A Storehouse with a Boat Under the Eaves
The Onda Family Residence Storehouse (恩田家住宅蔵, Onda-ke Jūtaku Kura) is a timber storehouse of 1897 at Nichōme, Yashio City, Saitama Prefecture, entered on Japan's national register of Tangible Cultural Properties on 17 February 2022. It stands on private land, the owners live on the site, and the building is not open to the public.
Say that first, because the single most striking thing about this building is something a visitor cannot go and inspect. A wooden boat hangs from the underside of the deep eaves along the west face. It was used for rinsing dye out of cloth in the river, and it was kept where it could be reached in a hurry if the embankments failed.
The Onda family worked in dyeing, the traditional industry of this part of Yashio. They built the storehouse in 1897 and the main house twenty years later, in 1917. Both were registered together in 2022, alongside the main hall of Hachijō Hachiman Shrine, and the three became the first nationally registered cultural properties in the city.
The structure is single-storey in external appearance, tile-roofed, covering about 98 square metres. The record gives it as nine bays along the ridge by three across, using the ken, the traditional bay measure of roughly 1.8 metres. The ridge runs north to south and the building faces west, with the lean-to extending on that side to shelter a working area.
One term deserves attention. This is a shinkabe building: the posts stand proud of the wall surface and remain visible from outside. That distinguishes it from the dozō, the thick-walled plastered storehouse that most people picture when they hear the word kura, where the frame is buried in clay for fire resistance. A farm storehouse in the Nakagawa lowland had different priorities. It needed working space, ventilation and a floor level clear of water.
Dyeing, Rice and Floodwater
Yashio sits on the low ground between the Naka and Ayase rivers, north-east of Tokyo, on ground built up by centuries of flooding. That geography shaped both of the trades this building served.
Dyeing came first. Rinsing long lengths of dyed cloth requires large volumes of moving water, and the rivers supplied it. The boat under the eaves carried the work out to where the current ran. Yashio's association with the craft outlasted the Onda family's own workshop: nagaita chūgata, a stencil-dyeing technique practised on long boards, is designated an Intangible Cultural Property by Saitama Prefecture with holders in this city.
Flooding came with it. When a levee gave way, the same boat became the household's means of escape and of moving goods above the water. Emergency boats kept ready under the eaves were a normal feature of the lowland villages here, and the national record singles this out as the feature that gives the building its regional character.
The interior repeats the logic. A beam runs across the building at roughly the mid-height of the posts, carrying a floor and dividing the space into two tiers, so a single-storey exterior conceals two usable levels. On the lower tier, the northern half is an earthen-floored work area and the southern half is boarded, that boarded portion being partitioned again into two rooms with separate doorways. The second of them counting from the south had its inner walls lined with sheet iron, and rice was stored there. Iron sheeting keeps out rodents, which is reason enough, though a grain store in a district that expected water also benefited from a surface that damp did not rot.
Behind the buildings to the north stands a stand of trees now owned by the city as a preserved grove. Yashiki-rin, the belt of planting kept around a farmhouse to break the wind and supply timber and fuel, is one of the first things to go when farmland becomes housing. Yashio has urbanised heavily since the railway reached it, and the survival of house, storehouse and grove together as a single arrangement is a large part of why the registration criterion applied here was contribution to the historic landscape.
Registration, and How to See Yashio's Heritage
Registration is not designation, and the difference matters here. Important Cultural Properties and National Treasures are designated: the state selects them and controls alterations. Registered Tangible Cultural Properties are registered: the owner gives notice before substantial change, receives tax relief and technical advice, and keeps ordinary use of the building. The system suits properties that are still someone's home, which is exactly the case at the Onda residence.
Yashio City states the position plainly on its heritage pages. The property is privately held, the owners are in residence, and visits are declined. There is no viewing day, no appointment system and no interior access. Photographing into the grounds from the road is not appropriate either. Registration protects the building; it confers no right of entry.
Visitors who want to see comparable architecture in Yashio have good options. The Waida Family Residence, the city's only Important Cultural Property, opens on the third Saturday of each month from 10:00 to 14:00, with August, December and January excepted. Its main house and long gatehouse are thought to date from the mid-Edo period, and the paddy fields immediately south preserve the setting of an upper-tier farming household of the old Hachijō village. The Ōta Family Residence, designated by the city, opens on the same third Saturday and the same hours; the Ōta were river-port merchants from the mid-Edo period, and the main house of around the 1880s is a rare townhouse form in this district.
The main hall of Hachijō Hachiman Shrine, registered on the same day in 2022 as the Onda buildings, stands within a protective outer structure, so what is visible from the precinct is limited, but the shrine grounds themselves are open. The Yashio City Museum holds the local material and is the sensible first stop for anyone approaching the district's history in order.
The Onda storehouse belongs to a category of heritage that is easy to overlook because it cannot be toured. It is a working farm building, put up by a dyer in 1897, adapted to a floodplain, and still standing in a suburb that has otherwise been rebuilt around it. Knowing that the boat is up there under the eaves is most of the point.

Q&A
- Can I visit the Onda Family Residence Storehouse in Yashio?
- No. Yashio City records the property as closed to the public. It is privately owned, the family lives there, and the city asks that visits be refrained from. There is no viewing day, no appointment scheme and no interior access, and photographing into the grounds from the road should also be avoided.
- Why is there a boat hanging under the eaves of the Onda Family Residence Storehouse?
- It served two purposes. The Onda family were dyers, and the boat carried cloth out onto the river to rinse away dye. It also stood ready as an emergency craft for when the rivers of the Nakagawa lowland broke their banks. The national record treats this dual use as the feature expressing the building's regional character.
- Is the Onda Family Residence Storehouse a dozō-style plastered storehouse?
- No. It is built in shinkabe construction, meaning the posts stay exposed on the wall surface, unlike a dozō whose frame is buried under thick clay plaster for fire resistance. As a farm storehouse it was designed for working space, ventilation and flood tolerance rather than fireproofing.
- When was the Onda Family Residence Storehouse registered, and what does registration mean?
- It was registered on 17 February 2022 under number 11-0217, following the Council for Cultural Affairs report of 19 November 2021. Registration is the lighter of Japan's two systems: the owner notifies the authorities before major alterations and gains tax and technical support, whereas designation as an Important Cultural Property requires permission for changes.
- What historic buildings in Yashio can actually be visited?
- The Waida Family Residence, an Important Cultural Property, opens on the third Saturday of each month from 10:00 to 14:00, excluding August, December and January. The Ōta Family Residence, a city-designated property, opens on the same schedule. The grounds of Hachijō Hachiman Shrine are open, though its registered main hall sits inside a protective structure, and the Yashio City Museum covers the local history.
