【Demon Slayer】Kumotori Mountain (Tokyo) Complete Guide | Thorough Explanation of Tanjiro and Nezuko’s Sacred Site
Why Kumotori Mountain is a Sacred Site for Demon Slayer
Kumotori Mountain (くもとりやま) is a 2,017-meter-high peak that straddles Tokyo, Saitama, and Yamanashi prefectures, and is known as the highest peak in Tokyo. This mountain has garnered attention as a sacred site among fans of the wildly popular anime and manga “Demon Slayer” because it is believed to be the model for the hometown of the protagonist Tanjiro Kamado (竈門炭治郎) and his sister Nezuko Kamado (竈門禰豆子).
In the story, Tanjiro and Nezuko live in a snowy mountain village, and the scene where Tanjiro carries the demon-attacked Nezuko on his back and descends the mountain through the snow has left a lasting impression on many fans. The area around Kumotori Mountain is thought to be the setting for this scene, and banners featuring Tanjiro and Nezuko have been installed at the trailhead, with the entire region cherishing its connection to Demon Slayer.
The figure of 2,017 meters is also striking, and in 2017 the mountain garnered significant attention as Tokyo’s highest peak. After 2020, with the massive success of Demon Slayer, this mountain became a special place not only for mountain climbing enthusiasts but also for anime fans.
Basic Information and Characteristics of Kumotori Mountain
Geographical Features
Kumotori Mountain is part of the Oku-Chichibu Mountains and is located at the boundary between Okutama Town in Nishi-Tama County, Tokyo; Chichibu City, Saitama; and Tanabe Village in Kitatsuru County, Yamanashi. The summit belongs to Tokyo and is known as the only mountain in Tokyo exceeding 2,000 meters, as well as one of Japan’s One Hundred Famous Mountains, beloved by many climbers.
The origin of the mountain’s name has various theories, but it is said to be named for meaning “a mountain so high it can take the clouds” or because clouds tend to form near the summit. Standing on the actual summit, depending on weather conditions, a sea of clouds can spread beneath your feet, revealing a truly spectacular view that seems to allow you to take the clouds.
Natural Environment and Attractions
The charm of Kumotori Mountain lies in its relatively easy accessibility despite being a 2,000-meter-class peak. The hiking trail is well-maintained, and you can enjoy nature in all four seasons.
From spring through early summer, the fresh green foliage is beautiful, with flowers like rhododendrons and azaleas adorning the hiking trail. Summer attracts climbers seeking cool temperatures, and autumn sees the entire mountain dyed in fall colors. Winter brings snow, requiring experience in winter mountain climbing, but it is also a season where you can experience the snowy environment where Tanjiro and the others lived in the story.
The views from the summit are also magnificent, and on clear days you can see Mount Fuji, the Southern Alps, the Yatsugatake Mountains, and the peaks of the Oku-Chichibu range all at once. The view of Mount Fuji is particularly spectacular, drawing many climbers to visit for this sight alone.
Major Hiking Routes and Access Methods
There are multiple hiking routes to Kumotori Mountain, but I will introduce the representative routes here.
Kamozawa Route (Most Popular)
The route from the Kamozawa trailhead is the most used course for Kumotori Mountain climbing. This route is characterized by relatively gentle climbing throughout and is suitable for a wide range of people from beginners to intermediate climbers.
Access Method
- From JR Ome Line Okutama Station, take the Nishi-Tokyo Bus “Kamozawa Nishi” bound bus for approximately 35 minutes to “Kamozawa” bus stop
- For vehicles, the Kosode Parking Area (free, approximately 20 spaces) is available
Course Time
- Up: approximately 5–6 hours
- Down: approximately 4–5 hours
- Day hike possible, but early morning departure is essential
At the Kamozawa trailhead, banners featuring characters from Demon Slayer have been installed, enhancing the sacred site pilgrimage atmosphere. Seeing banners with Tanjiro’s checkered pattern and Nezuko’s hemp leaf pattern builds anticipation for the mountain you’re about to climb.
