Sato Family Residence Kanjōbeya: A Rice Bin, an Earth Floor, and the Room Where Accounts Were Settled
Built into the south wall of this building is a komebitsu, a rice bin. Not furniture that could be carried out, but joinery fixed to the fabric of the room. Everything else about the Kanjōbeya follows from that fact.
Kanjō means accounts, reckoning, settlement. The Kanjōbeya is the room where the Sato household did business, and in rural Nagano before the cash economy took hold, business meant rice. Tenants delivered it, labourers received it, obligations were discharged in it. A room where accounts were settled needed somewhere to put the rice, and it needed a floor you could walk onto in muddy boots without apology.
So the floor is doma, packed earth, level with the ground rather than raised on joists. There is no tatami, no threshold to step over, no ceiling. The roof framing is left exposed overhead, the way it is in a workshop rather than a parlour. This is a single-storey timber building of roughly 25 square metres, dated by the Agency for Cultural Affairs to the Meiji era, between 1868 and 1912, and registered as a Tangible Cultural Property of Japan on 28 October 2011 under number 20-0398.
A Roof With No Ends
The Kanjōbeya stands on the stone retaining wall along the road, wedged between the Tomobeya on one side and the Higashi-dozō storehouse on the other. Its roof records that position.
The roof form is ryōsage-zukuri, sometimes rendered as a "both-sides-sloping" roof. Two slopes fall from the ridge, as in an ordinary gabled roof, but there are no gable walls at either end because there is no space for them; the building runs up against its neighbours. The tiling is sangawara pantile, the standard roofing of the region.
It is a modest technical point that turns out to be a historical one. The roof form is only possible if the neighbouring buildings were already there or were planned alongside it. The Higashi-dozō is late Edo, a generation or more older. The Kanjōbeya was fitted into a gap that the storehouse had already defined.
Closed to the Road, Open to the House
The two long walls of the Kanjōbeya are treated as opposites, and the logic is easy to read once you know what to look for.
Facing the road: koshi-shitami itabari, horizontal boarding along the lower wall, and above it a yokogōshi window, a lattice of horizontal bars set into the wall. Above that, lime plaster in shinkabe construction with the posts left visible. The horizontal lattice lets light and air in while keeping passers-by from looking through. A room holding the household's rice and its ledgers was not going to open itself to the street.
Facing the main house: almost nothing. A short sodekabe, a wing wall, toward the north end, and otherwise the side is left open. The Kanjōbeya faces the yard the way a counter faces a shop floor.
That asymmetry is the building's argument. One wall performs for the street; the other works.
Registration, and What You Can See
Japan's registration system for buildings dates to 1996 and was created for structures that would never be designated Important Cultural Properties but were disappearing all the same. It is deliberately light: owners notify the government before significant exterior alterations and are otherwise free to use the building. Roughly speaking, it protects the outside so the inside can carry on living.
The Kanjōbeya was registered under the criterion for structures contributing to the historic landscape of the nation, and the official record situates it explicitly as the middle term between its two neighbours. The three together, the description says, form a continuous run with a substantial presence along the road.
The Sato property is a private home. The national database lists no owner name and no managing body, and there is no visitor programme or interior access. The view from the public road is available, and since streetscape is what the registration assessed, it is also the right view. Stay on the roadway and respect the household's privacy.
Visitors wanting comparable buildings they can enter will find them elsewhere in Saku City. The former Nakagomi School, an Important Cultural Property and Historic Site, is open to the public. The Takeshige Honke Brewery and Takeshige Family Residence in Motai preserves more than thirty registered structures along a former Nakasendō streetscape and continues to brew sake; confirm arrangements before you go.

Q&A
- What is a Kanjōbeya?
- Kanjō means accounts or settlement, so the name indicates a room used for the household's business dealings. The built-in rice bin and earthen floor are consistent with that use.
- Why does the roof have no gable ends?
- The building sits between the Tomobeya and the Higashi-dozō, so the roof takes the ryōsage-zukuri form: two slopes from the ridge with no gable walls, because the ends meet the adjoining buildings.
- Can the interior be visited?
- No. This is part of a private residence with no public access. The exterior may be viewed from the public road.
- What is doma?
- A floor of packed earth at ground level, used in Japanese houses for work areas, cooking, and passage. It requires no shoe removal, which suited a room where people came and went with goods.
- How does registration differ from Important Cultural Property designation?
- Registration, introduced in 1996, mainly requires notification before major exterior changes and offers tax relief and repair advice. Designation as an Important Cultural Property is far stricter, requiring permission for alterations, and applies to a much smaller group of buildings.
