Deities and Divine Virtues of Marugo Shrine
The enshrined deity of Marugo Shrine is Takeminakata-no-Mikoto. Takeminakata-no-Mikoto is a deity enshrined at Suwa Grand Shrine in Shinano Province (present-day Nagano Prefecture), and is known as the god of martial prowess and agriculture. He appears in the Kojiki (Records of Ancient Matters) as a son of Okuninushi-no-Mikoto, and has been worshipped as a god who demonstrated military strength in the myth of the transfer of the land.
Suwa faith spread throughout Japan from the medieval period onward, primarily among the samurai class, and many Suwa shrines were established in Chiba Prefecture. Marugo Shrine is one such example; it is believed to have been founded in this location as Suwa Daimyojin because the Maru clan, a local samurai group, embraced Suwa faith.

- Abundant Harvests and Protection of Agriculture: As a god of agriculture, many worshippers visit to pray for a bountiful harvest.

History of Marugo Shrine
Founding during the Yōrō Era and the Reverence of the Maru Clan
Marugō Shrine is said to have been founded during the Yōrō era (717-724). Initially called “Suwa Daimyōjin” or “Suwa Shrine,” it was revered by the Maru clan, who ruled this region. The Maru clan was a samurai group that served as district magistrates in Awa Province and held power in the southern Bōsō region from the late Heian period to the Kamakura period.
Records show that Marumoto Toshi constructed the shrine during the Juei era (1182-1185). This period coincided with the Genpei War, and it is believed that the Maru clan sided with the Minamoto clan. Since Suwa worship was highly valued as a guardian deity for samurai, it was natural for the Maru clan to respectfully worship it as their tutelary deity.
After the Fall of the Maru Clan and the Satomi Clan Era
The Maru clan is believed to have fallen during the Muromachi period, but afterwards, this region came under the control of the Sengoku daimyo, the Satomi clan. The Satomi clan also valued Marugo Shrine as the “Great Shrine of Marugo” and protected it as the main shrine of the region. As the main shrine of the 14 villages of Marugo, it became a place of worship that attracted a wide range of followers.
Name Change in the Meiji Era
In 1869 (Meiji 2), with the separation of Shinto and Buddhism and the establishment of the shrine ranking system, the shrine’s name was changed from “Suwa Shrine” to “Marugō Shrine.” This name originates from the local place name “Marugo” (the village of the Maru clan), and is thought to emphasize the shrine’s connection to the community. This name change led to the establishment of the current name, “Marugo Shrine.”
Highlights and Cultural Assets within the Shrine Grounds
The 800-Year-Old Sacred Cedar
The greatest highlight of Marugo Shrine is the 700-800 year old cedar tree that stands tall within the grounds. This sacred tree is designated a natural monument of Minamiboso City (formerly Maruyama Town) and is carefully protected as a living witness to the shrine’s long history.
Its trunk circumference reaches several meters, and its imposing presence is overwhelming when you look up at it. Based on its age, it is thought to have been planted between the Kamakura and Muromachi periods, and it may have watched over the shrine since the time the Maru clan built the shrine buildings. This magnificent cedar, standing out even in the tranquil cedar forest, gives visitors a sacred atmosphere.
Steep Approach and Three Torii Gates
The approach to Marugo Shrine is known for its steepness. The slope near the second torii gate is particularly steep, surprising visitors. After climbing this steep slope, the third torii gate appears, and beyond that, the landscape transforms into a serene cedar forest, a sacred area.
This change in topography symbolically represents the transition from the secular world to the sacred realm, encouraging visitors to shift their mindset. Those with less confidence in their physical abilities are advised to climb slowly, taking breaks as needed.
Serene Cedar Forest and Shrine Atmosphere
After passing through the third torii gate, the shrine grounds are enveloped in a cedar forest with trees hundreds of years old. The quiet space, bathed in dappled sunlight, truly embodies the atmosphere of a sacred area. It’s also gaining attention as a power spot where one can escape the hustle and bustle of the city and find peace in nature.
Especially in the early morning and evening, the atmosphere is even more mystical, making it ideal for photography. Entry to the shrine grounds is free, and you can easily find your way there using a map app.
Main Shrine and Subsidiary Shrines
The main shrine is believed to have been rebuilt several times since the time of the Maru and Satomi clans. The current shrine building is relatively simple in structure, but it possesses the dignity befitting a center of local faith. Quietly offering your prayers at the worship hall, you can feel the prayers accumulated over a long history.
