A Storehouse Made of Concrete, Dressed as Plaster
The Treasury of Akumi Kanbe Shinmeisha (安久美神戸神明社神庫, also written Akumi-Kanbe Shinmeisha) is a reinforced concrete storehouse in Hatchodori, Toyohashi City, Aichi Prefecture, built in 1930 and registered as a National Registered Tangible Cultural Property on 10 September 2010. It measures about 5.5 metres along the front and 4.5 metres deep, covering roughly 30 square metres, and stands to the south-east of the Worship Hall, facing the Kagura Hall across the open ground.
From twenty paces it looks like a dozo, the thick-walled plastered storehouse of any Japanese merchant town. It is not. Under the render is reinforced concrete, chosen in 1930 because a shrine's treasures burn.
That decision produced the most quietly interesting building in the precinct. Everything around it is timber, built in the same campaign by the same patrons; this one alone was given a modern structural system, and then asked to keep the appearance of the tradition it had replaced.
How the Translation Was Made
The Agency for Cultural Affairs describes the Treasury as a storehouse expressing the traditional dozo form in reinforced concrete. Two details carry that expression.
The first is the eaves. A plastered storehouse gets its character from the slight upward curve of the eave line and from the sumigi, the corner rafters that run out diagonally at each hip. Both were reproduced here in a material that has no reason to curve at all. Concrete is cast into whatever shape the formwork dictates, so the curve is a decision rather than a consequence.
The second is the interior. Aichi Prefecture's survey records that the inside shows pillar forms and corner rafters as visible elements, with the ceiling shaped to follow the hipped roof above. The room measures about 4.5 metres by 5.4 metres and is divided into two bays in each direction, giving a dense grid of supports and an unusually solid construction. A concrete box could have been left flat and blank inside. It was not.
At the front, a dobisashi canopy shelters the entrance across a span of about nine shaku, roughly 2.7 metres, carried on posts. The roof is hipped and tiled in sangawara pantiles, matching the Kagura Hall opposite rather than the copper of the Main Hall.
Registration came under the criterion for contribution to the historic landscape. The Treasury was not held up as a design model in the way the Main Hall was. Its value lies in holding its corner of the precinct, in a form that keeps the visual agreement with its timber neighbours while doing a job none of them could do.
What a Shrine Treasury Holds, and How to See It
A shinko stores the sacred objects and ritual implements a shrine cannot afford to lose. At Akumi Kanbe Shinmeisha the accumulated holdings reach back a long way. Shrine records describe the Imagawa, who governed Mikawa Province, as devoted patrons who rebuilt the halls and presented land, swords and the masks used in the shrine's rites. In 1505 Imagawa Ujichika had Makino Kohaku raise Imahashi Castle, later called Yoshida Castle, and the shrine was rebuilt within the walls as guardian of the castle's north-eastern approach.
Masks matter here more than at most shrines. The Onimatsuri, designated an Important Intangible Folk Cultural Property on 28 January 1980, turns on the confrontation of a red demon and a tengu, with a blue demon and other roles filled by parishioners across two days each February. Fire in a wooden storehouse would end a line of transmission, not merely destroy property. Seen that way, the reinforced concrete is a form of custodianship.
The building's interior is closed, as a treasury's would be. The exterior can be examined freely from the precinct, which is open without charge and without fixed hours. Stand between the Treasury and the Kagura Hall and the pairing becomes clear: two tiled roofs of similar bulk facing one another across the space in front of the Worship Hall, one of timber and one of concrete.
The shrine office beside the approach handles prayers, amulets and seal stamps daily between 9:00 and 16:00, and can be reached on 0532-52-5257. No general notice restricts photography of the buildings; during rites, ask at the office.
Reaching the shrine takes about ten minutes from Toyohashi Station. The streetcar leaves from outside the east exit; alight at Shiyakusho-mae or Toyohashi-koen-mae after roughly seven minutes and walk three, at a flat 200 yen. By car, the shrine is on National Route 1 immediately east of the Toyohashi police station, and there is parking on site.

Q&A
- Why is the Treasury of Akumi Kanbe Shinmeisha built of reinforced concrete?
- For fire resistance. Aichi Prefecture's survey records it as a fireproof building, and reinforced concrete was chosen in 1930 to protect the shrine's sacred objects and ritual implements. The other four registered buildings at the shrine are all of timber.
- Does the Treasury of Akumi Kanbe Shinmeisha look like a modern building?
- No. Its exterior imitates a traditional plastered dozo storehouse, with a curved eave line and exposed corner rafters at each hip, under a hipped tiled roof. The concrete structure is not visible from outside.
- Can visitors go inside the Treasury of Akumi Kanbe Shinmeisha?
- No. It is a storehouse for sacred objects and is closed. The exterior may be viewed at any time from the precinct, which is open without charge.
- Where does the Treasury of Akumi Kanbe Shinmeisha stand in relation to the other buildings?
- South-east of the Worship Hall, directly opposite the Kagura Hall, which stands on the south-west side. The two face each other across the ground in front of the Worship Hall where the Onimatsuri takes place.
- Under which criterion was the Treasury of Akumi Kanbe Shinmeisha registered?
- Contribution to the historic landscape, the same criterion applied to the Kagura Hall and the Purification Pavilion. The Main Hall and the Offering and Worship Halls were registered instead under the criterion for design that sets a standard.
