This article comprehensively introduces information useful for visiting Sasamori Inari Shrine, including its history, enshrined deities, highlights of the grounds, information on the annual festival, goshuin (shrine stamps), and access methods.
History and Origins of Sasamori Inari Shrine
Founding and Ancient Beliefs
There are various theories regarding the founding date of Sasamori Inari Shrine, but one theory suggests it was established in Tenchō 2 (825) during the Heian period. This period was the time when Kobo Daishi Kukai was active, reflecting the historical context of a time when Buddhism and Shintoism were fused.
The Sasamori Kofun, where the shrine is located, is a keyhole-shaped burial mound estimated to have been constructed in the late 6th to early 7th centuries. Boasting a total length of approximately 80 meters, it is one of the largest burial mounds in the Tomioka-Kanra area. Built on a plateau on the right bank of the Ogawa River (a tributary of the Kaburagawa River), facing west, this burial mound was a central location in the region as the burial site of an ancient powerful clan. The fact that a shrine was built on top of the burial mound indicates that this area was recognized as a sacred place from ancient times.
The Deep Relationship Between the Oda Family and Sasamori Inari Shrine
In the Edo period, the history of Sasamori Inari Shrine underwent a major turning point. In 1642 (Kanei 19), Oda Nobuyoshi, a descendant of Oda Nobunaga’s second son, Nobuo, became the lord of the Obata Domain (20,000 koku).
Initially, the Obata Domain’s headquarters were located within the grounds of Inariyama Higashi Gakuin in Fukushima-juku, along the Shimonita Road (Hime Kaido). This Higashi Gakuin served as the Bettō (the temple managing the shrine) for Sasamori Inari Shrine, and because of this connection, successive lords of the Obata Domain came to deeply revere Sasamori Inari Shrine as the guardian deity of their domain.
The Oda family, descendants of Nobunaga, were a prestigious samurai family, and as a shrine revered by the Oda family for generations, Sasamori Inari Shrine established its status and authority in the region. Under the modern shrine ranking system of the Meiji era, it was ranked as a village shrine and continues to attract the faith of the people as the local tutelary deity.
Deities and Divine Virtues
Main Deity: Ukanomitama-no-kami
The main deity of Sasamori Inari Shrine is Ukanomitama-no-kami. This deity, worshipped nationwide as the principal deity of Inari shrines, is a god of grain appearing in the Kojiki and Nihon Shoki, and is believed to bestow blessings of abundant harvests, business prosperity, and industrial development.
The name “Kura-Inadama” means “the spirit (soul) of rice stored in the storehouse,” and has been revered since ancient times as one of the most important gods in Japanese society, which is based on agriculture. During the Edo period, with the development of commerce, the belief in this deity as a god of business prosperity also spread, and even today, many worshippers visit the shrine to pray for business success.
Enshrined Deity: Toyokiirihiko-no-Mikoto
Sasamori Inari Shrine enshrines Toyokiirihiko-no-Mikoto along with Kura-Inadama-no-Kami. Toyokiirihiko-no-Mikoto was a prince of Emperor Sujin, the 10th emperor, and according to the Nihon Shoki, he was ordered to pacify the eastern provinces and is considered the founder of Kamitsukeno Province (present-day Gunma Prefecture).
Toyokiirihiko-no-Mikoto, enshrined in many shrines throughout Gunma Prefecture, is worshipped as the ancestral deity of regional development and as a god of military success and national peace. The fact that Toyokiirihiko-no-Mikoto is enshrined at Sasamori Inari Shrine indicates that this shrine is not merely a center of Inari worship, but is deeply intertwined with the history of the region.
Divine Virtues and Faith
Sasamori Inari Shrine is believed to possess the following divine virtues:
- Abundant Harvests and Agricultural Prosperity: The original divine virtue of Ukanomitama-no-Kami
- Business Prosperity and Success: A representative benefit of Inari worship
- Family Safety and Good Fortune: Divine virtue as the local tutelary deity
- Protection from Skin Diseases and Healing from Incurable Illnesses: A special miraculous power passed down from ancient times
- Military Success and Protection from Evil: The divine virtue of Toyokiirihiko-no-Mikoto
Of particular note is its reputation for miraculous powers in preventing skin diseases and healing from incurable illnesses. This is thought to be the result of a fusion of Inari worship and local beliefs, and many worshippers visit to pray for good health.
Highlights and Cultural Assets of the Shrine Grounds
Shrine Layout on a Burial Mound
The most distinctive feature of Sasamori Inari Shrine is that the shrine buildings are located on the mound of a keyhole-shaped burial mound. As you proceed along the approach, you can experience the unique layout of the shrine grounds, which takes advantage of the shape of the burial mound.
