A headman's house on the south shore of Lake Tega
The main house stands near the centre of the Someya grounds, facing east across a wide forecourt. It was built in 1847, the fourth year of the Koka era, the year after a fire swept the property, and the family records say it was roofed in tile from the start rather than the thatch usual for the district at that time.
The Someya were the headmen, or nanushi, of Washinoya village. Their lineage reaches back to a local warrior family of the medieval period, and by the Edo period they combined farming with sake brewing, silkworm raising and pawnbroking, keeping a sake shop in Edo as well. A house of this scale was the working seat of that authority.
Why the building matters
The main house carries the registration criterion reserved for buildings that serve as a standard of design, a step above the criterion applied to the seven other structures on the site. With a building area of 344 square metres it ranks among the largest farmhouses in the western part of Chiba, and it is read as a benchmark for late-Edo farmhouse form in the region.
Its plan is a magariya, an L-shaped layout in which the earthen-floored work wing bends forward from the north end of the front. A formal step-entrance, the shikidai, marks the south end, where guests of rank were received. This pairing of a rough working wing and a formal reception end within one roof is what makes the plan legible as a headman's house.
What to look for on a visit
Step into the doma, the packed-earth work floor, and the restored cooking hearth comes into view. The 2020s restoration rebuilt the kamado, and on some event days the local preservation group lights it and cooks rice over the wood fire. The lattice doors of the doma filter the morning light in long bars across the floor.
Inside, rooms open off the eighteen-mat room at the centre of the front, with the innermost southern room finished as the formal zashiki that looks onto the south garden. From the tatami you see the garden the way the family meant guests to see it, over stepping stones toward a mossed pond and low artificial hill.
The residence opened to visitors in October 2024 after a restoration that ran for several years. It is open on Sundays only, from 10 a.m. to 4 p.m.; admission is 500 yen for adults, 200 yen for high-school and university students, and free for younger children. The grounds sit above the south shore of Lake Tega in the Washinoya district of Kashiwa, Chiba. From Abiko Station on the JR Joban Line it is about five kilometres; buses also run from Kashiwa Station.
