Hosoi Family Residence

What the Hosoi Family Residence Is

The Hosoi Family Residence (細井家住宅, Hosoi-ke Jūtaku) is the homestead of an old farming family in Shizukawa, Minamiaizu Town, Fukushima Prefecture, where four buildings put up between the Bunsei era (1818 to 1830) and 1861 have been listed as Registered Tangible Cultural Property since 21 April 1998. In the late Edo period the Hosoi were the village nanushi, the headman family that collected taxes and spoke for the village to the authorities. The Agency for Cultural Affairs describes them as a large farming household and one of the oldest families in the town.

Farming was only part of the business. According to the Agency, the family formally went into sake brewing in 1790. In the twentieth century a post office went up on the property; the Fukushima prefectural list dates it to the early Showa era, with alterations in 1934. Headman, brewer, postmaster: the jobs a leading rural family took on from the late Edo period onward ended up recorded here as different kinds of buildings on a single plot.

Shizukawa is a mountain settlement west of Tajima, the town centre of Minamiaizu. The homestead opens to the road through a gate, with the main house behind it and storehouses set behind and beside the house. Each building is listed separately, but what the listing really protects is the layout of the estate as a whole.

Eight Buildings Listed, Four Removed

When the Hosoi Family Residence was registered on 21 April 1998, it had eight buildings. They carry consecutive registration numbers, 07-0013 to 07-0020: main house, private Buddhist hall, west storehouse, storehouse parlour (kura-zashiki), document storehouse, sake storehouse, post office building and gate. The official gazette notice followed on 9 June 1998. Within Fukushima Prefecture, this was one of the first groups of buildings to enter the registration system.

The dates spread across a long span. The oldest layer is three storehouses from the Bunsei era (1818 to 1830): the west storehouse, the storehouse parlour and the document storehouse. The Buddhist hall followed in 1840, the main house and gate in 1861, the sake storehouse at the end of the Edo period, and the post office in the early Showa era.

Four of the eight, the Buddhist hall, the west storehouse, the storehouse parlour and the post office building, were removed from the register on 10 February 2026. The Agency's list of cancelled registrations files them under removal following demolition or similar alteration. The buildings still listed under the Hosoi Family Residence are the main house, the document storehouse, the sake storehouse and the gate. One discrepancy is worth recording: the cancellation list gives the registration date of those four as 21 November 1998, while the prefectural list and the Agency's database give 21 April. This page follows 21 April.

The surviving four were listed under two different criteria. The main house, document storehouse and gate qualify as contributing to the historic landscape of the country; the sake storehouse qualifies as a model of its type. For both the document storehouse and the gate, the Agency's commentary stresses their value as parts of a large farmhouse compound, so the grouping matters as much as any single building.

How the Estate Is Laid Out

The Agency's descriptions are enough to piece together where the remaining four stand. At the centre is the main house, a single-storey timber farmhouse under a thatched roof with a building area of 246 square metres. The document storehouse sits behind it, toward the west. The sake storehouse lies to the northeast of the main house and is a Tsumairi storehouse, entered from the gable end.

The gate is a Munamon facing the road. When it was registered, it was described as standing just west of the post office building, one of the four later removed. A small stone bridge spans the gap between the road and the gate, and an old estate drawing shows it was already there before 1861. Gate and bridge together keep the entrance looking much as it did at the close of the Edo period.

The main house is now a simple rectangle, a form called sugoya, but it once had a stable wing projecting from the earth-floored side. That L-shaped arrangement is typical of snow country farmhouses in Aizu and Echigo, so the outline of the Hosoi homestead has changed a little since it was built.

Visiting and Getting There

The Hosoi Family Residence is a private home. No opening days or visitor arrangements appear in material published by the Agency for Cultural Affairs, Fukushima Prefecture or Minamiaizu Town (checked 1 October 2026). Plan on the assumption that the grounds and interiors are closed.

From outside, the gate and stone bridge on the road are the clearest things to see. Stay on the public road and do not step onto the property. No signs about photography were found, but this is a lived-in house, so keep windows and people out of the frame. The main house and storehouses are behind the gate, and little of them can be seen from the road.

The nearest station is Aizu-Tajima on the Aizu Railway. The estate lies about 8 kilometres west of the station in a straight line, and a car or taxi is the dependable way to cover that distance. Minamiaizu gets heavy snow, and in winter banks of snow along the road block much of the view around the gate. The snow-free months are the better time to look at the exterior.
