A Grain Store on the Silver Mine Highway
The Furukawa Family Granary (古川家住宅穀蔵, Furukawa-ke Jūtaku Kokugura, also written Furukawa-ke Jutaku Kokugura) is a two-storey earthen-walled storehouse completed in 1917 at 370 Yanagiwaramachi 1-chome in Aizuwakamatsu City, Fukushima Prefecture, and it was entered on Japan's national register of Tangible Cultural Properties, buildings section, on 13 March 2025.
The road out front explains the building better than any label could. Aizu's Ginzan Kaidō, the Silver Mine Highway, starts at Ōmachi Yotsukado in the centre of Aizuwakamatsu and runs about 72 kilometres southwest to Kobayashi in Tadami Town, cutting across the Aizu basin and into the steep Oku-Aizu valleys before continuing over the passes toward Niigata. Silver from the Karuizawa mine at Yanaizu travelled this way from the late sixteenth century until the mine faded in the middle Meiji years. Salt and ramie fibre came and went along the same route, and the Tokugawa shogunate sent its provincial inspectors down it nine times.
Rice moved along it as well. The Furukawa household dealt in grain, and this is the building where the stock was kept.
The structure covers 77 square metres. Repairs in 1955 and again in 1987 are recorded in the national database, which is a large part of why a working store of the Taishō era is still standing on its original plot rather than surviving only in photographs.
What the Registration Recognises
Japan created the registration system in 1996 as a lighter alternative to designation. Buildings of roughly fifty years or older can be registered when they deserve conservation but do not require the strict controls that come with status as an Important Cultural Property. Owners keep using the building; in exchange they accept notification duties for major alterations and receive technical guidance and certain tax relief. Three criteria exist, and a property needs to satisfy only one.
The granary qualified under the first of them, the criterion for structures that contribute to the historic character of the national landscape. Its registration number is 07-0287, granted in the 109th round of registrations. The neighbouring zashiki-gura, registered on the same day, came in under a different criterion, which is a useful hint that the two buildings were valued for different reasons.
Landscape, in this context, means something specific. A plastered gable end facing an old highway, with the shape and rhythm of storehouse doorways that a passer-by in 1920 would have recognised at a glance, does work that no reproduction can do. Aizuwakamatsu lost a great deal of its pre-war fabric, first in the fighting of 1868 and then through the ordinary attrition of the twentieth century. Buildings that hold the line of a historic road are scarcer here than the city's reputation might suggest.
Looking at the Building
The granary is a dozō, an earthen-walled store, of two storeys under a gabled pantile roof. It is hirairi, meaning the entrance sits on the long eaves side rather than under the gable. Lime plaster covers the walls and is carried all the way up to the eaves, sealing the timber frame inside a fireproof shell. The lower skirt of the wall is finished in mortar, a modern material for 1917 and a practical answer to splashing rain and snow piled against the base through an Aizu winter.
The doors are the detail worth crossing the street for. Openings at the doorway and windows carry kakego-nuri fittings: leaves and frames cut with interlocking stepped rebates, then plastered over, so that when the door swings shut the joint closes in a series of overlapping steps instead of a single straight gap. Smoke and embers cannot find a path through. Making them takes a plasterer willing to build up and cut back many thin coats, and the result reads from the road as unusual depth and weight around every opening.
Inside, the ground floor is divided. The northern portion is a doma, a beaten earth floor, and this was the rice store. The southern portion is raised and boarded. Upstairs was the grain store proper, and here the roof frame is left in plain view: a tsukadate wagoya, the Japanese roof type in which short vertical struts stand on the tie beams to carry the purlins above. No ceiling hides it. Anyone who has looked up inside a Japanese storehouse and seen a forest of squared timber will know the effect, though this one is worth studying for how little decoration it carries. Every member is there to hold up the roof.
Compare that upper frame with the roof over the zashiki-gura a few paces southeast, where a Western king-post truss was chosen instead. One household, two buildings a year apart, two different structural ideas. The Taishō period was like that.

Q&A
- Can the Furukawa Family Granary be visited, and does it have opening hours?
- The granary is private property and does not operate as a museum, so there are no published opening hours or admission charges. Reporting at the time of the 2024 recommendation stated that the granary and the adjacent zashiki-gura were being used for exhibitions and occasional events, which suggests the interior opens from time to time rather than on a fixed schedule. Anyone hoping to see inside should ask the Aizuwakamatsu tourist information office or the city's cultural properties section in advance. The exterior stands directly on the street and can be looked at from the public road at any hour.
- Where exactly is the Furukawa Family Granary, and how do I reach it?
- The address is 370 Yanagiwaramachi 1-chome, Aizuwakamatsu City, on the southwest side of the city centre. The closest railway station is Nishi-Wakamatsu, served by the JR Tadami Line and the Aizu Railway, roughly one kilometre away and about fifteen minutes on foot. Nanukamachi Station lies a little further north, about twenty minutes' walk. Drivers should note that this is a residential street with no visitor parking; the paid car parks around the city centre are the sensible option.
- What makes the Furukawa Family Granary different from an ordinary storehouse?
- Scale and specialisation. Many merchant houses kept a small kura for valuables and household goods. This one was built to hold commercial quantities of rice, with an earth-floored storage bay on the ground floor and a second storey given over entirely to grain. The kakego-nuri doors on every opening, the plaster carried up to the eaves and the mortar skirt all point the same way: a building designed to keep fire, damp and vermin away from stock that represented the family's capital.
- Is photography permitted at the Furukawa Family Granary?
- Photographing the exterior from the public road raises no issue, and the plastered gable and doorways repay a careful look in raking morning or late afternoon light. Interior photography would depend entirely on the owner's permission and on the terms of whatever exhibition happens to be running. Since this is a family's property rather than a public facility, keeping off the plot and out of the entrance is the basic courtesy.
- What else can I see near the Furukawa Family Granary?
- The Nanukamachi district, about fifteen minutes north on foot, keeps a run of Meiji and early Shōwa shopfronts, storehouses and Western-style buildings along a single street, and several of them are registered properties in their own right. Tsuruga Castle sits east of the granary within a comfortable walk. Following the Ginzan Kaidō back toward Ōmachi Yotsukado, the highway's starting point, gives the granary its context better than any single monument does.
