This article provides a detailed explanation of everything you need to know before visiting Shinkai Sansha Shrine, from its history and cultural properties to prayers and access information.
Overview and History of Shinkai Sansha Shrine
Historical Role as the Principal Shrine of the Saku Region
Shinkai Sansha Shrine is a historic shrine that has long been revered as the “Principal Shrine of the Thirty-Six Villages of Saku.” A principal shrine is a shrine that enshrines the deities of a particular region, and Shinkai Sansha Shrine has played an important role as the guardian deity of the entire Saku region.
The exact founding date is uncertain, but it is believed to have existed since the Heian period, and there is a legend that Minamoto no Yoritomo repaired and rebuilt the shrine during the Kamakura period. Records also show that Takeda Shingen prayed for victory there during the Sengoku period, and it is known as a shrine with strong faith in war gods.
Main Deity and Divine Virtues
Shinkai Sansha Shrine has three main shrines, each enshrining a different deity.
The East Main Shrine enshrines the main deity, Okihagi-no-Mikoto. Okihagi-no-Mikoto is the grandson of Okuninushi-no-Okami of Izumo and is revered as the pioneering deity of the Saku region. His father is Takeminakata-no-Mikoto of Suwa Grand Shrine, and his mother is Nukisaki-no-Megami (Arafune Daimyojin) of Nukisaki Shrine, the Ichinomiya (first-ranked shrine) of Kozuke Province, making him an important deity connecting Shinano and Kozuke.
The Central Main Shrine enshrines his father, Takeminakata-no-Mikoto. This is a god of martial prowess, also known as the principal deity of Suwa Grand Shrine.
The West Main Shrine enshrines his uncle, Kotoshironushi-no-Mikoto, the god of business prosperity and good fortune, also known as Ebisu.
Furthermore, Homudawake-no-Mikoto, or Emperor Ojin, is also enshrined here, and the shrine is named “Sansha Shrine” (Three Shrines Shrine) for enshrining four deities.
Origin of the Divine Emblem and Shrine Name
The divine emblem of Shinkai Sansha Shrine is the Kajiha (paper mulberry leaf). The paper mulberry has long been considered a sacred plant and is also an emblem indicating its connection to Suwa Grand Shrine.
There are various theories regarding the origin of the shrine name “Shinkai,” but it is believed to derive from the fact that this region was formerly called “Shinkai-go” (Shinkai Village). Another theory suggests that it was named “Shinkai” because it was land newly developed by Okihagi-no-Mikoto.
Nationally Designated Important Cultural Properties and Highlights of the Shrine Grounds
Three-Storied Pagoda (Nationally Designated Important Cultural Property)
One of the greatest highlights of Shinkai Sansha Shrine is the three-storied pagoda. Built in 1515 during the Muromachi period, this pagoda is designated as a Nationally Important Cultural Property.
This three-storied pagoda, approximately 17 meters tall, is characterized by its beautifully balanced form. During the Meiji-era separation of Shinto and Buddhism, while many Buddhist buildings at shrines were destroyed, the pagoda of Shinkai Sansha Shrine was spared destruction thanks to a claim that “this is not a pagoda, but a treasure house.”
Inside the pagoda are enshrined Buddhist statues, making it a valuable cultural asset that conveys the remnants of the era of syncretism between Shinto and Buddhism. Its appearance, harmonizing with the surrounding nature, displays different expressions in each season, boasting exceptional beauty, especially during the seasons of fresh greenery and autumn leaves.
East Main Shrine (Nationally Designated Important Cultural Property)
The East Main Shrine, which enshrines the principal deity Okihagi-no-Mikoto, is also a Muromachi period building and is designated as a National Important Cultural Property, just like the three-story pagoda.
The East Main Shrine, built in the Ikkensha Nagare-zukuri architectural style, is characterized by its intricate carvings and elegant roof curves. Though small in scale, it is a dignified building that well preserves the characteristics of Muromachi period shrine architecture.
The three-story pagoda is positioned behind the East Main Shrine, and together the two create a magnificent landscape. This arrangement is a typical example of shrine architecture from the era of Shinto-Buddhist syncretism and has high architectural historical value.
Worship Hall and Shrine Complex
In addition to the three main shrines—East Main Shrine, Central Main Shrine, and West Main Shrine—the grounds also contain a magnificent Worship Hall. The Worship Hall is where worshippers offer their prayers, providing a solemn and serene atmosphere for quiet reverence.
A spacious approach stretches out in front of the main hall, lined with stone lanterns on both sides. It is especially bustling with worshippers during New Year’s visits and festivals.
Sacred Trees and Nature of the Shrine Grounds
The shrine grounds are dotted with ancient trees estimated to be several hundred years old, creating a sacred atmosphere. The giant cedar trees around the main hall are particularly revered as sacred trees, and their majestic presence leaves a deep impression on visitors.
The vast grounds are surrounded by abundant nature, allowing visitors to enjoy forest bathing. A stroll while listening to the chirping of wild birds and the rustling of trees will refresh both mind and body.
The Forty-Eight Burial Mounds
Scattered throughout the shrine grounds and surrounding area are a group of burial mounds known as the Forty-Eight Mounds. These are believed to have been constructed from the Kofun period to the Nara period, and are valuable historical sites indicating that this region was an important center from ancient times.
The existence of the burial mounds suggests that this area may have been recognized as a sacred place even before the founding of Shinkai Sansha Shrine. As traces of ancient beliefs, it holds significant historical and archaeological importance.
Group of Dōsojin (Roadside Deities)
Numerous Dōsojin statues line the parking lot, welcoming visitors upon arrival. Dōsojin are objects of folk worship, revered as gods of roads and travel, and were collected from settlements surrounding Shinkai Sansha Shrine.
Each of the simple stone statues has a different expression, telling the history of the local people’s faith. Paying respects to these Dōsojin before entering the shrine grounds is one of the pleasures of visiting.

Prayer for Victory
Shinkai Sansha Shrine preserves a prayer written by Takeda Shingen when he prayed for victory in battle. It is said that Shingen considered this area important during his conquest of Shinano Province and prayed for victory at Shinkai Sansha Shrine.
The Shinkai Sansha Shrine, deeply revered as a shrine dedicated to a god of war, also attracted the devotion of Sengoku-era daimyo (feudal lords), and Shingen’s prayer inscription serves as valuable historical evidence of this.
Strategic Importance of the Saku Region
The Saku region was a strategic point connecting Shinano and Kozuke (Gunma Prefecture), making it an important area for the Takeda clan. The Shinkai Sansha Shrine, as the main shrine of the Saku region, is believed to have functioned as a spiritual pillar of regional control.
Shingen’s emphasis on the Shinkai Sansha Shrine was not merely a matter of faith, but also a strategic decision for regional governance.
