Niyama Shrine is a historic Shinto shrine located in Kanzaki Town, Kanzaki City, Saga Prefecture. It has long been known by several names, including Hiyoshi Shrine, Hiyoshi-sha, and Sannō Gongen. With a history extending back more than a thousand years, it has served as an important center of local religious faith and has received support from the lords of the Saga Domain and generations of local residents.
The shrine formerly held the status of a prefectural shrine under the prewar shrine classification system. Its grounds preserve historical buildings, cultural properties, and a traditional religious heritage closely connected with the former Buddhist temple complex of Niyama Gokokuji.
The origins of Niyama Shrine date back to 729, when a deity from Matsuo Taisha was enshrined in this area. This is regarded as the beginning of the shrine’s history.
In 844, the Buddhist monk Ennin, also known as Jikaku Daishi, returned from Tang China and reportedly discovered a plaque bearing the inscription “Hiyoshi Shrine” buried in the ground. He reported the discovery to the imperial court, and Emperor Ninmyō regarded it as a sign of divine significance. The emperor then ordered that a deity from Hiyoshi Shrine on Mount Hiei be enshrined together with the existing deity.
According to tradition, the name Niyama was created by combining the character “Ni” from Emperor Ninmyō’s name with “Hi,” taken from Hiyoshi Shrine on Mount Hiei. This story is closely associated with the shrine’s identity and its historical connection with the religious traditions of Mount Hiei.
For much of its history, Niyama Shrine existed alongside the Buddhist temple complex known as Niyama Gokokuji. This arrangement reflected the traditional Japanese practice of Shinto-Buddhist syncretism, in which shrines and Buddhist temples were closely connected and religious practices were shared.
Traces of this history can still be seen along the shrine approach. The plaque on the first torii gate bears the name “Sannō Gongen,” while the second torii carries the inscription “Hiyoshi Shrine.” These inscriptions preserve the memory of the shrine’s earlier religious identity.
Throughout its history, Niyama Shrine received donations of shrine estates and agricultural fields. Many historical documents were lost during periods of warfare, but one of the oldest surviving records dates to 1361. It records a land donation in Kanzaki-shō by a person named Kōchō.
Other powerful figures, including Ōuchi Norihiro and Shōni Masasuke, also confirmed the shrine’s landholdings. These records indicate that the shrine possessed considerable influence and was supported by important political and regional figures.
In 1559, the shrine buildings were destroyed during the invasion led by Ōtomo Sōrin. The shrine was subsequently rebuilt with the support of Nabeshima Naoshige and his son Nabeshima Katsushige, who played important roles in the establishment and development of the Saga Domain.
During the Edo period (1603–1868), Niyama Shrine continued to prosper under the protection of the Saga Domain. The domain provided financial support for repairs, and the lord sometimes sent representatives to attend religious ceremonies on his behalf. These practices demonstrate the importance attached to the shrine by the ruling family.
In 1674, Nabeshima Mitsushige, the lord of the Saga Domain, donated a torii gate to the shrine. This contribution is another indication of the close relationship between the shrine and the domain’s ruling family.
In 1871, the government’s policy of separating Shinto and Buddhism led to the formal separation of Niyama Shrine from Niyama Gokokuji. The shrine was renamed Hiyoshi Shrine, and its religious organization was reorganized in accordance with the new system.
In 1916, it was elevated to the status of a prefectural shrine. Between 1910 and 1911, thirteen shrines within Niyama Village and Shiratsunao Shrine were merged into the institution. In October 1911, the shrine adopted its present name, Niyama Shrine.
Niyama Shrine is particularly well known for Onda Mai, a traditional ritual dance associated with rice cultivation and prayers for an abundant harvest. It is designated as an Important Intangible Folk Cultural Property of Saga Prefecture.
The dance is performed as part of the Ōonda Festival, which takes place once every twelve years in the Year of the Monkey. The festival lasts for thirteen days and begins on the first Day of the Monkey in the traditional calendar. According to tradition, Onda Mai was introduced from Hiyoshi Taisha during the Heian period.
