A Brick Storehouse Built for a Festival Float
A small brick building occupies a street corner in Miya-chō, a coastal district of Gamagōri in Aichi Prefecture. It measures only about 5.9 meters on each side, yet the arched doorway on its front rises close to six meters. That unusual proportion gives away the building's single purpose. This is a yamagura, a storehouse for a festival float, and the height was needed to roll the float in and out.
Completed in 1921, the Miyachō Kita-ku Float Storehouse holds the Sangaigasa, the tall float that the town's North district hauls through the streets and into the sea each autumn during the Miya Festival. In October 2007 the building was added to Japan's register of Tangible Cultural Properties.
Float storehouses are common across festival towns in Japan, but they are almost always built of timber or finished as plaster-walled dozō. A brick one is the exception, which is much of the reason this modest structure earned national recognition.
Registered, Not Designated: Why the Distinction Matters
Japan protects its cultural properties through two separate systems. The older one, dating to the late nineteenth century, designates objects and buildings as Important Cultural Properties or National Treasures after rigorous review. The newer one, introduced in 1996, simply registers them. Registration carries a lighter regulatory touch and was created to encourage owners to preserve the many modern buildings, roughly fifty years old or more, that fall outside the stricter designation tiers. The float storehouse belongs to this registered category, listed under the criterion that it would be difficult to recreate.
The case for preserving it rests on its material and its timing. The walls are laid in header bond, with only the short ends of the bricks showing on the surface, set on a stone base that rises about 1.4 meters from the ground. A copper cornice runs along the wall, the lower section is faced in stone, and the gabled roof is covered in pantiles. Those last features belong to the vocabulary of the traditional plaster storehouse; the brick body and the arched entrance do not.
Timing sharpens the point. Brick storehouses spread through Japan from the late Meiji era, but the Great Kantō Earthquake of September 1923 destroyed brick buildings on a vast scale, and construction in the material largely stopped afterward. Finished in 1921, this storehouse stands near the close of that brief brick-building period. The national database describes it as a rare surviving example of a brick float storehouse; prefectural records go further and call it the only one left in Japan.
The Float Inside and the Festival It Serves
The Sangaigasa float was built in the same year as its storehouse, 1921, under the master carpenter Hanada Yoshichika of Ushikubo, in what is now Toyokawa. Its components were made at Kōshō-ji temple and assembled in front of the new storehouse. The float reaches about 5.4 meters in height, which explains the towering doorway behind which it waits out the year.
The festival itself goes back to 1696. According to local tradition, the village headman dreamed that the deity of Yatsurugi Shrine processed to Wakamiya Shrine, and the townspeople reenacted the journey as a rite. Today six districts take part, four of them with floats, parading between the two shrines over two October days.
The climax is the kaichū-togyo, the sea procession. Crews of roughly two hundred men, stripped to loincloths and sashes, drag each float about 300 meters through the surf off Miya Onsen. The floats are engineered for this: their steering bars are fixed crosswise to ease the push through water and guard against tipping, and their wheels are wide cross-cut pine rollers that move smoothly over wet sand. The sea procession lapsed in 1960 after coastal land was reclaimed, then returned in 1996 for the festival's tricentennial. Gamagōri designated the North district's float a municipal folk cultural property back in 1957.
Seeing the Storehouse and What Lies Nearby
The storehouse is working property owned by the North district, not a museum, so there is no interior tour. Its street-facing front is easy to see year-round, a short walk from Yatsurugi Shrine. The building reads as a sealed brick box for most of the year; the moment it matters is mid-October, when the great doors swing open and the Sangaigasa rolls out.
That festival weekend is the reason to time a visit. Yatsurugi Shrine and Wakamiya Shrine anchor the two ends of the parade route, and the beach in front of Miya Onsen hosts the sea procession. Miya Onsen itself, a coastal hot-spring resort, makes a natural base, and Gamagōri is known regionally for its seafood. Visitors outside festival season can still walk the route, view the exterior, and pair it with the shrines and the shore.

Q&A
- Can I go inside the storehouse?
- No. It is working storage owned by the local district, not an exhibition space, so there is no public access to the interior. You can view the brick exterior and its tall arched doorway from the street, near Yatsurugi Shrine.
- When is the best time to see it in use?
- During the Miya Festival in mid-October, usually the third or fourth weekend depending on the tides. The float is rolled out and paraded over two days, and the sea procession takes place on the second day.
- Why is this building considered important?
- A float storehouse built of brick is very unusual, since most are timber or plaster. This one is often cited as the only surviving brick float storehouse in Japan, and it dates to 1921, near the end of the country's short brick-building era.
- Why is the doorway so tall for such a small building?
- The Sangaigasa float stored inside stands about 5.4 meters high. The arched opening rises to roughly 5.9 meters so the float can pass through it.
- How do I reach the area?
- The storehouse sits in Miya-chō, Gamagōri, near Yatsurugi Shrine. Gamagōri is reachable by train from Nagoya. During the festival, roads in the area are closed to traffic, so public transport is strongly recommended.