After passing through the torii gate and climbing the stone steps, you reach the shrine grounds, which utilize the elevation of the burial mound. This location allows you to overlook the surrounding rural landscape from the shrine grounds, giving you a real sense that this area has been an important location with excellent views since ancient times.
Red Torii Gates and the Approach
Red torii gates, a symbol of Inari shrines, line the approach, creating a mystical atmosphere. The vermilion color of the torii gates is characteristic of Inari worship and is considered a color symbolizing protection against evil and abundant harvests.
When walking along the approach to the shrine, it’s important to approach the sacred area slowly, appreciating the tranquil atmosphere that harmonizes with the surrounding nature.
Split Worship Hall (Warihaiden)
A particularly noteworthy feature of the Sasamori Inari Shrine’s architecture is the split worship hall. A split worship hall is a unique type of worship hall with a central section open as a passageway, allowing worshippers to approach the main sanctuary by passing through the center.
This architectural style is commonly found in the Kanto region, especially in Gunma and Saitama prefectures, and is said to be a remnant of the era of syncretism of Shinto and Buddhism. The split worship hall at Sasamori Inari Shrine is magnificently constructed, with impressive carvings and decorations.
Ceiling Paintings and Decorations
Beautiful ceiling paintings adorn the interior of the shrine. These ceiling paintings are believed to have been donated between the Edo and Meiji periods, depicting scenes of flowers, birds, and mythology.
When visiting, paying attention not only to the exterior of the shrine but also to these detailed decorations allows you to feel the faith and artistry of our ancestors. ### Shrine Precincts and Stone Structures
Several shrine precincts and stone structures are arranged around the main shrine building. The old stone lanterns, guardian lion-dogs, and donated stone monuments are evidence of the many people who have worshipped at this shrine throughout its long history.
In particular, the stone structures from the Edo and Meiji periods bear the names and prayers of the donors, making them valuable historical materials that convey the state of faith at that time.
Spring Grand Festival and Hatsuumasai Festival
Spring Grand Festival (Second Sunday of March)
The most important annual event at Sasamori Inari Shrine is the Spring Grand Festival, held every year on the second Sunday of March. This festival is known for its large-scale open-air market, said to be the largest in northern Kanto, attracting many worshippers and tourists from within and outside the prefecture.
On the day of the festival, hundreds of stalls line the shrine grounds and surrounding areas, selling a variety of goods including plants, farming tools, daily necessities, and food. This open-air market is a traditional event dating back to the Edo period and is a beloved local event that heralds the arrival of spring.
During the Shinto rituals, ancient Kagura (sacred dance) and Miko-mai (shrine maiden dances) are performed, and prayers for a bountiful harvest and peace in the community are offered in a solemn atmosphere. The Kitsune-mai (fox dance) is a particularly unique ritual of Inari shrines, featuring a dance mimicking the fox, the messenger of the Inari god.
Hatsuumasai (First Horse Day Festival)
As an important festival of Inari shrines, a festival is also held on Hatsuumasai in February. Hatsuumasai is considered the day the Inari god descended, and festivals are held at Inari shrines throughout Japan on this day.
The Hatsuumasai at Sasamori Inari Shrine attracts many worshippers praying for business prosperity and family safety, and is particularly known for its strong devotion from local shop owners and businesspeople.
About Goshuin (Shrine Seals)
Issuance of Goshuin
Sasamori Inari Shrine offers Goshuin. Goshuin are given by shrines as proof of worship, and in recent years, the number of worshippers who collect Goshuin as a hobby has increased.
Sasamori Inari Shrine’s Goshuin features the shrine’s name and the date of visit written in ink, and stamped with a red seal. Its simple yet dignified design makes it a cherished memento of the visit.
Manners for Receiving a Goshuin (Shrine/Temple Stamp)
When receiving a Goshuin, it is important to observe the following manners:
- Complete your prayers first: A Goshuin is proof of your visit, so please complete your prayers at the main hall first.
- Prepare your Goshuincho (stamp book): Prepare a dedicated Goshuincho and present it open.
- Prepare the offering: Generally, 300 to 500 yen is appropriate; please prepare the exact amount so that no change is given.
- Use polite language: Please politely request, “May I have a Goshuin?”
- Don’t forget to express gratitude: When you receive it, say “Thank you.”
A Goshuin is not a stamp rally; it is an important way to forge a connection with the shrine. A shrine is not a shop, so it is important to visit with respect, valuing manners and morals.
Hours of Operation at the Shrine Office
Goshuin are only available during the hours when the shrine office is open. Since the temple may be unattended at times, if you want to be sure to receive a Goshuin (temple/shrine stamp), we recommend visiting on festival days such as the annual grand festival or after contacting them in advance.
