Fukuda Residence Stone Wall and Earthen Wall: A Castle-Like Rampart in a Mountain Hamlet
Deep in the mountains of southern Wakayama, in the hamlet of Sebon-Higashikurigaito in the town of Susami, a stone wall four metres high runs for ninety-eight metres across the front of a private estate. It is laid in nuno-zumi, regular horizontal courses, and given a gentle inward curve, the sori, of the kind that fortress walls use to shed weight and resist collapse. The masonry is exact, and the overall effect is unmistakably that of a castle. This is the Fukuda Residence, and its great walls are what carry its national listing.
The property in fact holds two long stone walls and an earthen wall. The front rampart accounts for the ninety-eight metres; a second stone wall, fifty-six metres long and laid in the same coursed technique, closes the rear of the site, bringing the stonework to a total of about 154 metres, fitted with stone steps. Along the front, a plastered earthen wall, the dobei, extends a further sixty-three metres beneath its own ribbed-tile roof. The stonework belongs to the late Edo period, with additions recorded in 1900 and 1914.
Who Built the Walls
Walls of this precision did not come from casual labour. By local account, they were very likely the work of the kurokuwa-shū, a guild of skilled stonemasons who lived in the district and built across the surrounding country. The attribution is reported locally rather than fixed by document, so it is best held as a strong likelihood rather than a certainty. Either way, the quality is plain: a remote farming household commanded craftsmanship usually associated with domain castles and temple precincts.
The Fukuda estate sits along the old Koza Kaidō, the inland route that crossed the rugged Kii Peninsula toward the southern coast. The house itself was raised in 1901 with a detached reception room added in 1903, and the walls frame this Meiji-era farmstead. Together they show how a leading family of a mountain village expressed its standing not through a grand house alone but through the engineered ground it stood on.
Why It Is Registered, and How to See It
The stone and earthen walls were registered as a Registered Tangible Cultural Property on 23 February 2012. This category, set up in 1996, protects buildings and structures that shape a historic landscape, a tier below the Important Cultural Property and National Treasure designations. Here the listing recognises the walls as a single composed work: the long ramparts and the plastered earthen wall give an ordinary hillside the bearing of a fortified compound.
The Fukuda Residence is a private home and is not normally open to visitors; the interior is reached only on rare guided occasions. The walls, however, line the public approach and can be appreciated from outside. Before or after a visit, the Susami Town Museum of History and Folklore holds material on the residence, and the town's coast, with its seaside aquarium and the cliffs of the Kareki-nada shore, makes a natural pairing for a day in the area.

Q&A
- How big are the walls?

- Who built them?
- They are very likely the work of the kurokuwa-shū, a local guild of stonemasons. This is reported locally rather than documented, so it is best treated as a strong likelihood.
- Why do they look like castle walls?
- They use coursed masonry (nuno-zumi) with a gently curved batter (sori), the same techniques fortress walls use for stability, which gives the estate its fortified appearance.
