Mizukami Funayama Shrine is a historic Shinto shrine in Tokura, Chikuma City, Nagano Prefecture. Standing near the Chikuma River, the shrine has long been closely connected with the history of the surrounding community.
The area once flourished as Shimotokura-juku, a post town along the Hokkoku Kaido, an important highway that connected the inland regions of central Japan with the Sea of Japan. Travelers heading toward Zenkoji Temple passed through the town, and the shrine served as an important place of worship for local residents and travelers alike.
Today, Mizukami Funayama Shrine is particularly notable for its Nationally Designated Important Cultural Property main sanctuary, whose elaborate wood carvings represent some of the finest surviving examples of traditional shrine decoration in the region.
The exact date of the shrine’s foundation is unknown. According to tradition, however, the shrine was established as a branch shrine of Suwa Taisha in 1603, during the early Edo period, around the time that Shimotokura-juku was established as a post town following the development of the Hokkoku Kaido.
The principal deity enshrined here is Takeminakata-no-Kami, the deity worshipped at Suwa Taisha. Takeminakata-no-Kami has traditionally been revered as a deity of martial strength, agriculture and water, making him particularly significant to communities living along the Chikuma River.
The shrine was originally known as Suwa Shrine. Its location beside the Chikuma River, however, meant that flooding repeatedly threatened the buildings. Whenever the river overflowed, local residents rebuilt and repaired the shrine, preserving their religious traditions through generations of hardship.
The present main sanctuary was built through a remarkable community effort. Construction began in 1785, when the people of Shimotokura-juku joined forces to rebuild the shrine. After approximately five years of work, the sanctuary was completed in 1789.
The design and construction were carried out by Shibamiya Chozaemon Kaneshige, a master carpenter of the Osumi school of Suwa shrine carpentry. The building is regarded as one of his representative works and demonstrates the extraordinary technical ability of craftsmen active during the Edo period.
The main sanctuary is built in the Ichiken-sha Nagare-zukuri style, a traditional shrine architectural form characterized by a gracefully extended and gently curved front roof.
With its elegant proportions and sweeping roofline, the sanctuary is said to be the largest example of this architectural form in Nagano Prefecture. The combination of structural balance and elaborate decoration gives the building an especially impressive appearance.
The sanctuary was first registered as a Tokura Town Tangible Cultural Property in 1965. In 1988, its historical and artistic importance was formally recognized when it was designated a National Important Cultural Property of Japan.
The greatest attraction of Mizukami Funayama Shrine is the extraordinary collection of carvings surrounding the main sanctuary.
Created by Shibamiya Chozaemon Kaneshige, these carvings represent the height of decorative craftsmanship of the period. Plants, animals and mythical creatures are rendered with remarkable depth and movement, transforming the architectural surfaces into a rich visual narrative.
The carving known as “Rabbit among Cycads” combines delicately rendered foliage with the charming figure of a rabbit. The contrast between the intricate plant forms and the lively animal creates a graceful and expressive composition.
“Turtle among Waves” depicts a turtle moving calmly through powerful waves. The dramatic movement of the water contrasts with the steady strength of the turtle, demonstrating the sculptor’s ability to create a sense of motion in wood.
The ascending and descending dragons are among the most striking carvings at the shrine. One dragon appears to rise toward the heavens while the other descends toward the earth, creating a dramatic visual contrast.
These carvings are more than decorative details. Each figure is carefully modeled in three dimensions, and the stories and symbolism embedded in the imagery provide a glimpse into the artistic world and religious imagination of Edo-period Japan.
Although the shrine was originally worshipped as Suwa Shrine, it received official authorization for its shrine name from the Yoshida family of Kyoto in 1835. It was then renamed Mizukami Funayama Shrine.
The Yoshida family played an important role in the organization and recognition of Shinto shrines during the Edo period. The official authorization of the new name marked an important stage in the shrine’s history and reinforced its position as the principal guardian shrine of the local community.
Another remarkable historical object on the shrine grounds is a large stone lantern known as the “Offering Lantern of the Meshi-mori Women.”
