Former Kusumoto Residence (Wada Residence) Detached Room

The Former Kusumoto Residence Detached Room (旧楠本家住宅（和田家住宅）離座敷, also recorded as the Wada Residence hanare-zashiki) is a late Meiji timber building in the Haradani district of Hidaka Town, Wakayama Prefecture, registered as a Tangible Cultural Property of Japan on 26 February 2021.

Haradani sits at the southern foot of Shishigase Pass, the hardest climb on the Kii-ji, the coastal branch of the Kumano Kodo pilgrimage roads. Travellers who came down the long cobbled descent from the pass reached level ground here, among black bamboo groves and small fields, before continuing towards Gobo and the Hidaka River. The building stands beside that route.

A hanare-zashiki is not a house. The word describes a detached room, or set of rooms, built apart from the main dwelling and reserved for receiving guests. This one was put up in the late Meiji period, between roughly 1898 and 1912, by the Kusumoto family, who were merchants and entrepreneurs. At that time it formed one part of a considerable compound that also held a main house and storehouses. The compound is gone. The guest wing remains.

Built to receive people who mattered

Understanding the building means understanding its job. The Kusumoto family did not use these rooms for daily life; they used them to entertain important visitors. Everything about the construction follows from that.

The plan is a square of four rooms, an arrangement called ta-no-ji, from the character 田 whose four enclosed squares the layout resembles. Rooms open into one another, so sliding partitions can be removed to make a single long space for a gathering, then replaced to make four private ones. Around the outside runs a geya, a lower lean-to roof carried on the four sides of the building, which deepens the shelter at the perimeter and keeps rain off the openings.

The Agency for Cultural Affairs registered the building under the criterion for structures contributing to the historical landscape of the country, recording it as registration number 30-305 in the 98th round of registrations. Its designation is Registered Tangible Cultural Property, a lighter category than Important Cultural Property, intended to protect the large stock of modern buildings that shape Japanese places without carrying national art-historical weight.

Tsuga timber, glass screens, and a carved transom

The building is single storey, roofed with sangawara pantiles over a hipped yosemune form, and covers 112 square metres.

Two details repay close attention. The first is the timber in the principal reception room, which is tsuga, Japanese hemlock, chosen for its dense, tight grain. Among the posts are shiho-masa examples, columns cut so that straight quarter-sawn grain shows on all four faces. Producing one requires a large, slow-grown log and considerable waste, and the result was understood by anyone in Meiji Japan who knew about houses. It was a quiet way of spending money.

The second is glass. A hiroen, a wide wooden veranda, wraps the east and south sides facing the inner courtyard, and it is fitted with glass shoji rather than paper. Sheet glass in a rural Wakayama house around 1900 was expensive and imported, and these screens survive in largely original condition. They change the room: the courtyard stays visible in cold weather, and the light that reaches the tatami is even and cool.

Above the openings, the ranma transoms carry worked detail. Taken together, the materials and the finish mark this out as a high-grade reception space rather than a country outbuilding.

Practical notes before you go

This is a private residence in private ownership. It is not a museum, it has no opening hours, no admission fee, and no interior access. Please view it only from the public road and do not enter the grounds or approach the building. Photography from the road is not restricted; photographing into the property is not appropriate.

The nearest railway station is Kii-Uchihara on the JR Kinokuni Line, about four to five kilometres south of the Haradani area, so most visitors arrive by car or as part of a walk along the Kii-ji. Kii-Uchihara is an unstaffed station with a limited service; rental bicycles have been available near it.

If you are walking, the setting is the point. The site of the Kingyo Chaya, the goldfish teahouse where pilgrims once rested, lies about 1.5 kilometres north, and above it the stone-paved section descending from Kotoge is the longest surviving paved stretch on the entire Kumano Kodo. A memorial stone stele of the Muromachi period stands beside the path near the Hokkedo site. Walking down that way and passing the guest wing gives the building the context the registration text points to: it forms part of the landscape of the Kii-ji.
