Kobatake Residence Detached Wing

A guest wing across the yard from the main house

The Kobatake Residence Detached Wing (古畑家住宅離れ, Kobatake-ke Jūtaku Hanare) is a single-storey timber building in the Nakahata district of Takatsuki, Osaka Prefecture, built in the closing years of the Taisho era (1912-1925) and entered on the national register of Tangible Cultural Properties on 8 July 2008.

It occupies the southwest corner of the Kobatake compound, set across the open yard from the main house. On paper the dimensions are unremarkable: 10 metres along the ridge, 7.0 metres in depth, 74 square metres of floor. The interest lies in how that floor is divided.

Rooms run in two parallel rows, one to the north and one to the south. Both begin at the east end with a doma, the earth-floored working space standard in Japanese farm buildings, continue into a tsugi-no-ma or anteroom, and finish in a principal room at the west. Two routes through one building, running side by side, each arriving somewhere different.

Above them sits an irimoya roof, hipped along the lower slopes and gabled at the ridge, laid with sangawara pantiles.

Registered as a model of form

Japan runs two parallel systems for architectural heritage, and the difference matters for what a visitor can expect to find. Designation (shitei) produces National Treasures and Important Cultural Properties, and binds owners tightly. Registration (tōroku), introduced in 1996, is deliberately lighter: owners keep considerable freedom to live in and adapt their buildings, and the state offers technical advice and modest support in return. Most recognised buildings of the last two centuries are registered rather than designated, and most of them remain in private use.

Registration proceeds under one of three criteria. The Detached Wing entered under the first, which covers buildings serving as a model of form, and carries registration number 27-0486. The Agency for Cultural Affairs treats it as a good instance of the detached reception room in a large modern farmhouse.

The judgement rests on the contrast between the two rows.

The principal room of the southern row carries zashiki-kazari, the built-in fittings that mark a space as formal reception room: typically an alcove for a hanging scroll, staggered shelving beside it, and a shallow desk recess set into the wall. The northern row is handled in sukiya style instead, the lighter idiom that came out of the tea room, favouring slender members, unpainted natural surfaces, and a deliberate asymmetry that departs from the rules governing formal shoin design.

One building, two grades of reception room, with a shared roof over both. The household could seat a caller in whichever register the occasion asked for.

The registration was decided on 8 July 2008 and announced in the official gazette on 23 July, in the sixtieth round of registrations.

A Kyoto building that became an Osaka one

When carpenters raised this wing in the early 1920s, the address was not in Osaka Prefecture. Nakahata was one of five hamlets that had merged in 1889 to form Kashida Village in Minami-Kuwata District, Kyoto Prefecture. The village sat in a basin at roughly 350 metres, ringed by forest, and its water, its road traffic and eventually its bus service all ran south towards Takatsuki rather than north towards Kameoka.

In 1958 the village asked to be transferred. On 1 April that year Kashida left Kyoto Prefecture and joined Takatsuki, the first municipal merger in Japan to cross a prefectural boundary. The blunt tongue of Osaka territory pushing north into Kyoto on any modern map dates from that decision. The Detached Wing never moved; the prefecture around it did.

Eight buildings on the site were registered together in 2008: the main house, this wing, four earthen-walled storehouses along the east and west edges, a rice store, and a nagayamon gatehouse. The main house is the largest at 261 square metres, a tsushi-nikai type with a low upper half-storey and plaster-latticed mushiko-mado windows across its front.

All of it is a private home, still lived in. No visitor entrance has been provided, no opening hours published, and no interior access arranged. The buildings can be seen only from the public road along the eastern edge of the site, where the same courtesy owed to any occupied house applies. City buses from JR Takatsuki Station reach the Kashida district in roughly forty minutes of climbing; drivers need about thirty. Services are infrequent, so the timetable is worth checking before setting out.
