Deities and Divine Virtues

The main deity of Akagi Shrine is Akagi Daimyojin. Akagi Daimyojin has been worshipped since ancient times as the god of Mount Akagi and Lake Akagi, and as a guardian deity of the people. Several other deities, including Toyokiirihiko-no-Mikoto, are also enshrined.
Toyokiirihiko-no-Mikoto was a prince of Emperor Sujin (the 10th emperor) and is believed to have been tasked with pacifying the eastern provinces. He is revered as the pioneering deity of Kōzuke Province (present-day Gunma Prefecture).
Deities Enshrined Together
The current Akagi Shrine enshrines deities from various shrines that were previously located on different peaks of Mount Akagi:
- Toyouke Shrine (Onuma-bata)
- Itsukushima Shrine (Kotorigashima)
- Takao-no-kami Shrine (Kurohimeyama Summit)
- Other shrines on different peaks of Mount Akagi
These shrines were enshrined together at the current location in 1970 (Showa 45) when the shrine building was relocated.
The Legend of Akagi-hime and Women’s Wishes
Akagi Shrine is associated with the legend of Akagi-hime, recorded in the “Shinto-shu” (Collection of Shinto). According to this legend, a goddess named Akagi-hime, who was summoned to Akagi Daimyojin, is enshrined here, and it is said that women’s wishes will surely be granted when they pray to this goddess.
For this reason, Akagi Shrine is known as a particularly popular power spot for women, attracting many female worshippers with wishes for matchmaking, successful relationships, fertility, and safe childbirth.
The Blessing of Water and Abundant Harvests
The water flowing from the summit of Mount Akagi has given life to living things, nourished fields, and produced abundant food. For this reason, Akagi Shrine is also worshipped as a deity of abundant harvests, business prosperity, and good fortune.
History of Akagi Shrine
Founding and Ancient Records
The founding date of Akagi Shrine is unknown, but it is a shrine with a very long history. Documentary records indicate that sacred treasures were dedicated in Daido 1 (806), indicating that it existed as an important shrine at least in the early Heian period.
The Engishiki Jinmyocho (compiled in 927) lists it as “Akagi Shrine, Seta District, Kōzuke Province, Myōjin Taisha,” indicating that it was recognized by the imperial court as a shrine of the highest rank, Myōjin Taisha.
Development of Akagi Mountain Faith
Akagi Mountain has been revered since ancient times as a “mountain where gods reside” and has been an object of mountain worship. Numerous branch shrines of Akagi Shrine were established, mainly in the Kanto region, and Akagi faith spread widely. Especially during the Edo period, Akagi religious associations were organized throughout the Kanto region, and many believers made pilgrimages to Akagi Mountain.
Changes in the Modern Era
With the Meiji-era separation of Shinto and Buddhism, the religious facilities on Akagi Mountain, which had previously been a syncretic blend of Shinto and Buddhism, were reorganized. Under the modern shrine ranking system, it was classified as a village shrine, but its historical importance remained unchanged, and it continued to exist as a center of regional faith.
The Great Relocation in the Showa Era
In 1970 (Showa 45), due to the dilapidation of the shrine buildings, Akagi Shrine, which had previously been located in Daido, was relocated to its current location. At this time, as mentioned above, the various peak shrines within Akagi Mountain were also merged, resulting in the current form.
The site of the original shrine in Odō still remains today, making it an important historical site that allows us to reflect on the history of Akagi Shrine.
Highlights of the Shrine Grounds
Vermilion-Painted Shrine
The most distinctive feature of Akagi Shrine is its beautiful vermilion-painted shrine built on the shore of Lake Ōnuma. The vibrant vermilion, contrasting beautifully with the deep green surroundings of the lake, captivates visitors. Especially during the seasons of fresh greenery and autumn leaves, the vermilion of the shrine harmonizes with the natural colors, creating a breathtaking spectacle.
The shrine faces Lake Ōnuma, and its reflection on the lake’s surface is also beautiful, making it a popular photo spot for many photography enthusiasts.
Ōnuma (Lake Ōnuma)
Lake Ōnuma, one of the sacred objects of worship at Akagi Shrine, is a crater lake of Mount Akagi, with a circumference of approximately 4.2 kilometers and a maximum depth of approximately 20 meters. Located at an altitude of 1,340 meters, it is also known for completely freezing over in winter.
A walking path is maintained along the lakeshore, allowing visitors to enjoy a stroll. You can also enjoy leisure activities such as boating and smelt fishing, appreciating the natural beauty of the area throughout the seasons.
Konuma Lake and Kotorigashima Island
Konuma, located a short distance from Onuma Lake, is also considered a sacred site. Konuma Lake has a small island called Kotorigashima Island, where Itsukushima Shrine was once enshrined (now merged with Akagi Shrine). Konuma Lake has a quieter, more mystical atmosphere than Onuma Lake and is popular as a power spot.
Kurohisan Mountain
The summit of Kurohisan (1,828 meters above sea level), the highest peak of Mount Akagi, once housed Takao-no-kami Shrine. Although now merged with Akagi Shrine, climbing Kurohisan is often done in conjunction with a visit to Akagi Shrine, and the view from the summit is known as a spectacular panorama of the Kanto Plain.
The trailheads are concentrated around Lake Onuma, and you can enjoy hiking starting from Akagi Shrine. ## Annual Festivals and Events
