The Kamiyama Residence Main House
A low roof of red clay tiles, its eaves dropped almost to head height, marks the Kamiyama family's main house in the Higashisuji settlement on Kuroshima, a flat coral island in Okinawa's Yaeyama group. The single-story timber building went up in 1912, the first year of the Taishō era. It sits at the center of a walled compound and faces south, the orientation that island houses here almost always take. The plan runs seven ken across the front and five ken deep (a ken is the traditional structural bay, close to 1.8 meters), giving a footprint of roughly 139 square meters under a single hipped roof.
Kuroshima lies about a 25 to 30 minute ferry ride south of Ishigaki. Locals call it Heart Island for its shape, and there are several times more cattle here than people. The Kamiyama house belongs to that quiet pastoral landscape: a compact farmhouse on a lane of coral walls and red roofs at the island's center.
Why the house entered the register
In November 2005 the main house was added to Japan's register of Tangible Cultural Properties under registration number 47-0007. Registration is a lighter form of protection than the older designation system. It flags buildings worth keeping and encourages owners to go on living in them, rather than turning them into sealed exhibits. The house was recognized as a regional model of design.
Its hipped roof now carries the red Okinawan tile seen across the Yaeyama islands, but the building began life under thatch, and its deliberately low eaves hold onto that older form. The profile is kept close to the ground for a practical reason: typhoons cross these islands through summer and autumn, and a low, broad-shouldered roof rides out the wind better than a tall one. For anyone reading the history of outer-island houses, this is a legible example of how a Yaeyama farmhouse was built and used.
What to look for
The principal room, called the ichiban-za, is an eight-mat space set with a Buddhist altar and, beside it, a small decorative alcove known as a tokonoma. This pairing sat at the heart of both daily routine and the rites of a Yaeyama household. From the lane you read the building mostly through its silhouette: the long ridge over a modest footprint, the eaves pulled down low, the tile catching afternoon light.
The house does not stand on its own. A coral-stone wall rings the compound, a stone well drops down at the southwest corner, and a small concrete cistern faces the road out front. All three were registered alongside the house, and together they show how one household secured shelter and fresh water on an island where neither was easy to come by. The Kamiyama residence is a private home, so the interior is not open to visitors; the building is best appreciated from the public lane, with the privacy of any residents kept in mind.

Q&A
- When was the main house built?
- In 1912, the first year of the Taishō era. It was originally roofed with thatch and later re-covered with the red clay tile it carries today.
- Can I go inside?
- No. It is a private residence within a living settlement, and the interior is not open to the public. You can take in the exterior from the lane while respecting the residents.
- Why are the eaves set so low?
- The low roofline is an older island form built to withstand the typhoons that pass through the Yaeyama group each year.
- How do I reach Kuroshima?
- Take a ferry from Ishigaki Port, about 25 to 30 minutes. The island is small and flat, so most visitors rent a bicycle and ride into the Higashisuji settlement.
- What is the ichiban-za?
- It is the main reception room of the house, an eight-mat space fitted with a Buddhist altar and a small alcove, where the family's formal and ceremonial life centered.
