Izumo Taisha Shrine Main Hall

Izumo Daijingu Main Hall: The "Original Izumo" of Kyoto's Kameoka

Nestled at the foot of the sacred Mount Mikage in the Kameoka Basin of Kyoto Prefecture, Izumo Daijingu (出雲大神宮) is one of Japan's most ancient and spiritually significant shrines. Known by the intriguing nickname "Moto-Izumo" (Original Izumo), this shrine claims a history that predates even the famous Izumo Taisha in Shimane Prefecture. Its main hall (honden), designated as an Important Cultural Property of Japan, stands as a superb example of medieval shrine architecture from the late Kamakura to early Muromachi period, bearing witness to over seven centuries of continuous worship and reverence.

As the Ichinomiya (first-ranked shrine) of the ancient Tanba Province, Izumo Daijingu holds a distinguished position in the Japanese spiritual landscape. The shrine enshrines Ōkuninushi-no-Mikoto, the great deity of nation-building and matchmaking, along with his consort Mihotsuhime-no-Mikoto. Today, it draws visitors from across Japan seeking blessings of love, longevity, and good fortune, while architecture enthusiasts come to admire the elegant cypress-bark-roofed honden that Ashikaga Takauji is believed to have renovated in 1345.

Historical Background

According to shrine tradition, the first shrine buildings at this site were erected in 709 (Wadō 2), during the Asuka period. However, the spiritual significance of this location extends far deeper into prehistory. The mountain behind the shrine, Mount Mikage (also called Mount Chitosei), has been venerated as a sacred body (shintaizan) since ancient times, and the presence of late-period kofun burial mounds on the grounds suggests that clans had been conducting worship here long before any formal structures were built.

The shrine's earliest appearance in official records dates to 818, when an entry in the Nihon Kiryaku notes that "Izumo-sha of Kuwata District, Tanba Province, was elevated to the rank of Myōjin." By the mid-Heian period, it was listed in the Engishiki Jinmyōchō as a Myōjin Taisha, confirming its status as one of the most important shrines in the region. In 1292, the shrine's divine rank was elevated to the highest possible grade of Shō-Ichii (Senior First Rank) after a successful rain-summoning ritual.

The shrine's most distinctive claim is its "Moto-Izumo" (Original Izumo) designation. According to a purported passage from the lost Tanba-no-kuni Fudoki, during the Wadō era, Ōkuninushi-no-Mikoto was transferred from this shrine to Kizuki (present-day Izumo Taisha) in Shimane. This stands in contrast to the commonly held view that Izumo Daijingu received its deity from Izumo Taisha. Indeed, until the Meiji era, Izumo Taisha was known as "Kizuki Taisha," and references to "Izumo no Kami" (the deity of Izumo) were understood to mean this shrine in Kameoka rather than the one in Shimane.

The great essayist Yoshida Kenkō immortalized the shrine in Chapter 236 of his Tsurezuregusa (Essays in Idleness), written in the Kamakura period. In the passage, he describes a visit by a monk from Kyoto who was deeply moved by the backward-facing komainu guardian dogs, only to learn from a shrine priest that their unusual positioning was merely the result of children's mischief. This famous literary anecdote confirms that the shrine was already well-known and attracting visitors from the capital by the early 14th century.

The present main hall is believed to have been constructed or substantially renovated in 1345 (Jōwa 1) under the patronage of the shogun Ashikaga Takauji. Three ridge-pole plaques (munafuda) have been discovered within the structure, one of which dates to 1445 and bears an inscription suggesting a connection to Hosokawa Katsumoto, the powerful kanrei (shogunal regent) of the Muromachi bakufu. The honden was designated as a former National Treasure (corresponding to today's Important Cultural Property) on April 1, 1906.

Why It Was Designated an Important Cultural Property

The main hall of Izumo Daijingu was designated an Important Cultural Property for its outstanding value as a medieval Shinto architectural work. Built in the sangensha-nagare-zukuri style (three-bay flowing-roof construction) with a cypress bark (hiwadabuki) roof, the structure exemplifies the refined aesthetic and technical achievements of shrine architecture from the late Kamakura to early Muromachi period.

Several architectural features make the honden particularly noteworthy. The building has a single-bay front porch (kōhai) and features an outer sanctuary (gejin) with an extended front eave, while the inner sanctuary (naijin) and innermost sanctuary (nainaijin) occupy the main body (moya). The design creates a progressive sense of sanctity as one moves from front to back. The outer and inner sanctuary sections are fitted with balustrade-lined verandas (kōran-tsuki en), while waki-shōji partitions at the central pillar of the side walls mark the transition between the public and private zones. The rear half of the main body has no veranda, emphasizing the sacred enclosure of the innermost area. With a footprint of approximately 14 tsubo (about 46 square meters), the structure achieves a remarkable balance between modest scale and architectural dignity.

