A Storehouse Standing on Its Own Retaining Wall
Sakashita Tsutomu-ke Jutaku Dozo oyobi Ishigaki (坂下勤家住宅土蔵及び石垣, in full Hepburn Sakashita Tsutomu-ke Jūtaku Dozō oyobi Ishigaki), the earthen-walled storehouse and stone wall of the Sakashita family residence at Umaki in Shodoshima-cho, Kagawa Prefecture, was built in 1908 and entered Japan's national register of Tangible Cultural Properties on 2 March 2006.
The registration treats building and wall as one property, and the reason becomes obvious on the ground. A stone wall runs about twenty metres, coming along the southern edge of the plot and turning up the western side. The storehouse sits at the southwest corner of the residence, and its west wall rests directly on the top of that stonework. Take the wall away and the building has nothing to stand on.
The storehouse itself is small: two and a half ken by two, a footprint of roughly 4.5 by 3.6 metres, giving a registered building area of 20 square metres. It rises two full storeys under a gabled roof laid in hongawara, the heavy tiling of flat pans and semi-cylindrical covers. A short canopy projects at the centre of the east face to shelter the doorway.
Dozo is the term for a Japanese storehouse built up in thick layers of earth over a timber frame, then finished in plaster. The mass of earth resists fire and holds temperature steady, which is why farming and merchant families kept their documents, seed grain, ceremonial goods and tools inside one. The upper portion of the outer wall here is finished in white shikkui lime plaster.
The Criterion of Work That Cannot Be Casually Repeated
Three criteria govern entry to the national register of Tangible Cultural Properties. A building may qualify because it contributes to the historic landscape of the country, because it serves as a model of its type, or because it would not be easy to reproduce. The main house and the barn on this property came in under the first. The storehouse and its wall came in under the third.
That difference is worth sitting with. The Agency for Cultural Affairs is saying that the fabric here embodies craft skills which cannot simply be commissioned again. Two trades meet on this corner of the plot: the stonemason who laid twenty metres of wall on a sloping site so that a two-storey earthen building could sit on its crest, and the plasterer who finished the shell above.
The record points specifically at the second-floor window on the south gable. The plasterwork around that opening is described as elaborate, which in the vocabulary of sakan, the Japanese plastering trade, means the surround has been modelled up in relief rather than run flat. Openings are the weak point of an earthen storehouse; the plasterer builds them out into thickened frames, and the building's few decorative gestures collect there.
Registration number 37-0302 was announced in the forty-ninth round, gazetted on 23 March 2006, three weeks after the register entry itself.
Stone, and an Island Made of It
Shodoshima has a long relationship with cut stone. Granite quarried on the island and its neighbours went into the rebuilding of Osaka Castle in the early seventeenth century, and blocks that never left survive at quarry sites along the coast. The Agency for Cultural Affairs recognises that history in the Japan Heritage story of the stone islands of the Seto Inland Sea, in which Shodoshima-cho is a participating municipality. Stone walling on this scale, holding up a hillside plot, belongs to that working tradition rather than to any grand project.
The gable carrying the ornamented window faces south, the same direction as the road along the lower edge of the site, so the most worked face of the building is the one turned toward passers-by. The white plaster of the upper wall against the dark hongawara ridge reads clearly even at a distance.
Umaki lies within Hishio no Sato, the soy-sauce district on the island's south coast, and most of the registered architecture nearby belongs to brewing families. This corner belongs to a farm. The scale of the storehouse, twenty square metres, says something about that: a household of middling means, storing what one family needed to keep dry and safe.
The property is a private residence and no public opening has been announced. The Agency's record leaves the owner field blank and describes no arrangement for entry. The wall and the south gable can be seen from the public road. Visitors should stay on it.
Reaching Umaki means a ferry to Kusakabe out of Takamatsu or to Sakate out of Kobe, then the Shodoshima Olive Bus Sakate Line to the Umaki stop, with island fares capped at 300 yen.

Q&A
- What is Sakashita Tsutomu-ke Jutaku Dozo oyobi Ishigaki?
- It is the earthen storehouse and stone retaining wall at the Sakashita family residence in Umaki, Shodoshima-cho, Kagawa Prefecture, built in 1908 and registered as a Tangible Cultural Property on 2 March 2006 under number 37-0302. The two elements are registered together because the storehouse rests on the wall.
- Why were the storehouse and the stone wall of the Sakashita residence registered under a different criterion from the other buildings?
- They qualified as work that would not be easy to reproduce, while the main house and barn qualified as contributing to the historic landscape. The distinction points at the stonemasonry and the modelled plasterwork, both of which depend on trade skills that have become scarce.
- How large is the storehouse at the Sakashita residence?
- It measures two and a half ken by two ken, a registered building area of 20 square metres, and stands two storeys high under a gabled hongawara roof. The accompanying stone wall runs about twenty metres.
- Can visitors enter Sakashita Tsutomu-ke Jutaku Dozo oyobi Ishigaki?
- No. The site is a private residence and no public opening has been announced. The stone wall and the south gable of the storehouse can be seen from the public road, and photography from the road is unproblematic.
- What should I look at on the storehouse of the Sakashita residence?
- The window surround on the south gable at second-floor level, which the national record singles out for its plasterwork, and the line where the white lime-plastered wall meets the top of the stone wall on the west side.
