buses also stop.
Including highway tolls and gas, it costs about 5,000 yen one way. The view of Mt. Fuji from Dangozaka Service Area along the way is also wonderful, making it a recommended rest stop.
Spots to Visit Along with Aokigahara Jukai at Mt. Fuji
After enjoying the charms of the Jukai, please visit these nearby tourist spots as well.
Lake Kawaguchi
Lake Kawaguchi is my go-to spot for Mt. Fuji sightseeing. The reflection of Mt. Fuji on the lake surface is truly a spectacular view. Especially the inverted image of Mt. Fuji in the early morning is perfect for photography. You can enjoy sightseeing boats and rental boats on the lake, and the view of Mt. Fuji from the lake is also impressive.
The surrounding area is full of hot spring facilities and restaurants, perfect for relaxing. I always make sure to rest here after walking through the Jukai. There are many restaurants using local ingredients, so you can enjoy the local cuisine as well.
Mt. Fuji Panoramic Ropeway
The Mt. Fuji Panoramic Ropeway to Mt. Tenjo is a place I often visit after touring the Jukai. The view from the summit is breathtaking, especially on clear days when you can see Mt. Fuji and Lake Kawaguchi at a glance. The "Bell of Tenjo" at the top is also popular as a power spot for love fulfillment, making it recommended for couples sightseeing.
It's conveniently located within walking distance from Kawaguchiko Station. My recommendation is to visit at dusk. The sight of the sun setting behind Mt. Fuji is a beauty that moves my heart no matter how many times I see it.
Oshino Hakkai
Oshino Hakkai is a mystical spot where 8 ponds of Mt. Fuji's spring water are scattered. What particularly moves me is the beauty of the highly transparent water. The clear water through which you can see the bottom of the pond clearly is truly a blessing from Mt. Fuji.
It's also known as a place where traditional Japanese landscapes remain, with old houses and waterwheels scattered around, providing many picturesque spots. It's also popular among photography enthusiasts, and I often visit to capture the changing expressions of the seasons. Early morning is especially popular among photographers, as you can sometimes capture the inverted image of Mt. Fuji reflected on the water surface.
Frequently Asked Questions About Mt. Fuji's Aokigahara Jukai
I'll answer common questions based on my 10 years of visiting experience.
When is the Best Time to Visit the Jukai?
I recommend spring and autumn. Spring is beautiful with fresh greenery, and the temperature is comfortable. May in particular has stable weather and is ideal for walking through the Jukai. Autumn offers a spectacular contrast between the fall colors and the lava terrain, with late October to early November being the best season. However, this period is also crowded with tourists, so I recommend visiting in the morning.
How Long Does Cave Exploration Take?
Narusawa Ice Cave and Fugaku Wind Cave can each be toured in about 30-40 minutes. However, from my experience, if you include time for photography and observing the terrain, it's best to allow about an hour for each cave. The experience becomes even more fulfilling if you listen to the guide's explanations.
Is It Possible to Camp in the Jukai?
Camping inside the Jukai is prohibited. However, there are several wonderful, well-equipped campsites in the surrounding area. I recommend campsites around Lake Shoji or Lake Motosu where you can enjoy views of Mt. Fuji. They require advance reservations, but the facilities are well-developed and comfortable.
Can Children Enjoy It Too?
Yes, the walking paths and cave exploration can be thoroughly enjoyed by children. I sometimes visit with friends' families, and the children are especially fascinated by the cave exploration. However, adult supervision is always necessary, and care must be taken not to stray from the walking paths.
The Aokigahara Jukai is a special place where you can experience the mystery and beauty of nature. Through my 10 years of visits, I have been captivated by its charm many times.
With proper preparation and caution, you can safely have a wonderful experience. Please come and visit this wonderful forest landscape created by Japan's nature.
