Tsumashina Shrine is a historic Shinto shrine located in a quiet residential area of Minami-Nagano, Nagano City. It is traditionally regarded as one of the Three Guardian Shrines of Zenkoji Temple, together with Takei Shrine and Yutaka Shrine, and is also counted among the Seven Shrines associated with Zenkoji.
The shrine has long been closely connected with the religious history of the Zenkoji area. It is also recognized as a historic Shikinaisha, a shrine listed in the ancient Engishiki records, and was formerly designated as a prefectural shrine under Japan’s prewar shrine ranking system.
Tsumashina Shrine stands southwest of Zenkoji Temple and just north of the Nagano Prefectural Government complex. Although it is surrounded by the urban landscape of Nagano, stepping through the shrine grounds brings visitors into a remarkably peaceful and secluded atmosphere.
The area south of the shrine has long been known as a prestigious residential district. The place name Tsumashina Shrine South has also appeared frequently in local real-estate reports, reflecting the area’s long-standing connection with the central part of Nagano City.
The principal deity of Tsumashina Shrine is Yasakatome-no-Mikoto, who is traditionally regarded as the wife of Takeminakata-no-Kami, the principal deity of Suwa Taisha. The worship of this divine couple is closely connected with the Suwa tradition and is also reflected at several other shrines around Zenkoji, including Takei Shrine, Yutaka Shrine, and Mizuchi Taisha.
The shrine also enshrines Takeminakata-no-Mikoto and Hikowake-no-Mikoto. There are several interpretations concerning the identity of these deities. One tradition holds that they represent different aspects of Takeminakata Tomi-no-Mikoto Hikono-Kamiwake-no-Kami, while another identifies Hikowake-no-Mikoto as a descendant of Takeminakata-no-Kami.
The exact date of the shrine’s foundation is unknown, but its name is traditionally associated with the worship of the wife of Takeminakata-no-Kami. One interpretation connects the shrine with the ancient Minouchi-no-Kami mentioned in records dating to the reign of Emperor Jito in the late seventh century.
According to local tradition, Takeminakata-no-Kami was defeated by Takemikazuchi-no-Kami in a legendary conflict and traveled north from Izumo into Shinano. After following the Chikuma River upstream, he reached the area around present-day Nagano City, where he encountered Takemikazuchi again.
During this journey, his wife is said to have hidden from the fighting in the area that later became known as Tsumashina. The place name is therefore traditionally interpreted as being connected with the presence of the divine wife.
Another part of the tradition tells that Takeminakata was wounded in another confrontation and escaped to Ikushimatarushima Shrine in present-day Ueda. After recovering, he eventually continued toward the region that is now Suwa.
The shrine first appears in historical records in 860, when the Nihon Sandai Jitsuroku records that the deity known as Tsumashina-no-Chijin was granted a higher divine rank. This suggests that the shrine was already an important object of local worship at the time.
Its historical significance is further reflected in the Engishiki, a major compilation of ancient Japanese laws and rituals completed in the early tenth century. Tsumashina Shrine is listed there as a Shikinaisha of Minochi District in Shinano Province.
Several ancient burial mounds known as Otakarazuka were once said to have stood behind the main sanctuary. The name of the nearby Takarazuka Street is traditionally connected with these mounds.
This has led to the possibility that the shrine’s origins may be related to ancient rituals associated with burial mounds. The character “ka” or “shina” (科) in place names such as Sarashina, Hanashina, Hoshina, and Nishina is also characteristic of the historical geography of Shinano.
Archaeological remains have also been discovered around the Nagano Prefectural Government area, including the Kencho archaeological site, where evidence of an ancient settlement has been found. Obsidian arrowheads have reportedly been discovered within the shrine grounds, adding another layer to the area’s long human history.
During the Edo period, the Matsushiro Domain granted Tsumashina Shrine an estate of two koku of rice. The shrine continued to attract the devotion of people in the surrounding area.
In 1873, it was classified as a Go-sha, or village-level shrine, under the modern shrine ranking system. In 1931, it was elevated to the status of a Prefectural Shrine.
