The Koizumi Family Residence Main Building: A Late Edo Farmhouse with a Hidden Sanctuary
Tucked away in the rural countryside of Echizen City, Fukui Prefecture, the Koizumi Family Residence Main Building (Koizumi-ke Jūtaku Shuoku) is a remarkable late Edo-period farmhouse that has stood for roughly two hundred years. Standing at the center of its spacious grounds and facing south, the building draws the eye with its unusual silhouette: a soaring thatched gable rising above layered tile-roofed eaves. Beyond its striking exterior lies an interior plan unlike any ordinary farmhouse — a long axis of rooms arranged in a way that reveals how deeply spiritual life and daily work were once woven together in the villages of Echizen.
Historical Background
The main building is believed to have been constructed during the late Edo period, sometime between the mid-eighteenth and early nineteenth centuries (roughly 1751–1829, with around 1820 often cited as the most likely date of construction). The Koizumi family was a prominent local household in Nikaidō, a farming community in the Echizen plain. In this region, families of standing often hosted village gatherings and religious meetings within their homes, and the layout of the Koizumi residence reflects exactly this dual function as both a working farmhouse and a place of communal life.
Echizen has long been a stronghold of Pure Land Buddhism (Jōdo Shinshū), a tradition that historically relied on the homes of devout laypeople — known as dōjō — to serve as neighborhood worship halls in areas without a nearby temple. The Koizumi residence preserves this dōjō layout in a clearly readable form, offering an unusually intact example of the way faith was practiced in the rural communities of late Edo Echizen. The building underwent careful repair work in 2008, securing its survival into the present day.
Why It Is Designated a Cultural Property
On November 2, 2009, the Koizumi Family Residence Main Building was added to the national register of Tangible Cultural Properties of Japan as a registered structure (Registration No. 18-0081). The Agency for Cultural Affairs recognized it under the criterion of "contributing to the historic landscape of the country," highlighting both its architectural distinctiveness and its value as a surviving witness to the rural domestic culture of the late Edo period.
Two qualities in particular set the building apart. The first is its complex roof composition, which combines a thatched gable-entry hip-and-gable roof at the core with multiple tile-roofed sections wrapping around it — a layered profile rarely seen in a single farmhouse. The second is its specialized interior plan, with a hiroma (great room) at the heart of the house, a doma (earthen-floored work area) to the south, a zashiki (formal tatami room) to the west, and a butsuma (Buddhist altar room) to the north. This unusual arrangement reflects a way of inhabiting space that has almost entirely disappeared from modern Japan.
Architectural Highlights
A Layered Roof That Tells a Story
From a distance, the most arresting feature of the residence is its silhouette. The upper portion of the building rises in an irimoya-zukuri (hip-and-gable) thatched roof entered from the gable end — a steep, dramatic form once typical of the wealthier farmhouses of the Hokuriku region. Tucked beneath and around it, gabled tile roofs cover the side wings and rear, while a deep tile-roofed penthouse skirt (geya) wraps the entire perimeter. The combination of thatch above and tile below is both practical (protecting walls from heavy snowfall and rain) and visually arresting, producing a building that looks layered and almost sculptural when seen from the garden.
The Dōjō-Style Interior
Step through the main entrance and the building reveals its true character. A long doma stretches inward, leading to a raised wooden-plank room (itanoma), then to a fifteen-tatami hiroma, and finally to the butsuma at the far end — all arranged in a single straight line. This sequence is the hallmark of the rural Shinshū dōjō layout, designed so that, on memorial days and other religious occasions, a large congregation could gather and face the family altar together.
To make this possible, the carpenters supported both the itanoma and the hiroma using only four central pillars each, opening up an unusually large interior volume for a building of its age. Visitors with an eye for traditional joinery will appreciate the sheer span of the beams overhead and the graceful logic that ties the whole sequence together.
A Floor Plan Built Around Faith and Family
Beyond the central axis, the western side of the home holds a formal zashiki used to receive guests, while the northern section is anchored by the butsuma. The southern wing was given over to the working life of the household, with the doma serving as a covered workspace. This zoning — sacred to the north, ceremonial to the west, productive to the south — reflects an older Japanese way of mapping daily life onto the cardinal directions.
Visitor Information
The Koizumi Family Residence Main Building is a privately owned property and is not generally open to the public for casual interior visits. The exterior, however, can be appreciated from the surrounding lanes of Nikaidō, where the building's layered roofline and traditional grounds form a characteristic piece of Echizen's rural landscape. Visitors are kindly asked to be considerate of the residents and neighbors when stopping to admire the building, and to refrain from entering the grounds without permission.
The site lies in the eastern part of Echizen City, accessible by car from the JR Takefu Station area in roughly fifteen to twenty minutes. Travelers are encouraged to combine a visit with the many other historic destinations in the surrounding region, several of which are described below.
Surrounding Attractions
Echizen Washi-no-Sato (The Village of Echizen Paper)
About fifteen minutes by car from the Koizumi residence, the Echizen Washi-no-Sato preserves more than 1,500 years of Japanese papermaking tradition. Visitors can watch master craftsmen at work, try their hand at making washi sheets, and visit the Okamoto-Otaki Shrine — the only shrine in Japan dedicated to the goddess of papermaking.
The Takefu Knife Village
Echizen has been a celebrated center of bladesmithing for some seven hundred years. The Takefu Knife Village brings the workshops of the city's master smiths together under one roof, allowing visitors to observe forging in progress and purchase chef's knives directly from the makers.
The Old Townscape of Takefu (Hokkoku Kaidō)
The historic central district of Echizen, which grew up along the Hokkoku Kaidō highway, retains a fine collection of merchant houses, temples, and shrines. A leisurely walk through this area is one of the best ways to appreciate the layered cultural heritage of the surrounding region.

Q&A
- How old is the Koizumi Family Residence?
- The main building is thought to date from the late Edo period, between roughly 1751 and 1829, with construction most often estimated at around 1820. It has therefore stood for approximately two centuries.
- What makes the layout of the house so distinctive?
- The interior follows a so-called dōjō layout: the entrance doma, the wooden itanoma, a fifteen-tatami hiroma, and the Buddhist altar room are arranged in a single straight line. This was designed to allow a large congregation to gather for Pure Land Buddhist services in the home — a tradition once widespread in the Echizen region.
- Why does the roof combine thatch and tile?
- The upper portion is a traditional hip-and-gable thatched roof in the gable-entry style typical of wealthier Hokuriku farmhouses. The tiled side wings, rear roofs, and deep tiled skirt around the perimeter were added to protect the walls from heavy snowfall and rain, producing the building's distinctive layered silhouette.
- Can the interior be visited?
- The residence is privately owned and the interior is not generally open to the public. Visitors are welcome to appreciate the exterior from the public roads nearby, while taking care to respect the privacy of the residents.
