Kita-gura: The Storehouse Attached to the House Itself
Most storehouses on a Japanese estate stand apart. Fire was the reason: keep the plastered box that holds the family's valuables at a distance from the kitchen fires and the lamps. The north storehouse of the former Hirayasu residence in Kawanishi, Hyogo Prefecture, does something different. A roofed extension runs along its front, and the floor of that extension is built as one piece with the covered passage leading back to the main house. You can walk from the living quarters to the storehouse without stepping into the weather.
The building dates from Taisho 7 to 8, 1918 to 1919, the same campaign that produced the rest of the compound. At 60 square meters it is the largest of the group registered alongside it, and structurally it consists of two ranges running east and west, joined together. The base is cut stone laid in courses, kiriishi-zumi, raising the plaster clear of ground moisture.
On the gable wall there is a round opening, a ventilation window, and it is the detail people remember. Stored textiles, documents, and lacquer need air moving through them; a sealed plaster box in a humid Japanese summer is a mould problem waiting to happen. The round form turns a functional requirement into the face of the building. The tatsumi-gura at the southeast corner of the same grounds carries a comparable window, which suggests the two were conceived together.
One note on the record. The Agency for Cultural Affairs commentary describes this as a two-storey storehouse, while the structural field of the same database entry gives it as single storey with tiled roof. The description of two joined ranges with an internal upper level is the fuller account, and both readings are set out in the data table below so visitors can compare what they see.
What Registration Recognizes
Kita-gura was entered in the national register on 7 May 1997, with notification on 29 May, under number 28-0015. The category is Registered Tangible Cultural Property (Buildings) and the ground given is a work establishing a standard of form. The database calls it a high-quality storehouse of the Taisho period.
Registration is not the same as designation. National Treasures and Important Cultural Properties are designated, a selective process carrying tight controls over any alteration. Registration arrived with a 1996 amendment to the Law for the Protection of Cultural Properties and works through notification rather than permission, on the principle that a building kept in use has a better chance of survival than one frozen. Buildings of roughly fifty years or more are eligible, and the system was built with the Meiji, Taisho, and early Showa stock in mind.
Fifteen structures of the former Hirayasu residence hold the status jointly: the main house, the detached rooms, the gatehouse, the entrance and entrance gate, the bathhouse, four storehouses including this one, four sheds, and the roofed wall. Kawanishi City owns the whole. The former residence is also designated by Hyogo Prefecture as an important building for landscape formation.
The Household Behind the Walls
The Hirayasu smelted copper. Their works were the last operating in the Tada silver and copper mining district, whose veins run from Kawanishi, Inagawa, and Takarazuka in Hyogo across into Nose, Toyono, Minoh, and Ikeda in Osaka Prefecture. Extraction is recorded from the late Heian period; the district's height came under Toyotomi Hideyoshi and continued into the early Edo period, when the Shimozai quarter here prospered as a smelting town.
Two generations of works have been located. The Meiji-period plant stood north of where the Hiraga house now sits, identified from period photographs. The Taisho and early Showa plant, northeast of the residence, has been confirmed by excavation and comprised a blast furnace, a mabuki refining hearth, a blower shed, and a chimney. It ran until around 1935. The final refining stage still used the mabuki hearth carried over from the early modern period, so by the standards of a decade in which converters were already available this was a traditional small-scale operation.
A storehouse of this size, connected directly to the house by covered passage, belonged to a family with goods worth protecting and business worth conducting at short notice. The convenience of that passage is not decorative.
Where to Stand
Kawanishi City Museum of Local History opened here in November 1988. Since then the grounds have gained the relocated Hiraga house, an English country-house design of 1918 built for the chemist Hiraga Yoshimi, the Musee Espoir art museum, and the Atelier Hiratsu. The Hirayasu buildings underwent seismic strengthening from October 2023 and reopened to visitors on 12 October 2024.
Approach Kita-gura from the courtyard on the north side of the main house so that the covered passage, the extension floor, and the storehouse front read as the single continuous surface they were built to be. Then move around to catch the gable and its round window.
The museum opens Thursday to Sunday, 10:00 to 16:30, last admission 16:00. Admission is 300 yen for those over 18, 150 yen for 18 and under, with reductions available. Yamashita Station on the Nose Electric Railway is about fifteen minutes away on foot, and thirteen parking spaces are provided. Storehouse interiors are not part of the visitor route; the exhibition rooms, including the mining materials display and the collection of some 920 chopsticks assembled by Isshiki Hachiro, are inside the main house.

Q&A
- What is the round window on the gable for?
- Ventilation. A plastered storehouse holds humidity, and moving air protects textiles, paper, and lacquer from mould. The circular form gives the building its distinctive exterior while doing practical work.
- Why is Kita-gura joined to the main house?
- The floor of the roofed extension in front of the storehouse continues as one construction with the covered passage from the main house, allowing movement under shelter. It is an unusual arrangement for a fireproof storehouse and one of the reasons this building is singled out in the official commentary.
- Is it one storey or two?
- The official commentary describes a two-storey storehouse formed of two joined ranges, while the structural field of the same record gives single storey. The two entries are inconsistent, and both are reproduced in the data table rather than resolved here.
- How many buildings on this site are registered?
- Fifteen structures of the former Hirayasu residence, and separately three of the Hiraga house: the main building, the laboratory wing, and the garden pavilion.
- When is the best time to visit?
- The garden laid out in the Taisho period changes noticeably with the seasons, so spring and autumn suit a slow walk of the grounds. Since opening is limited to Thursday through Sunday, check the museum calendar before travelling.