The main sanctuary is built in the traditional Ichimasha Nagare-zukuri style, characterized by its gracefully curved roof. It stands on elevated ground behind the worship hall, giving the inner sanctuary a dignified and secluded presence.
Other buildings on the grounds include the worship hall, a building for the recitation of Shinto prayers, a sacred-food preparation hall, and the shrine office. Together, these buildings preserve the atmosphere of a traditional community shrine that continues to serve local worshippers.
Several subsidiary shrines can also be found within the grounds. These include Tenjin Shrine, associated with learning and academic success; Shotoku Shrine, dedicated to Prince Shotoku; Suijin Shrine, dedicated to a deity of water; and Yosan Shrine, associated with sericulture, an industry that once played an important role in the region.
One of the most important traditions associated with Tsumashina Shrine is the Gochin Bashira Festival, a ritual held every six years in the Year of the Tiger and the Year of the Monkey. It is modeled on the famous Onbashira tradition of Suwa Taisha.
Tsumashina Shrine takes turns hosting the festival with Takei Shrine, Yutaka Shrine, and Mizuchi Taisha. Large sacred pillars are erected within the shrine grounds, and the event brings together local communities in a powerful expression of regional tradition.
On the evening of August 26 each year, Tsumashina Shrine holds the Misayama Festival. Ears of silver grass and chopsticks are offered before the deities while prayers are made for children’s healthy growth, family safety, and prosperity in business.
On the following morning, a traditional belief holds that eating azuki bean porridge prepared using chopsticks made from silver grass will bring good health throughout the coming year. The custom remains an important part of the area’s local religious culture.
Among the shrine’s cultural treasures is a large ema votive painting depicting a Gochin Bashira festival procession. Created in 1860, the painting records the procession held to commemorate the rebuilding of Tsumashina Shrine after the devastating Zenkoji Earthquake of 1847.
Designated as a tangible cultural property by Nagano City, the painting provides a valuable glimpse into the religious customs and community life of nineteenth-century Nagano.
A fascinating local legend concerns a stone known as Raiden’s Strength Stone. A river once flowed southeast of the shrine, and a stone bridge called Takei Bridge crossed it. When local people struggled to move the heavy bridge, the legendary sumo wrestler Raiden Tameemon is said to have happened to pass by while visiting Zenkoji on tour.
According to the story, Raiden used his extraordinary strength to move the bridge in a single effort. The stone became associated with the wrestler, and another local tradition says that children who stand on it will grow up strong and healthy.
Another small shrine within the grounds, Yajima Inari Shrine, is connected with a touching local tale about a blind biwa musician named Yajima Ichirobei, who lived in the nearby Iwasecho area.
According to the story, a fox helped the musician, and after the fox died, Ichirobei buried it and established a small Inari shrine in gratitude. The shrine is said to have been established in 1800 and was later moved into the grounds of Tsumashina Shrine in 1896, where it continues to be cared for by the local community.
The grounds also contain small shrines and monuments dedicated to Matsuo Shrine, Konpira Shrine, Mitsumine Shrine, Tenjin Shrine, and Sarutahiko Okami. Together, these sites illustrate the diversity of traditional beliefs that have been preserved within the community.
Tsumashina Shrine offers a quieter side of Nagano’s religious heritage. Unlike the major tourist attractions around Zenkoji, the shrine retains the atmosphere of a neighborhood place of worship, allowing visitors to experience a more intimate connection with local history and tradition.
Its combination of ancient mythology, archaeological traces, Suwa-related religious traditions, historic festivals, and local legends makes the shrine particularly interesting for travelers who want to look beyond the most famous sights of Nagano.
Because of its historical connection with Zenkoji and its location within central Nagano, Tsumashina Shrine can be incorporated into a walking itinerary around the Zenkoji area. Visiting the shrine together with Takei Shrine and Yutaka Shrine provides a broader perspective on the network of shrines that has traditionally protected and supported the religious center of Zenkoji.
For travelers interested in Japanese mythology, traditional Shinto, local festivals, and the layers of history hidden within an urban landscape, Tsumashina Shrine offers an opportunity to encounter a quieter and deeply rooted side of Nagano.
