A Dated Farmhouse in the Chikushi Mountains

The Yoshimura Residence (吉村家住宅, Yoshimura-ke Jūtaku), registered nationally as Yoshimura-ke Jūtaku, Fuji-chō, Saga-gun, Saga Prefecture, is a thatched farmhouse at Kamimutsuro in the Fuji-chō district of Saga City, Saga Prefecture, built in Tenmei 9 (1789) and designated an Important Cultural Property on 5 February 1974.

Kamimutsuro is not on the way to anywhere. The hamlet sits in the middle of the Chikushi mountain range, close to the Fukuoka prefectural border, in a valley where the flat ground runs out quickly and forestry rather than rice has long carried the local economy. The house faces south, one long unbroken ridge under thatch.

That unbroken ridge is the point. Farmhouses across much of Kyushu were built in the magariya manner, with the plan bent into an L. In the mountains of northern Saga the preferred form was the suguya, sometimes read sugoya and written 直家 or 直屋, in which the whole house sits under a single straight ridge. The Agency for Cultural Affairs describes the Yoshimura Residence as a representative example of the type and notes that it is large for a house of its date in the district.

The national register gives the structure as 15.1 metres along the ridge and 8.4 metres across, hipped roof, thatched, with a lean-to at the rear covered in pantiles. Saga Prefecture's heritage archive gives the traditional bay count instead: eight ken by five ken, which it converts to roughly 14.4 by 9 metres. The two sets of figures describe the same building measured by different conventions, and the national figures are the ones to cite.

A Date Written in Ink on a Beam

Most surviving farmhouses cannot be dated precisely. Carpenters did not sign their work, families rebuilt piecemeal, and the usual method is to compare joinery details against houses whose dates are known. The Yoshimura Residence escapes this problem, which is the reason it carries a national designation rather than a local one.

During alteration work, an ink inscription came to light on the jointed section of the side purlin in the northwest corner room. It recorded the year Tenmei 9 (1789) and the name of a carpenter. Sources differ on which village that carpenter came from: Saga Prefecture's archive reads the inscription as naming Ochiai village, while a private architectural survey transcribes a different place name. The Agency for Cultural Affairs summary avoids the question and states simply that a local carpenter built the house in Tenmei 9. The year itself is not in dispute.

What that single line delivers is a fixed point. Saga Prefecture has older houses, but none whose construction year can be demonstrated. The Yoshimura Residence is the earliest dwelling in the prefecture with a secure date, and every other undated farmhouse in the region can now be measured against it.

The inscribed timber itself is protected. When the house was designated, the old fragment of the side purlin joint was listed as an tsuketari, a subsidiary item recorded alongside the main designation, counted as one piece. The evidence and the building are held together in the same listing.

Plan is the second reason for the listing. The interior divides east and west: an earth-floored doma work area along the eastern side, and five rooms raised on boards to the west. Running beside the doma was a twelve-mat nakae, the general living room. Above it on the front side sat a four-mat nakaza and an eight-mat zashiki, the formal reception room; behind them ran a long narrow nando sleeping chamber, with the kitchen behind the nakae. This is the widespread three-room hiroma arrangement, but developed a stage further than the standard version, and the Agency's note on the house singles out exactly that: a common plan, refined in its details.

Ownership and scale suggest something about the family. The house is larger than its neighbours and the beams are longer than the local norm, which has led Saga City to describe the Yoshimuras as likely to have been an upper-tier farming household. Their origins are not documented.

Before You Set Out

Read this section before planning a visit, because access to the Yoshimura Residence is not straightforward.

The building is in private hands. The national register lists no owner name, and architectural surveys record the ownership as private. For much of its designated life the interior has been open to visitors, and travel listings still describe the earth floor, the hearth and the cooking range as things you can walk in and see. That situation has not been continuous. In October 2023 Saga City announced that the house was closed to visitors for conservation work including re-thatching of the roof, with the programme scheduled to run through December 2024. The city page carrying that notice has not been revised since.

Anyone travelling specifically for this building should confirm the current position with the Saga City Cultural Properties Division on 0952-40-7369 before setting out. It is a long way to go on an assumption.

The journey itself: roughly 45 minutes by car from the Saga-Yamato interchange on the Nagasaki Expressway, or about an hour by taxi from JR Saga Station. Shōwa Bus services from Saga Station bus centre toward Furuyu and Kitayama serve the valley, with a stop at Kamimutsuro, though the service is infrequent and worth checking the same morning. There is no admission building and no staffed reception.

If the house is shut, the surrounding valley still rewards the drive. Furuyu Onsen, further down the same watershed in Fuji-chō, is an old bathing settlement with day-use baths. Back in the city, the Saga Castle Honmaru History Museum preserves the Shachi-no-mon gate and its attached turret, an Important Cultural Property of 1836 that is open and free. For domestic architecture at this level that you can reliably enter, the former Takatori Residence in Karatsu, an Important Cultural Property of 1904 built for a coal magnate, is open to the public and about an hour and a half away.

One thing worth noticing whenever the house does open. Thatched roofs on this scale are not preserved in a museum sense; they are consumed and renewed. A re-thatching campaign of the kind announced in 2023 replaces a material that the house has been shedding since the last such campaign in the 1980s, when a partial dismantling repair was carried out over the 1982 and 1983 financial years. The building you look at is genuinely from 1789 in its frame and genuinely recent on its surface, and the two facts are not in tension.

Q&A

QCan visitors go inside the Yoshimura Residence?
AThe interior has been open in the past, but Saga City announced in October 2023 that the house was closed for conservation work including re-thatching, scheduled through December 2024, and the notice has not since been updated. Confirm the current status with the Saga City Cultural Properties Division on 0952-40-7369 before travelling.
QHow do I reach the Yoshimura Residence at Kamimutsuro?
ABy car it is about 45 minutes from the Saga-Yamato interchange on the Nagasaki Expressway. From JR Saga Station a taxi takes around an hour. Shōwa Bus services toward Furuyu and Kitayama from the Saga Station bus centre stop at Kamimutsuro, but departures are sparse and should be checked in advance.
QWhy is the Yoshimura Residence an Important Cultural Property rather than a locally listed house?
ABecause its construction date is documented. An ink inscription on the side purlin joint records Tenmei 9 (1789) and a carpenter's name, making it the earliest dwelling in Saga Prefecture with a secure date, and a reference point for dating the region's other suguya farmhouses.
QWhat does suguya mean, and how is the Yoshimura Residence built in that form?
ASuguya describes a farmhouse whose whole plan sits under one straight, unbroken ridge, in contrast to the bent L-shaped magariya found elsewhere in Kyushu. The Yoshimura Residence is a hipped, thatched example measuring 15.1 by 8.4 metres, with a pantiled lean-to added at the rear.
QWhat is the layout inside the Yoshimura Residence?
AAn earth-floored doma occupies the eastern side, with five raised rooms to the west: a twelve-mat nakae living room beside the doma, a four-mat nakaza and eight-mat zashiki at the front, a long nando behind them, and a kitchen behind the nakae. It is a developed form of the three-room hiroma plan.
