Why Mount Kumotori is a Sacred Site for Demon Slayer
Mount Kumotori (くもとりやま) is a mountain with an elevation of 2,017 meters spanning Tokyo, Saitama, and Yamanashi Prefectures, and is known as the highest peak in Tokyo. This mountain has garnered attention from fans of the hugely popular anime and manga “Demon Slayer” as a sacred site, primarily 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 snow-covered mountain village, and the scene where Tanjiro carries Nezuko on his back down the mountain through the snow after she is attacked by a demon remains vividly in many fans’ memories. This setting is believed to be based on the area around Mount Kumotori, and commemorative banners featuring images of Tanjiro and Nezuko have been installed at the trailhead, with the entire community cherishing the connection to Demon Slayer.
The figure 2,017 meters is also impressive, and the mountain drew significant attention as Tokyo’s highest peak in 2017. Then, from 2020 onward, alongside the massive success of Demon Slayer, this mountain became a special place not only for hiking enthusiasts but also for anime fans.
Basic Information and Characteristics of Mount Kumotori
Geographical Features
Mount Kumotori is part of the Oku-Chichibu Mountain Range and is located at the boundary of Okutama Town in Nishi-Tama District, Tokyo, Chichibu City in Saitama Prefecture, and Tanba Village in Kita-Tsuru District, Yamanashi Prefecture. The summit belongs to Tokyo, and as the only mountain in Tokyo that exceeds 2,000 meters, it is also one of Japan’s One Hundred Famous Mountains, beloved by many climbers.
The origin of the mountain’s name has several theories, but it is said to derive from the meaning “a mountain so high it can touch clouds” or from the fact that clouds tend to form near the summit. In fact, standing at the summit, depending on weather conditions, you can enjoy spectacular views of the sea of clouds spreading below, truly seeming as if you could pluck the clouds.
Natural Environment and Highlights
The appeal of Mount Kumotori lies in the fact that, despite being a 2,000-meter-class mountain, it is relatively accessible. The hiking trail is well-maintained, and you can enjoy nature through all four seasons.
From spring through early summer, fresh greenery is beautiful, and flowers such as rhododendrons and azaleas line the hiking trail. Summer attracts many climbers seeking coolness, and autumn paints the entire mountain in fall colors. Winter brings snowfall, requiring experience in winter mountain climbing, but it is also a season where you can experience the snow-covered environment in which Tanjiro and his companions lived in the story.
The views from the summit are also magnificent, and on clear days you can see Mount Fuji, the Southern Japanese Alps, Mount Yatsugatake, and the mountains of Oku-Chichibu at a glance. The view of Mount Fuji in particular is spectacular, and many climbers visit specifically for this scenery.

Points of Interest for Demon Slayer Fans
Banners at the Trailhead
At the Kamozawa trailhead, commemorative banners featuring Tanjiro’s green and black checkered pattern and Nezuko’s pink hemp leaf pattern have been installed. These were placed by the local tourism association and volunteer climbers, creating an atmosphere that enhances the sacred site pilgrimage experience.
Many fans take commemorative photos with these banners before climbing, and on social media, numerous photos are posted with hashtags such as “#Kumotoriyama” and “#DemonSlayerSacredSite”.
Winter Mountain Climbing Evoking the Snow Descent Scene
One of the most impressive scenes in the story is when Tanjiro carries the demon-turned Nezuko on his back down the mountain through snow. Winter on Mount Kumotori features snowfall, allowing visitors to actually experience this scene from the story.
However, winter mountain climbing requires proper snow gear (crampons, ice axes, cold weather clothing, etc.) and experience. Inexperienced beginners attempting this without proper preparation risk getting lost, so be sure to climb with experienced partners or prepare adequately before attempting it.
Summit Panoramic Views and the Story’s Worldview
Standing at the summit of Mount Kumotori, a 360-degree panorama spreads before you. On clear days, Mount Fuji appears distinctly, and the Southern Japanese Alps and Mount Yatsugatake ranges are also visible. Being in the midst of this grand nature allows you to reflect on the deep mountain environment where Tanjiro and his companions lived and the harsh journey they undertook as members of the Demon Slayer Corps.
The summit at dawn is particularly mystical, with the sea of clouds spreading below—truly a spectacular view worthy of the name “Mount Kumotori”.

Mount Kumotori’s Charm Through the Seasons
Spring (April–June)
As snow melts, fresh greenery sprouts, and the mountain fills with vitality. From late April through May, rhododendrons and azaleas color the hiking trail. If residual snow remains, carrying light crampons provides peace of mind.
The temperature is mild during this season, making it one of the best seasons for climbing. However, the Golden Week period is crowded, so early morning departures or weekday climbing is recommended.
Summer (July–August)
The season with the most climbers. Many visit seeking the coolness of a 2,000-meter-class mountain. Near the summit, even in mid-summer, temperatures hover around 20 degrees Celsius, allowing for comfortable hiking.
During summer vacation, many families visit, and mountain huts become busy. However, afternoon thunderstorms become more likely, so prioritize early morning departures and descents.
Autumn (September–November)
The fall foliage season when Mount Kumotori is most beautifully colored. From late September through October, foliage begins at the summit and gradually descends toward lower elevations.
On clear autumn days, the air is crisp and views of Mount Fuji and the Southern Japanese Alps are at their best. However, entering November brings the possibility of early snow, requiring cold-weather preparation.
Winter (December–March)
The snow season requires winter mountain climbing gear and experience. Snow-covered landscapes reminiscent of Tanjiro carrying Nezuko down the mountain spread before you, 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 snow storms create visibility risks. Avoid winter climbing as a beginner, and always climb with experienced partners.
Nearby Tourist Attractions
Lake Okutama
A worthwhile stop before or after climbing Mount Kumotori is Lake Okutama. Selected as one of Japan’s best dam lakes, this beautiful reservoir offers scenic views through all seasons. There are restaurants and souvenir shops along the shoreline, making it ideal for resting after a climb.

The Future of Mount Kumotori and Demon Slayer

The local town of Okutama and tourism associations are seizing this opportunity to undertake various initiatives. From installing banners at trailheads to collaborating with Demon Slayer on events, efforts to enhance its appeal as a sacred site continue.
Conversely, increased climber numbers have raised concerns about environmental impact and behavioral issues. Pack-out all trash, preserve the hiking trail, and show consideration for wildlife—each individual is called upon to act responsibly.
