An Oya stone storehouse from the Taisho era
Sakacho Honten Stone Storehouse is a 2-storey stone building in Chuo-cho, Koga City, Ibaraki Prefecture, put up during the Taisho era and listed on 26 September 2000 as a national Registered Tangible Cultural Property.
It runs along the far edge of the Sakacho property, a long low block of pale stone closing off the yard. The walls are laid in cut blocks of Oya stone, a soft volcanic tuff quarried around Oya in Utsunomiya, Tochigi Prefecture. Doorways open at several points along the ground floor, and at each one the jambs and the lintel are single pieces of stone cut long enough to span the whole opening. The roof is Kirizuma-zukuri with Sangawara-buki tiles, and windows sit in the gable walls at the upper level. The Agency for Cultural Affairs records a building footprint of 104 square meters.
The Sato family moved to this block in the early Edo period and worked as money changers before the ninth generation turned the business to wholesale sake. Six buildings from their compound carry the same registration, and Sakacho Honten Stone Storehouse is the youngest of them. The national database places its construction in the Taisho era, between 1912 and 1925.
Scale among the stone storehouses of northern Kanto
The registration criterion applied to Sakacho Honten Stone Storehouse is the one for buildings that set a standard of form. The Agency for Cultural Affairs commentary singles out its size, describing it as belonging to the larger class of stone storehouses in northern Kanto. Its registration number is 08-0034, one of six issued to the Sakacho compound in the twenty-fifth round of registrations.
Stone is the outlier here. The other storehouses on the plot are earthen-walled Dozo-zukuri construction finished in white Shikkui plaster, a technique that had served merchants for centuries. Building in cut stone meant quarried material shipped in, masons who could dress and set it, and a different structural logic at the openings, where mass has to be carried on a beam of stone rather than a timber lintel. That shift belongs to the late Meiji and Taisho decades, when rail freight made Oya stone cheap enough to use at this scale.
Dating rests on the national record rather than on an inscription. Unlike two of its neighbours, the stone storehouse carries no dated ink writing on a beam, so its place in the sequence comes from the Agency's assessment of the era.
Reading the cut stone
Stand at the end of the yard and look along the wall of Sakacho Honten Stone Storehouse rather than at it. The length is the point. Joints run in long horizontal courses, and the stone takes light differently through the day, going almost white at noon and turning grey-green in overcast weather as the tuff absorbs damp.
The openings repay a closer look. Each doorway is framed by two upright stones and capped by one more, all of them cut from single blocks, and the sheer length of those pieces is what the official description draws attention to. Quarrying and moving a lintel of that size was the expensive part of the job.
Look up at the gable end. The windows there are small and set high, lighting the upper floor without weakening the wall, and above them the tiled roof carries the same Sangawara-buki covering used across the compound. That shared roofing is the visual thread tying the stone building back to the plastered storehouses beside it.
Its immediate neighbour is the Middle Storehouse, a white-plastered earthen block. Seeing the two together in one glance is the clearest way to register how far the family's building practice had travelled by the Taisho years.
The hall today, and how to visit
Sakacho Honten Stone Storehouse now holds a small hall with a stage, hired out for concerts and events by the operator of the Koga no Oyasumidokoro Sakacho complex. When a booking is running, the interior may not be open to casual visitors, so the ground floor is easiest to see on a quiet weekday.
The complex opens 9 a.m. to 5 p.m. and closes over the New Year period. Admission is free. The site telephone is 0280-22-2781.
From JR Koga Station on the Utsunomiya Line the walk takes about 9 minutes. Drivers reach it in roughly 30 minutes from the Kuki or Tatebayashi interchanges on the Tohoku Expressway, or about 35 minutes from the Sakai-Koga interchange on the Ken-O Expressway. Three car parks are available: the Sakacho car park, Chuo-cho Hiroba and the Koga Literature Museum.
The operator publishes no photography rule. The exterior can be photographed from the street; for the interior, ask at the reception desk, since exhibitions and private bookings change what is permitted.