It was dedicated in July 1839 by 52 women who worked at the post town of Shimotokura, together with the owners of the inns where they worked. The stone lantern stands approximately 159 centimeters high and reaches about 75 centimeters at its widest point.
The names of all 52 women are engraved on the pedestal. This makes the lantern an unusually personal historical record of life in an Edo-period post town.
Shimotokura-juku prospered from the constant movement of travelers, including pilgrims traveling to Zenkoji. The women who worked there would have encountered travelers from many parts of Japan. The lantern is thought to reflect their hopes and prayers for happiness, security and a better life.
The stone lantern has been designated a Chikuma City Tangible Cultural Property and is valued not only as a religious object but also as an important historical record of life in a former post town.
Because of its connection with Suwa worship, Mizukami Funayama Shrine also holds an Onbashira Festival, following the tradition of Suwa Taisha.
The festival is held once every seven years according to the traditional Japanese counting system, in April of the Year of the Monkey and the Year of the Tiger. The event brings the local community together for a spectacular procession in which large sacred pillars are transported through the town.
The powerful sight of the Onbashira being pulled by local residents represents both community solidarity and the transmission of traditional culture from one generation to the next. In 2000, the festival was designated an Intangible Folk Cultural Property of Chikuma City.
A large kunugi oak still stands within the shrine grounds as a remnant of the woodland that once grew here.
A record from 1924 states that the grounds once contained ten large kunugi trees measuring at least 1.82 meters in circumference at chest height. The largest reportedly measured approximately 2.25 meters.
Kunugi oaks have traditionally been important to rural Japanese life. Their wood was used for firewood and charcoal, while the trees were also valued for their acorns. The old tree at the shrine is said to have served as a parent tree from which acorns were collected and used to plant new trees in the surrounding mountains.
The tree therefore represents more than a natural feature. It is a reminder of the close relationship between the shrine, the surrounding forests and the everyday life of the local community.
The history of Mizukami Funayama Shrine cannot be separated from the Chikuma River. The river brought prosperity to the settlements along its banks, but it also repeatedly caused destructive floods.
The shrine’s repeated reconstruction demonstrates the determination of local people to preserve their place of worship despite these natural disasters. Its present sanctuary, completed in 1789, is the result of that long tradition of community support.
The connection with the Hokkoku Kaido adds another dimension to the shrine’s history. During the Edo period, travelers, merchants and pilgrims passed through Shimotokura-juku, making the surrounding area a meeting point between local communities and people traveling across Japan.
Mizukami Funayama Shrine brings together several distinctive elements of the history of Chikuma: the Chikuma River, the Hokkoku Kaido, Suwa religious traditions, Edo-period craftsmanship and the culture of a historic post town.
The National Important Cultural Property main sanctuary is the highlight, particularly for visitors interested in traditional Japanese architecture and woodcarving. The stone lantern bearing the names of 52 women provides a more intimate glimpse into the lives of people who lived and worked in the post town nearly two centuries ago.
The Onbashira Festival, meanwhile, shows that the shrine is not simply a monument to the past. Its traditions continue to be supported by the local community today.
Mizukami Funayama Shrine is located in Tokura, Chikuma City, Nagano Prefecture. It is approximately a six-minute walk from Tokura Station on the Shinano Railway.
Its convenient location makes it an easy stop for travelers exploring the historic areas around Chikuma and the former post towns along the Hokkoku Kaido.
Mizukami Funayama Shrine is a remarkable place where history, faith and craftsmanship come together.
From the elegant roofline of its National Important Cultural Property main sanctuary to the extraordinary carvings of rabbits, turtles and dragons, the shrine offers an outstanding example of Edo-period religious architecture. The stone lantern dedicated by 52 women preserves a different, more personal side of history, while the Onbashira Festival continues the traditions of the Suwa faith in the modern era.
For travelers visiting Chikuma City, a walk through the shrine grounds offers a chance to encounter the history of the old Hokkoku Kaido, the culture of Suwa worship and the artistic achievements of Edo-period craftsmen—all in a quiet setting beside the Chikuma River.
