What Is the Omori Family Residence North Wall?

The Omori Family Residence North Wall (大森家住宅北塀, Ōmori-ke Jūtaku Kitabei) is a roofed timber wall that runs west from the main house of the Omori merchant family along the old Kikuchi Ōkan road in Yamaga, Yamaga City, Kumamoto Prefecture, built around 1940 and registered as a Registered Tangible Cultural Property on 27 March 2018. It is 20 meters long and has a tiled roof.

Starting at the western end of the main house, the Omori Family Residence North Wall follows the street and closes off the north side of the lot. Yamaga City's list of cultural properties presents it as the wall facing the Kikuchi Ōkan.

A Plastered Face for the Street

The Omori Family Residence North Wall stands on a base of cut stone. Its street face is Ōkabe, a thick wall that hides the posts, finished in lime plaster according to Yamaga City. Under the eaves the plaster is built up in stepped moldings, a cornice known as Nokijabara.

A street face with no exposed wood follows the same thinking as the east wing of the main house, whose walls are plastered right up to the eaves. The Agency for Cultural Affairs credits the Omori Family Residence North Wall with shaping the historic streetscape together with the house. Seen from the road, house front and wall read as one continuous surface running along the street.

Carpentry on the Garden Side

The inner face of the Omori Family Residence North Wall is a contrast. Here it is Shinkabe, with the posts left visible, and Udeki arms cantilevered from the posts carry the eave beam. Under each arm sits a Mochiokuri bracket carved with a decorative pattern, the kind of ornament Japanese carpenters call eyō.

The eave soffit is lined with boards, and the roof is a pitched Kirizuma-zukuri laid with Sangawara-buki pantiles. The street gets a fire-resistant plaster face; the garden gets the carpenter's work. One wall, two quite different finishes.

The Omori Family Residence North Wall is registration number 43-172, listed for its contribution to the historic landscape.

Visiting

The outer face of the Omori Family Residence North Wall can be seen at any time from the old Kikuchi Ōkan. From the opposite side of the road, the cut-stone base, the plain plastered face and the stepped cornice are all in view at once.

The inner face with its brackets looks onto the garden of a private home and cannot be seen from outside. Please stay off the property and keep clear of passing traffic when you stop to look.
