Nishiyama Family Residence Connecting Corridor

What Is the Nishiyama Family Residence Connecting Corridor?

The Nishiyama Family Residence Connecting Corridor (西山家住宅渡廊下, Nishiyama-ke Jūtaku Watari-rōka) is a roofed wooden walkway of about 1940 linking the main house and the Western-style building of the Nishiyama Family Residence in Okamachiminami, Toyonaka City, Osaka Prefecture, registered as a Registered Tangible Cultural Property of Japan in 2007.

The national record describes a single-storey timber structure with a tiled roof and an area of 15 square meters, registration number 27-0435. One ken (about 1.8 meters) wide, it carries a gabled roof of interlocking tiles and slopes gently down from the front of the Western-style building's entrance, at the east end of its north face, to the open veranda at the southwest corner of the main house.

It was designed by Takao Okada of the Mitsukoshi department store's Osaka housing division, who also remodeled the tea room. Toyonaka City's preservation plan says it was finished in 1939, a year earlier than the government's "about 1940". Either way, it belongs to the same campaign of work as Mirei Shigemori's garden.

Why the Connecting Corridor Was Registered

The Nishiyama Family Residence Connecting Corridor became a Registered Tangible Cultural Property on December 5, 2007, under the criterion for structures that contribute to the historic landscape of the nation.

The Agency for Cultural Affairs singles out the way it merges with the artificial hill of the garden. The preservation plan goes further. It argues that the corridor is far more than a passage: it pulls together Shigemori's garden and three buildings of quite different style, the main house, the Western-style building and the detached wing, and it calls the corridor the most distinctive space in the whole residence.

What to Look For at the Connecting Corridor

Closed on one side, open on the other

The two sides of the Nishiyama Family Residence Connecting Corridor could hardly be more different. The west side, facing the back of the plot, is a solid Shinkabe wall broken only by a few small lattice windows. The east side, facing the garden, is left open between a low clay-plastered parapet and a narrow strip of wall hanging from the beam. Even the foot of the parapet is pierced, so from the garden the corridor looks as if it floats.

For anyone walking it, the garden appears in a long horizontal frame between parapet and hanging wall. Toyonaka City describes this as a device for viewing the garden from a changing point of view, and as the corridor turns and climbs, the picture of Seiryūtei inside the frame shifts with every few steps.

Woven ceiling, patterned floor

Overhead is an ajiro ceiling of woven strips of wood. The eaves show their rafters, and brackets of bark-on logs sit atop the posts. Sand-finished plaster and bamboo appear in the walls. Underfoot, the floor is a washed finish of small black Nachiguro pebbles, set with square paving tiles in groups of four laid on the diagonal like stepping stones. Okada knew tea architecture intimately, and it shows in these details; it is worth walking slowly and looking down.

Feet in the garden

During the 1940 redesign, earth was banked right up against the raised Western-style building and this corridor and planted with groups of stones. Shigemori's own plan shows a stone arrangement on the mound east of the corridor. Stand on the garden side and the base of the building seems to run straight into the slope.

Visiting the Connecting Corridor

The Nishiyama Family Residence Connecting Corridor lies inside the walls and is not open on a regular basis. It can be seen during the talks, tours, tea gatherings and other events held by Toyonaka City. How much of the site you can walk depends on the event, so follow the guidance given on the day about walking the corridor itself (checked October 2, 2026).

For the best view of its open east side, look across the garden from both the main house veranda and the veranda of the detached wing. You will see the slope of the corridor and the long gap between parapet and hanging wall. Photography rules are set for each event. Directions are on the Nishiyama Family Residence page.
