The Oldest House Standing in Ōita City
Gotō-ke Jūtaku (後藤家住宅, also written Goto-ke Jutaku), the Gotō family house at Niogi in Ōita City, Ōita Prefecture, is a thatched Edo period farmhouse designated an Important Cultural Property on 23 June 1975. It measures 14.0 metres along the front and 7.7 metres in depth, under a hipped roof of thatch.
The national register still carries the property under its old address, Nozuharu-machi in Ōita District, a town that merged into Ōita City in 2005. Anyone searching for the house will find both names in circulation.
The Gotō family served as shōya, the headman who collected the rice tax, settled disputes and stood between the village and the domain administration. This building was their main dwelling. Ōita City calls it the oldest surviving house in the municipality, and it has passed the two-and-a-half-century mark.
Its plan is what specialists call a sugoya (直屋, also written 直家), a house whose footprint is a plain rectangle. The alternative in much of Japan was the magariya, an L-shaped house with a wing bent out at one end, usually to stable horses. Ōita Prefecture favoured the straight plan, and this is the type example.
The house faces west. Walking in from that side, the sequence runs earth floor, board room, main room, formal room: doma with its cooking range, then the ita-no-ma, then the hiroma with a sunken hearth, then the zashiki. Behind the hiroma sit two small chambers the family called naisho. Behind the zashiki is a nando, the closed storeroom that also served as a sleeping space.
Why the Agency for Cultural Affairs Designated It
The designation record gives a compact reason: the plan and structural form carry the characteristics of this region, and the house is a good example of early date. Both halves of that sentence do work.
Dating is the looser half. The Agency for Cultural Affairs places construction in the later Edo period, between 1751 and 1829. Ōita City puts it around the middle of the eighteenth century. The city tourism association says the second half of that century. The prefecture's own archive describes it as mid-Edo. No inscribed ridge tag or dated document has settled the question, so the figures come from reading the carpentry, and readers should treat any single year with caution.
The structural evidence is firmer. Above the doma the roof is carried on a double-beam arrangement, one tier of beams stacked over another. Long timbers called sashimono run through the frame, and where a post meets one of these members the two are cut half away and lapped together, a joint known as aigaki. Ōita Prefecture's record notes that the frame was assembled without iron nails, relying on cut joints alone, and that posts and the deep lintels called sashi-kamoi were finished with a chōna, the Japanese adze, everywhere except around the formal room. An adzed surface is not flat. It carries shallow scallops that catch light along their edges, and it belongs to a period before the plane became standard for finishing structural timber.
Designation was followed by a full campaign of repair. The house was taken apart beginning in late April 1977 and reassembled by 1978, which is why the interior reads so clearly today. A further round of maintenance ran into the summer of 2023.
What to Look for, and How to Visit
Three details repay attention.
The first is the shitomido hung across the front of the hiroma. A shitomido is a shutter whose upper half swings up and hooks to the ceiling, leaving the lower half in place. The type is familiar from aristocratic architecture of the Heian and Kamakura periods and became unusual in later farmhouses, so its survival here points to the age of the building. The zashiki front takes a different treatment, a latticed window.
The second is the zashiki ceiling, laid as ajiro: thin strips of wood or bamboo woven into a diagonal plait. It is the one place in the house where the carpentry turns decorative, and it marks the room out as the space where guests were received.
The third is the roof itself. Thatch keeps a house cool through the humid Kyushu summer and warm in winter, and it is the single most demanding part of the building to maintain. Re-thatching Gotō-ke Jūtaku is said to have taken around 300 da of reed, a da being the load of six bundles carried by one ox. Work on that scale was done collectively by the village.
Visiting requires some care. The house is open to the public and there is no admission charge, but it is a private residence, and Ōita City asks that visitors behave accordingly. Opening times are not fixed, so calling the Nozuharu Branch Office of Ōita City on 097-588-1111 before setting out is the sensible course, particularly since repair work has closed the house in the past. Photography of the exterior from the approach is unproblematic; ask before photographing indoors.
Getting there needs a car. Niogi lies in the hills of the old Nozuharu district, about sixty minutes from JR Ōita Station and around thirty-five minutes from the Ōita interchange. The prefecture's archive describes the thatched roof rising in the winter sun with the ridge of Yoroigatake across the valley, and that is roughly what a visitor finds. The Michi-no-Eki Notsuharu roadside station, the Nanase Dam and the prefectural forest park all lie within a short drive, which makes the house easy to fold into a day in the uplands rather than a trip on its own.

Q&A
- Is Gotō-ke Jūtaku open to visitors, and is there an admission fee?
- It is open and admission is free, but the building is a private residence and hours are not published. Contact the Nozuharu Branch Office of Ōita City on 097-588-1111 in advance. The house has closed for repair work in the past, so confirming before you travel is worthwhile.
- When was Gotō-ke Jūtaku built?
- Sources differ. The Agency for Cultural Affairs gives the later Edo period, 1751 to 1829. Ōita City says around the middle of the eighteenth century, and the city tourism association says the second half. No dated inscription has been found, so the estimates rest on structural analysis.
- What does it mean that Gotō-ke Jūtaku is a sugoya?
- A sugoya is a house whose plan is a simple rectangle, as opposed to a magariya with an L-shaped wing. The straight plan is the representative farmhouse form of Ōita Prefecture, and this building is cited as its leading surviving example.
- How do I reach Gotō-ke Jūtaku from Ōita Station?
- By car, roughly sixty minutes from JR Ōita Station or about thirty-five minutes from the Ōita interchange. The house stands in the hills of the former Nozuharu town at Niogi 1161, and public transport to the site is limited.
- What is the most distinctive feature inside Gotō-ke Jūtaku?
- The shitomido across the front of the main room, an upward-hinged shutter rarely retained in farmhouses of this type, together with the woven ajiro ceiling in the formal room and the adze-finished posts and lintels through the rest of the house.
