Kurotakisan Fudoji Temple is a temple of the Obaku school of Zen Buddhism located in Oshiozawa, Nan-moku Village, Kanra District, Gunma Prefecture. Nestled on Mount Kurotakiyama at an elevation of approximately 870 m, the temple stands quietly beneath rocky cliffs where mist from nearby waterfalls fills the air.
For centuries, the temple has been known as the “Inner Sanctuary of Jōshū” and as a sacred site dedicated to Fudō Myōō, the Buddhist deity associated with protection and the overcoming of obstacles. It has attracted devoted worshippers for more than a thousand years.
The origins of Fudoji Temple are said to date back to the Nara period (710–794). According to tradition, the revered Buddhist monk Gyōki visited the area and established a small hermitage where he enshrined a golden Fudō Myōō statue said to have been carved by his own hand.
The statue is still carefully preserved as a hidden Buddhist image and is revealed to the public once every 12 years, in the Year of the Rooster.
The temple fell into decline for a period during the Muromachi period, but was revived in 1675 by the Zen master Chōon Dōkai. It was subsequently established as a temple of the Obaku school of Zen Buddhism.
Chōon is said to have received the patronage of Tokugawa Tsunayoshi, the fifth shogun of the Edo-period Tokugawa shogunate. At the height of its prosperity, the temple is said to have had as many as 200 affiliated temples. Since then, it has continued its long history as a sacred place of worship dedicated to Fudō Myōō.
After passing through the temple gate, visitors are first greeted by the bell tower. The current bell tower was rebuilt in 1981 to replace the former bell, which had been requisitioned during World War II.
The present bell is notable for incorporating the compass of the battleship Musashi as part of its casting, symbolizing a wish for peace. Visitors are permitted to ring the temple bell freely during visiting hours.
Beyond the temple gate stands the Fudō Hall, with a waterfall flowing down behind it. The combination of the cascading water, rugged rocks, and traditional temple buildings creates the solemn atmosphere characteristic of this mountain sanctuary.
Further into the grounds are the Daiyūhōden Hall, which serves as the main hall, the Founder’s Hall, and Kurotakisen Spring. Together, these structures and the surrounding natural landscape create a tranquil and mysterious setting where architecture and nature exist in harmony.
The temple grounds also offer impressive views across the mountains of Nan-moku. On clear days, visitors can look out over the surrounding peaks. Even during summer, cool mountain breezes pass through the grounds, creating a refreshing atmosphere and a sense of the traditional Japanese aesthetic of wabi and sabi.
Mount Kurotakiyama has long been regarded as a sacred mountain associated with mountain worship. According to local tradition, three birds known as the “Three Sacred Birds of Kurotakiyama” inhabit the mountain: the Buddhist paradise flycatcher, the scops owl known locally as mokugyō-dori, and the Japanese bush warbler known as jibishin-chō.
Their calls can sometimes be heard echoing through the quiet mountain temple. The surrounding area is also home to a diverse range of plants and animals, reflecting the rich natural environment that has been preserved around the sanctuary.
Within the temple grounds stands the Great Cedar of Kurotakiyama, which was designated a Natural Monument by Gunma Prefecture on November 11, 1952.
The enormous tree is approximately 41 m tall, with a trunk circumference of about 7.2 m at chest height. It is estimated to be more than 350 years old.
The surrounding mountains are characterized by numerous rocky areas and are not necessarily an ideal environment for large trees. The sight of this cedar having survived and grown for several centuries is therefore particularly impressive.
Having stood alongside Fudoji Temple for generations, the great cedar can be regarded as one of the symbolic landmarks of this sacred mountain sanctuary.
Kurotakisan Fudoji Temple is approximately 25 minutes by car from Shimonita Interchange on the Joshin-Etsu Expressway. As one of the major attractions in Nan-moku Village, the temple welcomes both worshippers and visitors interested in the area’s history and natural scenery.
Each season offers a different experience: fresh greenery in spring, lush forests in summer, colorful autumn foliage, and exceptionally clear mountain air in winter.
Surrounded by centuries of history and magnificent mountain scenery, Kurotakisan Fudoji Temple is more than simply a sightseeing destination. Its tranquil setting offers visitors an opportunity to slow down, reflect, and experience the atmosphere of a traditional Japanese mountain sanctuary.
When visiting Nan-moku Village, consider making the journey to this historic temple and taking time to experience the peaceful atmosphere of Kurotakiyama for yourself.