The honden is also historically significant as tangible evidence of the patronage of Japan's military aristocracy toward Shinto shrines during the turbulent Nanbokuchō period, linking it to the legacy of Ashikaga Takauji and the Muromachi shogunate.

Highlights and Attractions

The Main Hall (Honden)

The cypress-bark-roofed honden is the spiritual and architectural centerpiece of the shrine. Although visitors cannot enter the building itself, it can be viewed from the worship hall (haiden) area through the elegant kirizuma-zukuri (gabled) middle gate. The gentle curve of the flowing roof (nagare-zukuri) and the warm patina of aged cypress bark convey a sense of timeless beauty and reverence.

Mount Mikage and the Iwakura Sacred Rocks

The forested mountain rising behind the shrine is the original object of worship at this site. Mount Mikage remains a forbidden sacred ground (kinsoku-chi) to this day. Within the accessible areas of the shrine grounds, several iwakura (sacred rock formations) can be found, with the large formation directly behind the main hall considered the most spiritually powerful spot in the entire precinct.

Manai-no-Mizu Sacred Spring Water

From the ancient limestone and volcanic rock layers of Mount Mikage, a natural spring known as Manai-no-Mizu flows continuously within the shrine grounds. The water is mineral-rich and has been certified by the Japan Water Quality and Health Research Institute as exceptionally well-balanced and healthful. Visitors often line up with containers to take some of this prized water home, though the shrine recommends boiling it before drinking.

Meoto-Iwa (Husband and Wife Rocks)

A pair of sacred rocks connected by a shimenawa rope, the Meoto-Iwa serves as the focal point for the shrine's famous en-musubi (matchmaking) rituals. Visitors tie red prayer cords around the rocks while praying for romantic blessings and harmonious relationships.

Shiawase Nade-Usagi (Lucky Rabbit Statue)

Located near the first torii gate, this rabbit statue references the myth of the White Rabbit of Inaba, who was rescued by Ōkuninushi-no-Mikoto. Visitors rub the rabbit's body for good fortune, or touch the part corresponding to an area of physical discomfort to pray for healing.

The Haiden (Worship Hall)

The worship hall, built in 1878 in the irimoya-zukuri (hip-and-gable) style with cypress bark roofing, is itself a Registered Tangible Cultural Property. Its open-sided design allows visitors to appreciate the surrounding forest while paying their respects.

Visitor Information

Izumo Daijingu is open year-round, and there is no admission fee to enter the shrine grounds. The shrine office and amulet counter operate from 9:00 AM to 5:00 PM (last reception at 4:30 PM). Free parking is available for approximately 80 vehicles across three lots. The shrine is open to worshippers throughout the day, though the sacred Mount Mikage trail requires borrowing a special sash (tasuki) from the shrine office during operating hours.

The shrine is accessible by taking the Kameoka City Furusato Bus from JR Kameoka Station (approximately 15 minutes) to the "Izumo Jinja-mae" bus stop. By car, take the Kyoto Jūkan Expressway to the Chiyokawa Interchange, then drive approximately 10 minutes. Visitors should note that bus service is limited, so checking schedules in advance is recommended.

Surrounding Attractions

The Kameoka area offers a wealth of cultural and natural experiences that pair well with a visit to Izumo Daijingu. The Hozugawa River Boat Ride, departing from central Kameoka, takes passengers on a thrilling two-hour, 16-kilometer journey through scenic gorges to Arashiyama in Kyoto — a particularly spectacular excursion during the autumn foliage season. The Sagano Romantic Train (Torokko Ressha) offers a parallel experience by rail through the same stunning valley.

Nearby Kuwayama Shrine, another ancient shrine founded in 709, is celebrated as one of Kameoka's finest autumn leaf viewing spots, with approximately 1,000 maple trees surrounding its heart-shaped pond. Anaoji Temple (Anao-ji), one of the 33 temples of the Saigoku Kannon Pilgrimage, features a beautiful Kamakura-period main hall and tranquil gardens. For those interested in local crafts, Tanzan Sake Brewery and Ōishi Sake Brewery offer tastings of traditional Tanba-brewed sake. The Yunohana Onsen hot spring resort, about 20 minutes by car, provides an ideal place to relax after a day of shrine visits and sightseeing.
