The Stone Reclining Buddha of Tōnosawa is a stone Buddhist statue located along the Tōnosawa mountain route on Mount Kesamaru in Sawairi, Higashi Town, Midori City, Gunma Prefecture. Locally known affectionately as “Neshaka,” meaning “Sleeping Buddha,” the statue was designated a Gunma Prefectural Historic Site in 1993.
Surrounded by abundant nature and a long history of mountain worship, this remote site offers visitors a quiet and deeply atmospheric encounter with Buddhist culture in the mountains.
Mount Kesamaru has long been associated with Shugendō, a Japanese mountain ascetic tradition that combines Buddhist and indigenous spiritual practices. The Tōnosawa area was once a place where ascetics trained in the harsh mountain environment and followed routes through the wilderness as part of their spiritual practice.
The Stone Reclining Buddha is carved directly into a massive rock known as Fudō-iwa. The figure lies with its head facing west, a characteristic feature of the statue.
The carving measures approximately 3.68 meters in length and 1.3 meters in width. Rather than being carved from a separate block of stone, the natural surface of the rock has been skillfully incorporated into the sculpture.
Surrounded by the mountain forest, the reclining figure appears almost as if the mountain itself has taken the form of the Buddha, creating a particularly mysterious and tranquil atmosphere.
The exact date when the Reclining Buddha was created and the identity of its sculptor remain unknown. However, its existence is recorded in “Sawairi Dōnōki,” a work written in 1782 by Takayama Hikokurō, a thinker of the late Edo period. This indicates that the statue was created before that time.
Several theories have been proposed concerning its origins. One local tradition attributes the statue to Kōbō Daishi (Kūkai), while another suggests that it was carved to console the spirits of people who died at the Ashio Copper Mine, which was under the direct control of the Tokugawa shogunate.
Although its precise origins remain uncertain, these traditions reflect the deep spirit of prayer and remembrance associated with the statue.
In front of the Reclining Buddha stands a natural stone known as the Sōrintō, rising approximately 18 meters high. Along with the surrounding Fudō Rock, Fudō Waterfall, Hannya Waterfall, and Sai-no-Kawara, it contributes to the solemn atmosphere of this mountain sanctuary where spirituality and nature come together.
Reaching the Reclining Buddha requires approximately 1.5 hours on foot from the Tōnosawa trailhead along a mountain path.
The nearest railway station is Sawairi Station on the Watarase Keikoku Railway. From the station, visitors travel along a forest road toward the trailhead before continuing on foot.
The route follows a stream through a richly forested mountain environment, offering seasonal scenery along the way.
However, this is a genuine mountain trail rather than an ordinary sightseeing path. Visitors should prepare suitable hiking equipment and allow plenty of time for the journey.
Because wild animals, including bears, may be encountered in mountainous areas, carrying a bear bell or other appropriate wildlife deterrent is recommended. With adequate preparation and attention to safety, reaching the Reclining Buddha deep in the quiet forest can be a memorable experience.
Mount Kesamaru, home to the Reclining Buddha, extends across Nikkō City in Tochigi Prefecture and Numata and Midori cities in Gunma Prefecture. It is counted among Japan’s “Three Hundred Famous Mountains.”
The name Mount Kesamaru collectively refers to several peaks, including Maekesamaru, with an elevation of 1,878 meters, as well as Naka-Kesamaru, Ushiro-Kesamaru, Oku-Kesamaru, and Mount Hōshi. The highest point is Oku-Kesamaru at 1,961 meters.
During the seasons when azaleas and alpine plants are in bloom, many hikers visit the mountain. The ridgelines offer expansive views of the surrounding mountains, while the area’s natural environment is carefully protected within Nikkō National Park.
Roadside Station Tomihiro Museum, located along National Route 122 beside Kusaki Lake, is one of Midori City’s major tourist facilities.
The adjacent Tomihiro Museum features works by Tomihiro Hoshino, a renowned Japanese artist and poet known for his illustrated poetry. The museum provides a quiet setting in which to appreciate his works.
The roadside station also has shops selling local specialties and a restaurant. Its popular yomogi manju, a sweet bun flavored with Japanese mugwort, is one of the local treats available there.
For visitors who find the mountain journey to the original Reclining Buddha difficult, another statue was installed in 1999 on the grounds of Kusaki Drive-In beside Kusaki Lake.
The statue is approximately the same size as the original and provides a more accessible place for visitors to pay their respects.
The drive-in also has a restaurant serving homemade udon noodles and set meals, making it a convenient place to enjoy a meal while taking in the scenery around the lake.
The Stone Reclining Buddha of Tōnosawa is more than a sightseeing attraction. It is a remarkable place where mountain worship, history, Buddhist tradition, and the grandeur of nature come together.
Encountering the reclining Buddha in the stillness of the deep forest creates a powerful sense of tranquility and reverence. The statue’s integration with the natural rock makes it especially distinctive among Buddhist monuments in Japan.
Visitors who combine the hike with sightseeing around Kusaki Lake and the Tomihiro Museum can experience several different aspects of Midori City’s natural and cultural heritage.
For those prepared for a mountain hike, the journey to this secluded Reclining Buddha offers a fascinating glimpse into the spiritual traditions and natural landscapes of rural Japan.