During the performance, participants enact the movements of rice planting accompanied by traditional songs known as Onda-uta and musical performances. A total of 48 performers take part in the dance, recreating the work and ceremonies associated with rice cultivation.
In the past, the performers were men born in the Year of the Monkey. Today, the tradition is preserved and passed on by the Onda Mai Preservation Society, which works to ensure that this distinctive folk performance continues for future generations.
At the Niōmon Gate near the entrance to the shrine approach stand two imposing wooden statues of Kongō Rikishi, the traditional Buddhist guardian figures. The statue on the right represents Agyō, with its mouth open, while the statue on the left represents Ungyō, with its mouth closed.
Both statues are more than three meters tall and are regarded as among the oldest surviving Niō guardian statues in Kyushu. Their creation may date back as far as the Heian period, giving them considerable historical and artistic value.
The Niyama Shrine Documents are a collection of historical records handed down by the shrine. They contain information about the shrine’s development, land donations, and relationships with important historical figures.
These documents are valuable sources for understanding not only the history of Niyama Shrine but also the broader history of Kanzaki City and the surrounding region.
The Niōmon Gate is believed to have originally been the main gate of Niyama Gokokuji. It is estimated to have been constructed during the Kanbun era, between 1661 and 1673, and features the distinctive structure of an eight-legged gate.
The roof was renovated with copper sheeting in 1980. Although the gate is now managed by Niyama Shrine, its origins reflect the close historical relationship between the shrine and the former Buddhist temple complex.
Several smaller shrines stand within the grounds of Niyama Shrine. These include Matsuo-gu and Matsumori Inari Shrine, each of which has its own history and traditions of worship.
These subsidiary shrines add to the religious character of the grounds and reflect the diverse forms of local faith that have been maintained over many generations.
One of the notable natural features of the shrine grounds is the large camphor tree known as the Niyama Shrine Camphor Tree. It is designated as a Natural Monument by Saga Prefecture.
The enormous tree has grown over many generations and is cherished by local residents as a guardian of the shrine. Its impressive size and long history make it an important part of the natural and cultural landscape of Niyama Shrine.
As visitors walk up the approach to Niyama Shrine, they can also visit the former residence of Genpaku Itō. This is the birthplace of Genpaku Itō, a physician who contributed to the introduction and development of Western medicine in Japan.
The former residence is designated as a Historic Site by Saga Prefecture and provides an opportunity to learn about an important figure in the history of Japanese medicine.
Immediately south of Niyama Shrine stands Niyama Jizōin, a Tendai Buddhist temple with a long history of its own. The temple was once part of the Niyama Gokokuji complex, which was closely associated with the shrine before the separation of Shinto and Buddhism in the Meiji period.
Today, the shrine and temple remain neighboring historical sites, allowing visitors to explore two important aspects of the area’s religious heritage in one visit.
Kuen-an is located to the west of Niyama Shrine. This historic residence and garden was developed during the Meiji period and is especially famous for its beautiful autumn foliage.
When the leaves turn red and gold, the garden attracts many visitors who come to enjoy the seasonal scenery. Its location near the shrine and temple makes it a particularly attractive destination for those wishing to explore the historical and cultural landscape of Niyama.
Niyama Shrine is a historic place of worship where more than a thousand years of religious tradition remain visible in its buildings, cultural properties, and natural surroundings. Its origins are connected with the arrival of a deity from Matsuo Taisha, the traditions of Hiyoshi Shrine on Mount Hiei, and the historical relationship between Shinto and Buddhism in Japan.
The shrine is particularly notable for Onda Mai, a traditional rice-planting dance performed once every twelve years, as well as its Niōmon Gate, imposing guardian statues, historical documents, and sacred camphor tree.
With Niyama Jizōin Temple, the former residence of Genpaku Itō, and Kuen-an Garden nearby, the area offers a rewarding combination of religious history, cultural heritage, and seasonal natural beauty. Visitors can enjoy a peaceful walk while discovering the long history of Kanzaki and the traditions that continue to shape the local community.