Mitsunine Shrine Route (from Saitama Side)
There is also a route that approaches from Mitsunine Shrine in Chichibu City, Saitama. This route is longer and requires more stamina, but allows for enjoyable ridge walking past peaks like Kirimogi Peak and Shiraiwayama.
Access Method
- From Seibu Chichibu Station, take the Seibu Kanko Bus “Mitsunine Shrine” bound bus for approximately 75 minutes
- Mitsunine Shrine has a parking area (paid)
Course Time
- Up: approximately 6–7 hours
- Down: approximately 5–6 hours
- Mountain lodge stay is recommended
This route is popular among climbers who want to enjoy a quieter mountain experience and closely connect with nature, as it is quieter than the Kamozawa route.
Nippara Route (Separate Route on Okutama Side)
The route from Nippara (日原) is a course that reaches Kumotori Mountain via Nanatsu-Ishi Mountain. Due to its longer distance and greater elevation gain, this is a route for experienced hikers.
Course Time
- Up: approximately 6–7 hours
- Down: approximately 5–6 hours
Day Hike vs. Mountain Lodge Stay
Day Hiking in Practice
Day hiking of Kumotori Mountain is possible, but the round trip takes approximately 9–11 hours, requiring adequate stamina and early morning departure. Especially when using the Kamozawa route, a typical schedule looks like the following:
Standard Schedule for Day Hiking
- 5:00–6:00: Depart from Kamozawa trailhead
- 11:00–12:00: Arrive at Kumotori Mountain summit
- 12:30–13:00: Depart from summit
- 17:00–18:00: Return to Kamozawa trailhead
When planning a day hike, it is important to consider daylight hours, and particularly in fall and winter when sunset comes early, caution is necessary. Also, equipment to handle sudden weather changes is essential.
Enjoying Leisurely with a Mountain Lodge Stay
There are multiple mountain lodges on Kumotori Mountain, allowing you to enjoy the mountain at a relaxed pace over a two-day, one-night itinerary.
Main Mountain Lodges
- Kumotori Sanso
- Mountain lodge located directly below the summit
- Capacity: approximately 200 people
- Operating period: Year-round (verify in advance)
- Dinner and breakfast plans available
- Kumotori Emergency Shelter
- Unmanned emergency shelter
- Primarily for emergency use
- Nanatsu-Ishi Lodge
- Lodge near Nanatsu-Ishi Mountain
- Convenient when using the Nippara route
The advantages of staying at a mountain lodge include being able to leisurely enjoy the sunrise from the summit in the early morning and the spectacular view during sunset. The setting sun over Mount Fuji and a starry night sky are luxurious experiences unattainable with a day hike.
Points of Interest for Demon Slayer Fans
Banners at the Trailhead
At the Kamozawa trailhead, banners featuring Tanjiro’s green and black checkered pattern and Nezuko’s pink hemp leaf pattern have been installed. These were set up by the local tourism association and volunteer climbers, enhancing the sacred site pilgrimage atmosphere.
Many fans take commemorative photos with these banners before climbing, and numerous photos are posted on social media with hashtags such as “#kumotoriyama” and “#demonslayersacredsite.”
Winter Climbing Evoking the Descent Through Snow
One of the most memorable scenes in the story is when Tanjiro carries the demon-turned Nezuko on his back and descends through the snow. Winter on Kumotori Mountain features snowfall, providing an environment where you can actually experience this scene.
However, winter climbing requires snow mountain equipment (crampons, ice axes, winter clothing, etc.) and experience. If beginners attempt it recklessly, there is a risk of getting lost. Always climb with experienced mountaineers or prepare sufficiently before attempting it.
Spectacular View from the Summit and the Story’s World
Standing on the Kumotori Mountain summit reveals a 360-degree panorama. On clear days, Mount Fuji appears distinctly visible, and the Southern Alps and Yatsugatake mountain range can also be seen. Standing amid this magnificent nature allows you to reflect on the deep mountainous environment where Tanjiro and the others lived and the arduous journey they took as members of the Demon Slayer Corps.
The summit is particularly mystical in the early morning, with the spectacle of clouds spreading below in a sea of clouds, a sight truly worthy of the mountain’s name “Kumotori.”
