History
Haruna Shrine is a Shinto shrine in Japan, located in Takasaki, Gunma, and traditionally associated with the worship of Mount Haruna. Its foundation tradition places the beginning of worship in the reign of Emperor Suizei, while the establishment of its sacred ritual site is dated to 586, the first year of Emperor Yomei’s reign. The shrine venerates Mount Haruna, one of the Three Mountains of Jomo, and its principal deities are Kagutsuchi, a deity of fire, and Haniyama-hime, a deity associated with earth. Water, mountain, agricultural, and other deities are also enshrined.
Early Mountain Worship
According to tradition, a father and son created a sacred enclosure in the mountain for the worship of heavenly and earthly deities. Haruna Shrine first appears in the Engishiki, a tenth-century administrative and ritual compendium completed in 927. There it is listed as a minor shrine in Gunma District among the twelve shrines of the ancient province of Kozuke. The shrine is also formally identified as a Shikinaisha, meaning a shrine included in the Engishiki, and was later recognized as a former prefectural shrine.
Ancient worship of Mount Haruna seems to have involved two related but distinct centers. Worship associated with Ikaho Shrine was approached from the Shibukawa side, while Haruna Shrine was approached from the Takasaki side. The historian Ozaki Kizao connected the first center with the Arima clan and the second with the Kurumamochi clan. This interpretation concerns the organization of the ancient religious landscape rather than a later institutional division.
Buddhist-Shinto Development
Religious practice gradually extended into the mountain interior under the influence of Buddhism, especially esoteric Buddhism. An archaeological area within the grounds is regarded as the remains of monastic buildings and is associated with the opening of a center for mountain ascetic practice during the ninth century. Small gilt-bronze Buddhist images and coins of the Kanpei Taiho type found there reflect this phase of religious activity.
A record compiled around 1028 to 1037 appears to identify Haruna Shrine and indicates that an organized sacred complex already existed. It included a sanctuary, an offering hall, a torii gateway, and inner and outer fences. By 1190, the institution was operating within a Buddhist-Shinto system and was known as Haruna Temple. A document from the provincial administrative office granted the temple estate protection from entry by certain military and police officials. The document’s authenticity has been questioned because it was deposited at the shrine only during the Edo period.
During the medieval period, the institution was also called Iwa Temple, Ishidono Temple, and Iwadono Temple. From this period onward it was known as Mangyo Gongen, a gongen being a deity understood through a Buddhist manifestation. Its assigned Buddhist identity, or honji, was Jizo Bosatsu, a Buddhist protector associated with travelers, children, and the dead. This identification appears in the medieval religious compilation Shinto-shu and on an iron lantern dated 1323.
Medieval Administration
Haruna Temple was governed by a chief priest called the zasu. The family holding this office claimed descent from Fujiwara Michinaga, a powerful Heian-period court noble. Kaichu, who held the office from the late Kamakura period into the early Nanboku-cho period, is associated with a memorial tower dated 1341 in the cemetery of the Haruna mountains.
Kaichu’s daughter’s son, Raiin, defeated rivals during a conflict within the mountain. He then combined the offices of chief priest and executive administrator. Documents from 1374 concern his appointment to the executive position. The institution controlled both estates attached to the chief priest and temple estates. By the fifteenth century, a letter from Kamakura governor Ashikaga Mochiuji indicates that a lay deputy administrator had begun managing the temple estates. Military rulers also appear to have taken control of the institution, and the authority of the zasu was probably abolished or greatly reduced.
During the Warring States period, Uesugi Norifusa, the Nagano clan, the Takeda clan, Sanada Masayuki, and Hojo Ujikuni each issued notices prohibiting violence and disorder within the mountain precinct. These notices show that the religious complex remained an institution whose security and privileges required attention from competing military powers.
Edo-Period Revival and Confraternities
The name Iwadono Temple of Mount Haruna became established during the Edo period. In 1614, the monk Tenkai led a revival of the institution. Komyoji became its scholarly head and Mangyo-in its deputy administrator. The institution was placed within the Tendai Buddhist school, a major Japanese tradition derived from Chinese Tiantai Buddhism, and came under the authority of Kaneiji, a powerful Tendai temple in Edo. Appointed officials often lived elsewhere, so resident caretakers were frequently sent to Mount Haruna.
Five temple compounds operated in the mountain during the Edo period. Guest-preceptor families provided religious services and lodging, helping spread Haruna confraternities through the Kanto and Koshinetsu regions and into Mutsu Province. A confraternity was a voluntary religious association whose members worshipped together, supported offerings, and organized pilgrimages. Haruna confraternities numbered as many as 10,620 groups.
