The last house of the Shinkuruwa quarter
The Isshiki Family Residence Main House (一色家住宅主屋, Isshiki-ke Jūtaku Omoya) is a thatched samurai dwelling of 1863 in the Nishimanabecho district of Tsuchiura City, Ibaraki Prefecture, and it became a Registered Tangible Cultural Property in 2001.
Its story begins with a piece of town planning. In 1863 the Tsuchiura domain laid out an entirely new samurai quarter on the edge of Hitana village, a large tract divided into plots according to stipend and settled by 160 retainer households recalled from the domain's Edo residence. The quarter was called Shinkuruwa, the new enclosure. A branch of the domain school Ikubunkan, founded in 1799, was built inside it so that the children of the transplanted families would not lose their schooling.
The building now registered was put up in that year for the Nishikawa household, another Tsuchiura retainer family. It was moved to its present plot during the Meiji era by Isshiki Hanchū, third head of the Isshiki family, who had served the domain as a senior retainer and who went on to found the Fiftieth National Bank, the first bank of its kind in Ibaraki. That bank later merged into what is today the Joyo Bank. Almost everything else in Shinkuruwa has gone. The Isshiki Family Residence Main House is the only samurai dwelling from the quarter still standing.
Why it carries a national listing
Japan runs two separate schemes for historic buildings. Designation is the older and stricter one. Registration, created in 1996, is lighter and is aimed at buildings still in ordinary use, obliging the owner only to notify the state before altering the exterior. The Isshiki Family Residence Main House entered the register on 28 August 2001 under the criterion that it contributes to the historic landscape of the country, and it is listed as a Registered Tangible Cultural Property rather than designated.
What the listing recognises is scarcity of a specific kind. Tsuchiura kept its castle gates and its merchant storehouses, but the residences of its samurai class were almost entirely swept away. The Agency for Cultural Affairs record describes this building as the sole surviving samurai house of the Shinkuruwa development, and the city has separately designated it a Historic Scenery Building, the fifth on that list.
The connection to Isshiki Hanchū adds a second layer. A house built for a domain retainer in the last decade of samurai rule, then bought and moved by the man who brought modern banking to the prefecture, sits exactly on the seam between two Japans.
What to look at
The plan is the thing to notice first. Four rooms of eight tatami mats each are set in a two by two square, the arrangement Japanese carpenters call the rice field pattern after the character 田. Sliding partitions between them can be taken out entirely, which is how a house of this size could hold a formal gathering. A wooden Engawa veranda wraps the north and south faces, so light enters the interior from two opposite sides and the rooms read differently depending on the hour.
Above sits a Kayabuki thatched roof in Yosemune-zukuri form, hipped on all four sides. Thatch of this depth is now rare anywhere near a city centre in the Kanto plain, and the roof is what makes the building visible from a distance. The registered footprint is 201 square metres.
Behind the house is a garden in the Enshū manner, with a low artificial hill and a pond, laid out to be seen from the tatami rooms rather than walked through. The full property, garden and wooded slope included, runs to about 3,600 square metres. A separate wing was added on the south side in 1989 and is not part of the registration.
Visiting the Isshiki Family Residence Main House
Be clear about this before travelling: the Isshiki Family Residence Main House has no regular opening hours. It served as a restaurant under two successive operators, from 1979 to about 2007 and again from 2009 to about 2019, and has been closed since. The Isshiki family transferred the house, the garden and the surrounding land to Tsuchiura City in 2021, and the city has been running a public call for private partners to bring the building back into use, with a cafe, a small guesthouse or a training facility among the options under discussion. Until an operator is appointed there is no ticket and no scheduled tour.
The thatched roof and the front garden can be seen from the lane outside, and photographing the exterior from public land is not restricted. The house stands in a lived-in residential neighbourhood, so keep off the driveway and do not photograph over the boundary hedge. Anyone wanting to know the current position on access should contact the cultural affairs section of Tsuchiura City, which holds the building.
Getting there is straightforward. Nishimanabecho is about ten minutes by car from Tsuchiura Station on the JR Joban Line, roughly fifty minutes from Ueno by limited express and local train. Cyclists have an easier time still, since the Tsukuba Kasumigaura Ringring Road passes close by and is the reason the city has floated the idea of a rest stop here. Walking from the station takes around forty minutes across flat ground.
Access details and the utilisation plan were checked in September 2026. Both may move quickly once a partner is chosen.

Q&A
- Can I go inside the Isshiki Family Residence Main House?
- Not at present. The house closed as a restaurant around 2019 and was transferred to Tsuchiura City in 2021. The city is seeking a private operator, and no opening hours, tours or admission fee exist in the meantime. The exterior can be viewed from the public lane.
- How do I get to the Isshiki Family Residence Main House from Tokyo?
- Take the JR Joban Line to Tsuchiura Station, about fifty minutes from Ueno. From the station the site is roughly ten minutes by taxi or forty minutes on foot. The Tsukuba Kasumigaura Ringring Road cycle route runs nearby if you are riding.
- Is photography allowed at the Isshiki Family Residence Main House?
- Photographing the roof and the frontage from the public road is fine. The grounds are private property held by the city and are not open, so do not enter or shoot over the boundary. Neighbouring houses are occupied, which is worth keeping in mind.
- How old is the Isshiki Family Residence Main House and who built it?
- It was built in 1863 for the Nishikawa household, a Tsuchiura domain retainer family, in the newly laid out Shinkuruwa samurai quarter. Isshiki Hanchū moved it to the present site during the Meiji era and lived in it.
- What is worth seeing near the Isshiki Family Residence Main House?
- The site sits between the Ringring Road and central Tsuchiura, so it is easy to combine with the castle grounds at Kijo Park about twenty minutes away by bicycle. Check opening days for anything you plan to enter, since this house itself cannot be visited.