Preparation and Precautions for Climbing

The Charm of Kumotori Mountain Through the Four Seasons
Spring (April–June)
As snow melts, fresh green foliage sprouts, and the mountain fills with life force. From late April to May, rhododendrons and azaleas color the hiking trail. If snow remains, carrying light crampons is reassuring.
The temperature is mild during this season, making it one of the best times for climbing. However, the Golden Week period is crowded, so early morning departures or weekday climbing is recommended.
Summer (July–August)
The busiest season for climbers. Many come seeking the coolness of a 2,000-meter-class peak. Near the summit, even in midsummer, temperatures hover around 20 degrees Celsius, allowing for comfortable climbing.
During summer vacation, many families visit, and mountain lodges are busy. However, the afternoon brings increased risk of thunderstorms, so early starts and early descents should be practiced.
Autumn (September–November)
The fall foliage season when Kumotori Mountain is most beautifully colored. From late September to October, fall colors begin at the summit and gradually descend toward lower elevations.
On clear autumn days, the air is crisp, and views of Mount Fuji and the Southern Alps are excellent. However, early snow is possible from November onward, requiring winter precautions.
Winter (December–March)
Snow accumulation requires snow mountain equipment and experience. Snow-covered landscapes reminiscent of Tanjiro descending with Nezuko on his back unfold, making this season particularly meaningful for Demon Slayer fans.
Winter sees fewer climbers, allowing for quiet mountain experiences, but temperatures often drop below freezing, and wind and snow create visibility risks. Beginners should avoid winter climbing and always climb with experienced mountaineers.
Nearby Tourist Attractions
Lake Okutama
Before or after climbing Kumotori Mountain, be sure to visit Lake Okutama. This beautiful reservoir lake, selected as one of Japan’s best dam lakes, offers scenic beauty in all seasons. There are restaurants and souvenir shops along the lakeshore, making it perfect for rest after climbing.
Hatonokuchi Gorge
Close to Okutama Station, Hatonokuchi Gorge features beautiful clear streams and rock formations. With well-maintained walking paths, light hiking is possible. Many visit to warm up before climbing or refresh themselves after descent.
Okutama Hot Spring
To recover from climbing fatigue, Okutama Hot Spring is recommended. The day-bath facility “Moegi no Yu” allows you to soak in alkaline hot spring waters while viewing the Okutama landscape.
The Future of Demon Slayer and Kumotori Mountain
Following Demon Slayer’s massive success, Kumotori Mountain has gained new appeal. In addition to traditional mountain climbing enthusiasts, a new demographic of anime fans now visits the mountain, contributing to regional revitalization.
The local Okutama Town and tourism association are taking advantage of this opportunity with various initiatives. These include banner installations at trailheads and events collaborating with Demon Slayer, efforts to enhance its appeal as a sacred site.
Conversely, problems have arisen with increased climber numbers, including environmental burden and etiquette issues. Garbage removal, trail conservation, and consideration for wildlife are concerns requiring responsible individual behavior.
Conclusion: Experience the World of Tanjiro and Nezuko on Kumotori Mountain
Kumotori Mountain is Tokyo’s highest peak and one of Japan’s One Hundred Famous Mountains, making it a special mountain for climbers. And it has gained new significance as a Demon Slayer sacred site.
Standing on the 2,017-meter summit and gazing at the 360-degree panorama, you can truly experience the deep mountainous environment where Tanjiro and Nezuko lived. Reflecting on the descent through snow and the arduous journey as Demon Slayer Corps members deepens understanding of the work.
Climbing requires thorough preparation and stamina, but the sense of accomplishment and spectacular views gained at the summit are incomparable. Kumotori Mountain can be enjoyed at your own pace, whether day hiking or staying at a lodge.
Why not experience something special on this wonderful mountain, whether you are a Demon Slayer fan or a mountain climbing enthusiast? However, prioritize safety, maintain respect for nature, and practice responsible climbing.
Just as Tanjiro became stronger to protect his family, we bear responsibility for protecting nature and preserving beautiful mountains for future generations. May climbing Kumotori Mountain become an unforgettable memory for everyone.