The guest-preceptors maintained territories, visited villages up to four times each year, collected first-offering fees, and distributed talismans. Village members gathered to worship the Haruna deity and usually sent about two representatives on pilgrimage between February and May. Pilgrims stayed at a guest-preceptor’s lodging and returned with talismans; some communities later undertook pilgrimages together.
The confraternity system also supported building and stonework at the shrine. The Edo Daidai Kagura confraternity rebuilt a stone image of Fudo associated with Kurakake Rock. The merchant Tasuke Shiohara donated stone railings along the approach and stone lanterns at Tenjin Pass. Seventy-eight guest-preceptor households were recorded during the Edo period. By 1870, the network comprised twenty-six temple branches and sixty-one households, while fifteen related religious corporations remain registered today.
Separation of Buddhism and Shinto
In 1868, the new government ordered Buddhism and Shinto to be separated at Mount Haruna. In 1870, the newly appointed Shinto priest Toyoaki Hozumi and mountain supervisor Morimura Arai enforced the policy. Buddhist images and ritual objects were removed: wooden images were burned, stone images were thrown into a ravine, and bells were melted down.
The three-story pagoda, then called the Treasure Hall, was also scheduled for partial dismantling, but the work was not carried out. The building therefore retained its pagoda form. In 1880, the Haruna Shrine religious association was established. After the Religious Corporations Act of 1952, the associated religious corporations were placed under the Shinto Taikyo organization, although one later withdrew.
The shrine grounds and surrounding woodland now form a Gunma Prefecture green-environment conservation area. The buildings, archaeological remains, and natural features are protected through national, prefectural, and Takasaki municipal cultural-property designations. Six buildings have national Important Cultural Property status, and the Yatate cedar is a national Natural Monument.
Remains
Haruna Shrine occupies a mountainous precinct associated with Mount Haruna. The approach passes through the western side of the grounds near Shishi Rock, where level terraces were constructed. Tsuzura Rock and Kurakake Rock are among the distinctive formations within the precinct. The surviving buildings, rock features, archaeological area, historic landscape, and woodland together preserve the physical setting of the shrine’s religious development.
Main Shrine Complex
Main Sanctuary and Worship Hall
The principal complex consists of a Kasuga-style main sanctuary, a worship hall in the Irimoya form, and an offering hall joining them. Kasuga-style construction uses a compact sanctuary with a projecting front porch, while the Irimoya form combines a gabled upper roof with hipped lower sections. Together, the buildings create a Gongen-zukuri arrangement, in which the sanctuary and worship hall are connected by an intervening offering hall. The composite structure has a copper-sheet roof, richly colored pillars and beams, and extensive carved decoration. An inscription on the ridgepole dates its construction to 1806.
Sacred Rock and Cave
The massive rock behind the main sanctuary is called the honden, or main sanctuary, by the shrine. The building is joined directly to the rock, and a cave within it houses the sacred object of worship. This arrangement places the central religious object within the mountain formation that defines the precinct.
Associated Shrine Buildings
Founding Ancestors Shrine
The Founding Ancestors Shrine stands to the left of the main complex with its attached plaque-viewing hall. The former originally housed a Buddhist guardian image and was known as the honji hall. It now enshrines three historical deities. The shrine building dates from 1725, and the attached hall was added in 1814 as a place from which sacred music and dance could be viewed.
Kagura Hall
The Kagura Hall was rebuilt in 1764. Kagura is sacred music and dance offered to deities. The hall has a wooden stage open on three sides. Its coffered ceiling carries images of birds and flowers, together with masks used in sacred performances.
Twin Dragon Gate
The Twin Dragon Gate was built in 1856. It is a four-legged gate with an Irimoya roof and copper-sheet covering. Dragon carvings and ink paintings account for its name.
Processional Shrine
The Processional Shrine is traditionally dated to 1859. It is the building where the portable shrine remains during the annual procession. Its surfaces are largely unpainted, with color concentrated mainly on the gable boards and decorative fittings at the gables.
Guardian Gate and Treasure Hall
The Guardian Gate was built in 1847 as an eight-legged gate with an Irimoya roof and standing-seam copper-sheet roofing. It was originally a Nio Gate, a gateway that housed paired Buddhist guardian figures. Those statues were removed during the 1870 separation of Buddhism and Shinto, and guardian figures were installed in 1906.
The three-story Treasure Hall belonged formerly to the Buddhist temple complex and survives in pagoda form. Its planned reduction during the 1870 separation was not carried out, preserving the building’s distinctive appearance within the shrine precinct.
