Chujoke Jutaku Omoya (Chujo Family Residence Main House)

A Farmhouse That Outlasted Its Village

The Chujo Family Residence Main House (中條家住宅主屋, Chūjō-ke Jūtaku Omoya) is a mid-Meiji farmhouse in Akagawa 4-chome, Asahi Ward, Osaka City, entered on Japan's national register of Tangible Cultural Properties on 6 August 2025 under registration number 27-0947. It is the first building in Asahi Ward to hold that status.

Asahi Ward is now solidly built up, a low-rise grid of housing pressed between the Yodogawa embankment and the rail lines. Akagawa was farmland for most of its history, and this house stands inside what was the village settlement. The Chujo family were among the principal landholders of Akagawa village from the Edo period onward. The building itself dates to the middle Meiji years, with work carried out again in the early Showa period; the Agency for Cultural Affairs gives the construction span as 1883 to 1897.

The place name has a longer reach than the house. Akagawa takes its name from Akagawa-dera, a Tendai Buddhist temple that stood here in the Muromachi period and burned during the Osaka Campaign of 1614 and 1615. It was never rebuilt. Hiyoshi Shrine, founded as the temple's guardian shrine, outlived it. Most of the shrine's buildings were destroyed in the air raids of 1945 and were put back afterwards. The Chujo house sits a short distance west of it.

What "Registered" Means, and Why This House Qualified

Japan sorts its architectural heritage into tiers. National Treasures and Important Cultural Properties are designated (指定, shitei): the state selects them, and almost nothing can be altered without permission. Registered Tangible Cultural Properties (登録有形文化財, tōroku yūkei bunkazai) sit below that. The category was created in 1996 for buildings roughly fifty years old or more, and it works by notification rather than permission. An owner who wants to modify a registered building tells the authorities; they do not have to ask. The system was built for structures that are still lived in, worked in, and modified.

The Chujo house was registered under the first of the three criteria, which covers buildings that contribute to the historic landscape of the country. The Council for Cultural Affairs recommended it on 21 March 2025, and the Ministry of Education, Culture, Sports, Science and Technology published notification No. 63 on 6 August of that year under Article 57, paragraph 1 of the Law for the Protection of Cultural Properties.

The reasoning is straightforward once you know the geography. Osaka absorbed the farming villages that fed it, and the physical evidence of those villages has mostly gone: to fire, to war, to redevelopment. A farmhouse of this age surviving inside the ward boundary is unusual enough that the Council's report noted its future use was still under discussion.

Reading the Building from the Street

The main house is a two-storey timber structure with a tiled roof and a building area of 157 square metres. The upper level is a tsushi-nikai, a low attic storey tucked under the roof rather than a full second floor, which is why the elevation looks heavier and lower than the floor count suggests. The roof is irimoya, hipped at the lower slopes and gabled at the ridge, and it is framed degeta-zukuri: the purlin is carried on brackets projecting past the wall line so the eaves reach well out over the façade. Wide lean-to roofs, called geya, run along the south and west sides. Together these give the front an overhang deep enough to throw the entrance into shadow at midday.

Two features on that front elevation are worth slowing down for. One is the ōdo, an oversized sliding door that opens the earthen-floored work space to the yard; farmhouses needed an aperture large enough to move tools, crops and carts through. The other is the lattice windows flanking it, a survival of an older facade type that most Osaka houses lost long ago.

Inside, the plan divides cleanly. The western third is doma, packed-earth floor, the working half of the house. The eastern portion holds six rooms in a regular arrangement, and the southeast corner carries the formal room with a butsuma, the Buddhist altar space, together with a tokonoma alcove and a hira-shoin, a low writing alcove set beneath a window.

The detail that architectural historians single out is the absence of a staircase. There is no fixed way up to the attic storey. A ladder is set against the wall of the four-and-a-half-mat room at the northwest, and a wooden panel in the ceiling slides open to admit whoever is climbing. That arrangement is original and has never been replaced with anything more convenient. The daikokubashira, the principal post of the house, is a 30-centimetre square of tsuga (Japanese hemlock), a costly timber that says something about what the family could afford.

Practical note for anyone planning to look: this is a private residence and there is no interior access. The exterior can be seen from the public road, and photography from the street is fine, but the site is someone's home and there are no visitor facilities, no admission desk and no opening hours. The nearest station is Shirokita-Kōendōri on the JR Osaka Higashi Line, which opened in 2019 in Akagawa 1-chome; the house lies north of it, near Hiyoshi Shrine and the Yodogawa embankment, roughly a ten-minute walk. Osaka City's Asahi Ward office publishes photographs of the exterior if you would rather look before travelling.
