A 1939 House at the Head of a Nagasaki Valley
The Ayukawa Residence Main House (鮎川家住宅主屋, Ayukawa-ke Jūtaku Shuoku, also listed as Ayukawa Family Residence Main Building) is a timber dwelling of 1939 in Yamauchi-men, Tabira-chō, Hirado City, Nagasaki Prefecture, entered on Japan's national register of Tangible Cultural Properties on 23 October 2008 under registration number 42-0083.
The site lies in a short valley running inland, north from the fishing harbour of Hinoura. Water is close enough to smell, yet the slopes on either side close the property off from the working noise of the port. The house covers 317 square metres of ground, rises to two storeys over part of its plan and drops to one over the rest, and carries a tiled roof throughout.
Reading the roofs is the quickest way into the building. At the core sits a two-storey block with its ridge running east to west, roofed in the irimoya form: a hipped lower slope with a gable perched above it, the most formal of the standard Japanese roof types. East of that block, a single-storey wing takes the fully hipped yosemune form. West of it, a simple gable, kirizuma, closes the composition. Lean-to geya roofs run along the north and south faces. Three roof types in one building, set at three heights, and from a few steps up the hillside they stack into terraces of grey tile.
Two doorways open on the south side. One is the genkan, the formal entrance where guests were received; the other is the uchi-genkan, the family's everyday door. Follow the guest route and it ends at the south-east corner of the house, where the principal reception room is fitted with zashiki-kazari: the built-in display alcove and shelving that mark a room's rank. The Agency for Cultural Affairs describes the building as an example of modern Japanese-style domestic architecture with finely judged detailing.
Who built it is a question with a partial answer. Nagasaki Prefecture, which lists the property among its townscape assets, records that the client was Ayukawa Jingoemon, a mining engineer descended from the family of the Hirado domain lords, and that the design is attributed to Ogawa Yōkichi. Ogawa is remembered for taking first place in the 1912 competition for a new Osaka City Hall while working as a technician for the Government-General of Taiwan; Kataoka Yasushi and the municipal building office developed his scheme into the neo-Renaissance hall completed in 1921. No published drawings tie Ogawa to this house, so the attribution rests on the prefectural account rather than on documentary proof.
The sources also disagree on the date. Nagasaki Prefecture gives Meiji 14, which is 1881. The Agency for Cultural Affairs database and the Cultural Heritage Online record both give Shōwa 14, or 1939. This article follows the national database as the primary source, and notes the discrepancy rather than smoothing it over.
Registered, Not Designated: What the Category Means
Japan sorts its architectural heritage into tiers, and the distinction matters here. National Treasures and Important Cultural Properties are designated, a status that comes with tight controls on any change. Registered Tangible Cultural Properties are registered, a lighter category created in 1996 for buildings generally more than fifty years old. Owners notify the authorities before altering more than a quarter of the exterior, but they keep considerable freedom otherwise. The category was built to catch the enormous stock of Meiji-era and later buildings that would never clear the bar for designation, and to let owners go on living in them.
The criterion applied to the Ayukawa main house is the one covering works that serve as a model of design. That is a judgement about the quality of the architecture itself. The stone walls and steps on the same property were registered the same day under a different criterion, the one for structures contributing to the historic landscape of the country. Two criteria, two registrations, one estate.
The date carries its own significance. By 1939 Japan was two years into full-scale war in China, and timber controls and the conscription of skilled craftsmen were about to bite. A house of this quality, with the carved ranma transom panels and delicate shōji screen work that the prefectural description singles out, sits at the closing edge of a period when good material and good carpenters could still be had.
Nagasaki Prefecture added the whole ensemble, main house and stonework together, to its register of townscape assets on 26 March 2010 under the number Keishi 2-130.
Getting There, and What You Can Actually See
Set expectations first: this is a private home and it is not open to the public. Nagasaki Prefecture's listing states that interior visits are by advance appointment only and gives 0950-57-0066 as the contact number. Anyone hoping to see inside should call first and accept that the answer may be no. Arrangements change without notice, so it is worth also contacting Hirado City's Cultural Exchange Division on 0950-22-9143 or the Hirado Tourism Association. The house was opened on occasion during the Hirado Domain Garden Tour, a city event that ended in 2019.
Photography should likewise be treated as requiring the owner's consent. Looking at the roofline and the stone walls from the public road is another matter, provided you stay off the property.
What rewards attention. The roofs, first: the three forms read as a single composition only from slightly above, so walk a little way up the lane rather than standing square in front. Then the pair of south doorways, and the logic behind them. Separating the guest entrance from the family entrance was common in houses of this class, but here the formal route runs straight through to the south-east corner room, the corner that catches morning light and the longest view down the valley.
Trains reach Tabira-Hiradoguchi Station on the Matsuura Railway's Nishi-Kyūshū Line, about ten minutes on foot from the house and sharing the same address block of Yamauchi-men. The station claims the title of westernmost in Japan among ordinary railways operating under the Railway Business Act, and part of its building houses a small railway museum, free to enter during opening hours. From Sasebo the ride takes roughly an hour and a half. By car, leave the Nishi-Kyūshū Expressway toward Matsuura and follow Route 204.
Tabira has one more building worth the detour. Tabira Church (田平天主堂), a red-brick basilica begun in December 1915 and completed in October 1917, was designed and built by Tetsukawa Yosuke, who put up church after church across Nagasaki. It carries the higher status of Important Cultural Property. Seeing a designated brick church and a registered wooden house within ten minutes' drive of each other gives a clear sense of how the two tiers work. Cross the Hirado Bridge and the old castle town waits, where the Saiwaibashi bridge and the walls of Hirado Castle use the same Aō basalt found in the Ayukawa stonework.

Q&A
- When was the Ayukawa Residence Main House built, and when was it registered?
- The Agency for Cultural Affairs database gives 1939 as the construction year. Registration as a Tangible Cultural Property took effect on 23 October 2008 and was published on 10 November of the same year, under number 42-0083 in the sixty-first round of registrations. Nagasaki Prefecture's own listing gives 1881 instead, a discrepancy left unresolved in the published sources.
- Can visitors go inside the Ayukawa Residence Main House?
- Not without arranging it in advance. The house remains a private residence and is normally closed. Nagasaki Prefecture lists interior viewing as by prior appointment on 0950-57-0066. Call before travelling, since access depends on the owner and can change. The exterior can be seen from the public road, but the grounds are private.
- How do you reach the Ayukawa Residence Main House by train?
- Take the Matsuura Railway Nishi-Kyūshū Line to Tabira-Hiradoguchi Station, roughly ten minutes on foot from the property and in the same district of Yamauchi-men. The journey from Sasebo takes about ninety minutes. The station is the westernmost in Japan among ordinary railways and keeps a free railway museum inside the station building.
- What makes the Ayukawa Residence Main House architecturally distinctive?
- A two-storey irimoya-roofed block running east to west forms the core, with a hipped single-storey wing to the east, a gabled section to the west, and lean-to roofs along the north and south faces. The building covers 317 square metres. Two entrances open to the south, and the principal reception room in the south-east corner carries a full set of built-in display fittings.
- Who designed the Ayukawa Residence Main House?
- Nagasaki Prefecture attributes the design to Ogawa Yōkichi, winner of the 1912 competition for the Osaka City Hall, and names the client as Ayukawa Jingoemon, a mining engineer from a family connected to the Hirado domain lords. The national database records no architect, so the attribution comes from the prefectural account alone and should be treated as such.
