Tsushima Shrine Mikoshi Hall

Tsushima Shrine Mikoshi-den: A Showa-Era Portable Shrine Hall in Sanuma

Step into the precincts of Tsushima Shrine in Tome City and your eye will be drawn first to the densely carved main hall facing north, an unusual orientation for a Shinto shrine. Just beside it stands a smaller, quieter structure: the Mikoshi-den, the portable shrine hall. It does not announce itself the way the main hall does, yet without it the shrine's most important annual event could not take place. Inside rests the mikoshi that is shouldered through the streets of Sanuma every July, when the town turns out for what residents simply call Gotennō-san no matsuri — the festival of "Lord Tennō."

The Mikoshi-den dates from 1928 (Shōwa 3) and was completed during the long reconstruction that followed the catastrophic Sanuma fire of 1912. In 2024, together with the main hall and worship hall, it was added to the national register of tangible cultural properties.

A Hall Born from One Donor and One Railway

Most shrine buildings are paid for by parishioners as a collective effort. The Mikoshi-den at Tsushima Shrine is different. Both the hall and the mikoshi it shelters were donated in 1928 by a single benefactor: Satō Tetsurō, who ran the Sanuma Railway. The railway was a short local line that connected Sanuma to the wider Tōhoku network during the early twentieth century, the brief age when private narrow-gauge railways carried rice, lumber, and people across rural Miyagi.

The donation tells you something about Sanuma in the late 1920s. The Meiji 45 (1912) fire had reduced the shrine to ash — the main hall, worship hall, the Zuijin gate, four subsidiary shrines, all gone. Reconstruction stretched from 1918 to 1928, a full decade. By the time the worship hall was rebuilt in 1923, the town was still missing one essential piece: a dignified home for the mikoshi. Satō stepped in to provide it, and in doing so closed the long reconstruction. The Mikoshi-den is, in effect, the building that marked the end of the rebuilding.

Why a Shrine That Faces North

To understand why the Mikoshi-den matters, you have to understand the shrine itself, which is not quite like any other in Miyagi. The original Tsushima Shrine stood north of here at a place called Tenkeizan, founded as a branch of the great Tsushima Shrine in Owari (today's Aichi) by order of Minamoto no Yoritomo in 1189. Its move to Sanuma came four centuries later, after a battle that local people still recount in detail.

In 1591, during the Kasai-Ōsaki Uprising against Toyotomi Hideyoshi, the remnants of the defeated Kasai and Ōsaki clans barricaded themselves inside Sanuma Castle. Date Masamune was ordered to take it. The castle, surrounded by deep marshland, would not fall. According to local tradition, Masamune prayed to the Tsushima deity and a flock of white herons descended on the shallows of the marsh, revealing a crossable line of attack. The castle fell, and Masamune in 1614 ordered his retainer Tsuda Mibu Kageyasu to move the shrine to its present site at the southern edge of Yōkamachi, directly facing the castle. The buildings were deliberately oriented to look north toward Sanuma Castle, making the shrine its guardian — a posture unusual enough that visitors today often notice it before anything else.

The Mikoshi-den shares this orientation. The mikoshi emerges from it each July not toward the south, as one might expect, but toward the castle ground it was once charged with protecting.

What the National Registration Recognizes

The registration of the Tsushima Shrine buildings in March 2024 took in the main hall (1919), the worship hall (1923), and the Mikoshi-den (1928), forming a coherent set of Taishō- and early-Shōwa-period shrine architecture by a single workshop tradition. The main hall is a small ichi-ken-sha nagare-zukuri structure of just 13 square meters, roofed in copper sheeting and densely carved; the worship hall is a much larger 64-square-meter building with an irimoya roof and ornate spandrel carvings. The carpenter who led the work was Ōhata Kōkichi of Sanuma, and the carvings were executed by Kamiyama Torashō (also written Ishii Torashō) of Hakomachi in Sendai.

Registered tangible cultural properties — distinct from "important cultural properties" — are typically buildings over fifty years old that retain architectural quality worth preserving, especially examples of modern craftsmanship that show the technical and artistic standards of their era. The Tsushima Shrine ensemble qualifies on those grounds: it documents how a regional Tōhoku town rebuilt its religious heart after a devastating fire, using the same craftsmen and the same architectural vocabulary over a full decade.

The Mikoshi-den at the Center of the July Festival

For most of the year the Mikoshi-den is closed. The mikoshi sleeps inside, invisible behind the doors. The building's role is custodial: it keeps the shrine's most important ceremonial object dry, dark, and ready.

Once a year, in late July, the doors open. The annual festival is held on the weekend closest to July 24 and 25, with the mikoshi togyo — the procession in which the portable shrine is shouldered through the town — as the centerpiece. Bearers in white robes lift the mikoshi from the hall, parade it through the streets of Sanuma, and return it to the shrine at dusk in the omiya-iri, the homecoming. The return is the moment local residents will tell you to watch for. After hours of walking, the team that carries the mikoshi stages a forceful, swaying re-entry into the shrine grounds, and the building that has stood quietly for the rest of the year suddenly becomes the destination of a town-wide pilgrimage.

Visitors who come outside festival season will not see the mikoshi itself, but the hall is worth pausing at. It sits among the older trees of the precinct — including the great ginkgo on the north side, still bearing burn marks from the 1912 fire — and gives a quieter sense of the shrine than the showy carved main hall provides.

Around the Shrine

Tsushima Shrine is a five-minute walk from the center of Sanuma, the administrative heart of Tome City. A short walk north along the Hasama River leads to the site of Sanuma Castle, now a quiet park with stone foundations and explanatory signage. A further excursion of about thirty minutes by car takes you to Toyoma, the preserved historic district known as Miyagi no Meiji-mura, with its Meiji-era school building, the Mori Butai outdoor noh stage, and the Tome Reminiscence Hall housing arms and armor of the Toyoma Date branch family.

If you have come to Tome in winter, the shrine's Hadaka Mairi — the "naked pilgrimage" held on January 14 each year — is a striking sight. Begun in 1978 as a prayer for recovery after the Miyagi-oki earthquake, it now draws participants from across the prefecture, who walk the snow-cold streets in white loincloths bearing torches.
