Yubuku Shrine is a historic Shinto shrine in Hakoshimizu, Nagano City. For centuries, it has been closely associated with the religious life of the Zenkoji area and is traditionally regarded as one of the Three Guardian Shrines of Zenkoji, together with Takei Shrine and Tsumashina Shrine. It is also counted among the Seven Shrines associated with Zenkoji.
The shrine was formerly classified as a Go-sha, or village-level shrine, and continues to be an important place of worship for local residents. Despite its location close to the major tourist attractions of central Nagano, its grounds retain a peaceful and deeply spiritual atmosphere.
Yubuku Shrine stands only a few minutes’ walk northwest of the main hall of Zenkoji Temple. Surrounded by a quiet residential neighborhood, the shrine offers a tranquil contrast to the busy streets around Zenkoji.
The principal deity is Takeminakata-no-Kami, the same deity worshipped at Suwa Taisha. Along with Takei Shrine, Tsumashina Shrine, and Takeminakata Tomi-no-Mikoto Hikowake-no-Kami Shrine, also known as Mizuchi Taisha, Yubuku Shrine is associated with the Suwa tradition of Shinto worship.
Yubuku Shrine participates in a traditional Onbashira Festival held every six years, in the Year of the Tiger and the Year of the Monkey. The festival rotates among four shrines: Yubuku Shrine, Takei Shrine, Tsumashina Shrine, and Mizuchi Taisha.
The tradition is modeled on the famous Onbashira Festival of Suwa Taisha. During the ceremony, enormous sacred pillars are erected within the shrine grounds. The pillars symbolize the renewal of the sacred space and serve as an important expression of devotion to the deities.
A large Onbashira can be seen standing on the grounds of Yubuku Shrine, providing a visible reminder of the shrine’s close connection with the Suwa tradition.
Yubuku Shrine uses a kaji leaf as its sacred crest, the same distinctive symbol associated with Suwa Taisha. The kaji leaf has traditionally been regarded as a sacred emblem representing divine protection.
The shrine’s influence can even be seen in the local educational community. Nearby Nagano Nishi High School incorporates a crescent moon embracing a kaji leaf into its school emblem, reflecting the cultural connection between the shrine and the surrounding community.
One of the most intriguing features of Yubuku Shrine is a memorial site known as Otakarazuka. It is traditionally associated with Honda Yoshimitsu, the figure regarded in tradition as the founder of Zenkoji Temple.
A large stone believed to mark his grave is enshrined within the shrine grounds. In 1921, the stone was reportedly discovered together with human bones beneath the grounds, leading to the belief that it could be connected with Honda Yoshimitsu.
A dedicated mausoleum was completed in 2007, and the stone is now respectfully enshrined there. The site offers visitors an opportunity to explore the traditions and legends surrounding the origins of Zenkoji from a different perspective.
The shrine grounds are also home to three enormous keyaki trees, or Japanese zelkova trees, estimated to be approximately 700 to 900 years old. In 1967, all three were designated as Natural Monuments of Nagano City.
Two of the trees stand on either side of the approach in front of the main sanctuary, creating a natural gateway to the sacred space. Their massive trunks and branches convey a sense of time stretching far beyond the lives of individual generations.
The third keyaki stands on the western side of the grounds. Together, these ancient trees form one of the most impressive natural features of Yubuku Shrine.
Yubuku Shrine occupies a traditional position northwest of Zenkoji, an area regarded as its Ura-kimon, or spiritually important rear direction. According to local tradition, placing a guardian shrine in this direction helped protect Zenkoji and the surrounding community.
The shrine historically served the parishioners living in an area extending roughly 15 town blocks west of the main approach to Zenkoji. Takei Shrine served the corresponding area to the east, illustrating how the three guardian shrines were closely connected with the religious life of the city.
One of the most significant events in the shrine’s history was the Zenkoji Earthquake of 1847. The powerful earthquake destroyed the shrine buildings and left the site in a severely damaged condition.
Local parishioners and residents worked to restore the shrine, and the present main sanctuary and worship hall were rebuilt in 1862. These buildings have continued to preserve the shrine’s traditional character through the generations.
In 1921, human bones were reportedly discovered beneath the Otakarazuka, leading to its association with the traditional grave of Honda Yoshimitsu. In 1967, the three ancient keyaki trees were designated as Natural Monuments of Nagano City. In 2007, the mausoleum dedicated to Honda Yoshimitsu was completed and the Otakarazuka stone was formally enshrined.
Yubuku Shrine offers more than a traditional shrine experience. Its grounds bring together Shinto belief, the history of Zenkoji, Suwa traditions, local legends, and ancient trees in one peaceful setting.
The Onbashira tradition provides a connection to the distinctive religious culture of the Suwa region, while the Otakarazuka introduces visitors to legends surrounding the origins of Zenkoji. The enormous keyaki trees, meanwhile, provide a tangible reminder of the centuries of history that have passed beneath their branches.
Because Yubuku Shrine is located just northwest of Zenkoji, it can easily be included in a walking itinerary around the temple district. After visiting the grand and well-known Zenkoji complex, a short walk to Yubuku Shrine offers a quieter experience of the area’s local religious culture.
For travelers interested in Japanese mythology, traditional Shinto, sacred trees, and the historical relationship between shrines and temples, Yubuku Shrine provides a fascinating glimpse into the spiritual landscape of Nagano.
Yubuku Shrine has continued to stand quietly beside Zenkoji for centuries, preserving traditions that connect ancient beliefs with the everyday life of the local community. From the sacred Onbashira to the legendary Otakarazuka and the towering keyaki trees, every part of the shrine grounds tells a story.
When visiting Zenkoji, consider walking north to this peaceful shrine. Away from the crowds, you can experience a different side of Nagano’s religious heritage and spend a quiet moment surrounded by history, nature, and local tradition.