Archaeological and Devotional Remains
Rock-Mountain Site
The Haruna Shrine rock-mountain site contains small gilt-bronze Buddhist images and Kanpei Taiho-type coins. The area is interpreted as the remains of monastic buildings connected with mountain ascetic practice during the ninth century. It provides physical evidence for the Buddhist activities that developed within the mountain interior.
Mirrors and Iron Lantern
Eight Buddhist devotional mirrors associated with the shrine preserve evidence of its Buddhist-Shinto religious history. The oldest is a white-bronze mirror decorated with wisteria, pine, and cranes, bearing an incised image of Eleven-Headed Kannon, a Buddhist bodhisattva associated with compassion, from the early Kamakura period. Another mirror with the same image is broadly dated to the middle of the thirteenth century, and one bears an inscription dated 1281.
The iron lantern dated 1323 carries an inscription referring to Mangyo Gongen and its Buddhist counterpart. It is regarded as the oldest iron lantern in Gunma Prefecture. Its canopy is a later replacement.
Mathematics Votive Plaque
A mathematics votive plaque dedicated in 1811 by Ishida Genkei and his pupils is associated with the Seki school of wasan, or traditional Japanese mathematics. Such a plaque is a sangaku, a record of mathematical problems and solutions offered at a shrine.
Natural Features and Historic Landscape
Yatate Cedar
The Yatate cedar is a natural monument within the grounds. It is approximately 55 meters high and 9.4 meters in circumference. A tradition holds that the sixteenth-century warlord Takeda Shingen shot an arrow into the tree while praying for victory.
Mountain Features and Water Sources
The associated historic landscape includes the site of the processional resting place, the remains of a mountain checkpoint, the stone lantern at Tenjin Pass, and the Mannen Spring monument. Protected geological and botanical features include the Haruna mountain rock vein, a native habitat of Kiyosumi rock fern, and a natural stand of hinoki cypress.
Former Lodging and Administrative Buildings
The Edo-period lodging complex of Ichinomiya, formerly the Hannya branch, survives with its main building and nagaya gate. The Kadokura residence, formerly the Zentoku branch, also retains its main building. The gate of the Suzuki family residence, once the office of the Edo-period deputy administrator, likewise survives. These buildings are registered tangible cultural properties and preserve elements of the religious network that served pilgrims and confraternities.
Ritual Life
Kagura and Annual Festivals
Haruna’s sacred kagura comprises thirty-six performance units, including twenty-one male dances and fifteen shrine-maiden dances. The present form was revived in 1726, although the performance tradition is considered older. The annual cycle includes New Year prayers on January 1 and 3, the Tube-and-Porridge divination rite on January 15, Setsubun on February 3, the opening ceremony for kagura on February 15, and the harvest-prayer festival on February 17.
The spring sequence continues with the hidden April 30 rite of replacing a sacred paper wand on the cleft of the shrine’s sacred rock formation. A Boys’ Festival performance takes place on May 5. On May 8, the sacred object is transferred from the main sanctuary to the Processional Shrine, followed by the return procession and spring festival on May 15. The Chimaki Festival is held on June 5.
Divination and Protection Rites
During the January divination rite, red-bean porridge is cooked with reed tubes submerged in it. The tubes are used to predict the year’s harvest. The result is distributed to villages belonging to the Haruna confraternities, and the porridge is served to visitors.
For the Chimaki Festival, a steamed or boiled rice-flour dumpling is wrapped in three kaya grass leaves and offered before the deities. It is distributed afterward and is traditionally believed to protect against mamushi snakes and, more generally, calamity.
On June 30, the Great Purification rite removes pollution from shrine parishioners. Used ritual paper, cotton, and hemp are wrapped in a straw container and floated down the Haruna River. The road-boundary rite places sacred ropes at the eastern, western, northern, and southern entrances to the Mount Haruna area, while the Fire-Quelling rite sprinkles water over the principal shrine buildings and the roped boundaries.
The autumn festival is held on October 9, followed by the Niiname harvest-thanksgiving rite on November 23. Monthly rites on the first and fifteenth days pray for the safety and prosperity of parishioners and devotees. On December 31, the Great Purification, road-boundary, Fire-Quelling, and Tengu rites are performed. During the Tengu rite, priests secretly scatter 108 grayish rice cakes, each about three centimeters across, from the edge of a shrine building into the forecourt at night. Their color comes from red-bean cooking liquid and soot. A belief that collecting the cakes brings happiness was recorded in 1784.
