Nakano Family Residence North Storehouse

A Storehouse Dated to 1857

Nakano Family Residence Kita-dozō (中野家住宅北土蔵, also written Nakano-ke Jūtaku Kitadozō, the north earthen storehouse) is a two-story dozō-zukuri storehouse in the Harukimachi district of Suzaka City, Nagano Prefecture, built in Ansei 4 (1857) and registered as a Registered Tangible Cultural Property on 25 February 2016.

Of the four Nakano buildings registered that day, this is the only one carrying a precise construction year. The other three are dated to a period rather than a date: mid-Meiji for the shop and the living wing, late Edo for the south storehouse.

1857 places it a decade after the family relocated from Nagano to Suzaka in Kōka 4 (1847), and two years before the port of Yokohama opened to foreign trade and Japanese raw silk began moving abroad in volume. The storehouse went up on the eve of the boom that would remake this town.

It stands at the western end of the northern row of buildings, adjoining the three-story Kurazashiki living wing. The footprint is small, 31 square meters, under a tiled roof.

Why It Was Registered

The registration criterion is contribution to the historic character of the national landscape, and in this case the phrase is close to literal. Suzaka is known for the number of its storehouses. Walk the old center and the same white-and-grey walls repeat down street after street, a rhythm produced by generations of merchant families each building their own kura.

The Kita-dozō belongs to that fabric. It is not a showpiece. What gives it value is that it survives intact within a compound where every other element also survives, so the relationship between shop, residence and storage can still be read on the ground.

Its 1857 date also makes it a physical marker of when the Nakano household had established itself sufficiently to invest in fireproof storage. Building a dozō was expensive. Layer upon layer of earth had to be applied over a timber frame and left to dry between coats, a process that could take a year or more.

What to Look For

The most instructive detail is invisible from outside, and it concerns doors. The ground floor has its entrance on the south side, opening to the yard. The second floor has a separate entrance on the east, reached directly from the Kurazashiki. Two floors, two doors, two routes that never cross.

That arrangement solved a practical problem. The ground floor originally held everyday goods, things fetched and returned constantly, while the upper floor held household furnishings and possessions brought out only for seasons or occasions. Separating the circulation meant routine traffic never disturbed the storage above.

Outside, look at the junction between the wall and the roof. This is an okiyane, literally a placed roof: an independent timber roof structure set over the earthen vault rather than built into it. The plastered box beneath is the fire barrier; the roof above is a rain cover that can be repaired or replaced without cutting into the sealed shell. Where the two meet you can often see a shadow gap. It is the standard storehouse form in this district.

The Kita-dozō is private property, still in use, and is not open to visitors. Nothing of the interior can be seen. Even the exterior is only partly visible, since the building sits deep in the compound behind the shop, and the best available view is down the stone-paved lane that runs west between the two shop buildings. Travellers wanting to understand the type at close range should visit Mayugura, a three-story cocoon warehouse a short walk away that is open to the public.
