A Farmhouse in the Granite Hills of Kasama
The Tomita Family Residence Main House (富田家住宅主屋, Tomita-ke Jūtaku Omoya) is a large single-story farmhouse at Uchikawa in the Ogoto district of Kasama City, Ibaraki Prefecture, added to the national register as a Registered Tangible Cultural Property on 31 October 2022. The Agency for Cultural Affairs dates the building to the early Meiji period and gives a construction range of 1868 to 1882.
Ogoto sits in the northwestern corner of the city, in a pocket of low hills and paddy fields. Granite has been quarried here since the Edo period, and the cuttings left by that trade are still scattered through the surrounding woods. The register entry puts the house squarely in that working landscape. Assessors describe it as the main house of a farm in a stone-producing village, and the criterion applied was its contribution to the historic character of the Japanese countryside.
Its floor area is 342 square meters. For a rural house of this date in central Ibaraki, that is a great deal of room.
Nail Covers Bearing a Daimyo Crest
What separates the Tomita Family Residence Main House from the ordinary run of surviving farmhouses is the quality of its formal rooms. The Kugikakushi fitted over the joints in the guest wing carry maru ni mitsu-gashiwa, three oak leaves inside a ring. That was the crest of the Makino family, who held Kasama Domain through the later Edo period. Kasama City reads the match as a sign that the house was built by a household with close ties to the domain lords.
The sources are not in complete agreement about when that happened. The Agency for Cultural Affairs records the building as early Meiji. Kasama City, which owns it, describes the house as standing by the early Meiji years, and in a later consultation paper the city widened the estimate to somewhere between the late Edo period and early Meiji. The house has not yielded a dated ridge tablet, so the range is an inference from the woodwork and the fittings rather than a documented fact.
Either way, the result is a building that sits between two traditions. The frame and the working half belong to farmhouse practice. The reception rooms follow warrior-class convention, with the kind of joinery a village headman would have needed when an official came to call.
Reading the Plan: Earth Floor North, Guest Rooms South
The house faces east, and the reception rooms look south onto the garden. The northern half is given over to a very broad Doma together with the everyday living room; the earth floor runs about 5 ken across, wide enough that farm work and cooking could go on inside without crowding. South of it, past an entrance room, three Zashiki run in a line, and the last of them steps out of the main block as a tsunoya, a projecting wing at the far corner.
At the center of the east front is a Shikidai entrance, the raised board threshold that marks a formal doorway rather than a family one. Follow the rooms through to the innermost one and the fittings become steadily more elaborate: a Tokonoma, a low reading window, a Tsukeshoin alcove desk, and a tenbukuro cupboard set high in the wall. This is Shoin-zukuri joinery of a standard rarely met in a working farm.
Look up in the transoms above the sliding screens and you find Osa-ranma, panels of fine closely spaced slats named after the reed of a weaving loom. They filter light without opening the rooms to view.
Outside, the roof is Irimoya-zukuri covered in Sangawara-buki pantiles, and the eaves are carried on a dashigeta, a purlin thrown well forward of the wall line on projecting brackets. It is a heavy, deliberately assertive detail, and from the lane it is the first thing that tells you this was not an ordinary house.
Visiting the Tomita Family Residence Main House
The Tomita Family Residence Main House is not open for general visits. Kasama City acquired the property and has been trying since registration to find a private operator who will restore the building and run it as lodging or as a place to eat, and until that arrangement is settled there are no published opening hours, no admission charge and no visitor facilities. In the consultation document the city filed with the Ministry of Land, Infrastructure, Transport and Tourism, it set a target of starting work in fiscal 2026 and opening to the public the following year, marking both as provisional.
Anyone who wants to see the interior should write to the Cultural Promotion Office of the Kasama City Board of Education before travelling. The office has arranged supervised site inspections during each round of the call for operators, so access is possible in principle, but not on a walk-up basis. No photography policy has been published; assume that pictures inside require permission.
Getting there is straightforward by car and awkward without one. Kasama City gives the driving time from Kasama Station on the JR Mito Line as 10 minutes. The site covers 2,766.59 square meters and holds 3 further buildings besides the registered main house, set back from a narrow lane that the city planned to widen along the north edge of the plot. There is no bus route to the hamlet, and the nearest shops are back toward the centre of Kasama.
If you are in the district anyway, the quarry faces in the hills around Ogoto explain the house better than any label could. The stone trade paid for rooms like these.

Q&A
- Can I visit the Tomita Family Residence Main House, and is there an admission fee?
- Not on a walk-up basis. The house is owned by Kasama City but has no published opening hours, no admission charge and no visitor facilities, because the city is still selecting a private operator to restore and run it. Supervised inspections have been arranged during each call for proposals, so it is worth contacting the Cultural Promotion Office of the Kasama City Board of Education in advance.
- What kind of building is the Tomita Family Residence Main House?
- A single-story timber farmhouse with a tiled roof and a floor area of 342 square meters. The northern half holds a broad earth-floored work space and the family living room; the southern half holds three formal guest rooms in a row, the innermost one projecting from the main block as a corner wing.
- Why was the Tomita Family Residence Main House placed on the national register?
- It was registered under the criterion of contributing to the historic character of the Japanese landscape. The assessors singled out its position in a stone-quarrying village, the assertive projecting eaves, and formal reception rooms of unusually high standard for a farmhouse.
- When was the Tomita Family Residence Main House built?
- The Agency for Cultural Affairs assigns it to the early Meiji period, with a range of 1868 to 1882. Kasama City has also described it as possibly reaching back into the late Edo period. No dated ridge tablet has been found, so the dating rests on the carpentry and fittings.
- How do I reach the Tomita Family Residence Main House?
- Kasama City puts it 10 minutes by car from Kasama Station on the JR Mito Line, in the Ogoto district in the northwest of the city. There is no bus service to the hamlet, so a car or taxi is effectively required.
