What kumiko means
Kumiko is the lattice of fine battens joined vertically, horizontally and diagonally in shoji screens, transoms and lattice doors. The battens are notched and fitted together, usually without nails, and the way they are combined can form geometric patterns such as hemp leaf, tortoise shell and diamond; the whole technique of forming these patterns is also called kumiko.
Fine patterns demand well-seasoned timber and precise dimensions, and they show a joiner's skill clearly. Modern Japanese-style houses and inns often made intricate kumiko in the shoji, transoms and desk-alcove screens of their reception rooms a highlight.
Reading the records
Records mention kumiko as a design highlight. The owner's residence of the Ochiairō inn in Izu, Shizuoka, is recorded as showing early Showa craftsmanship and the owner's taste in its elaborately designed kumiko fittings and carefully chosen materials. The retirement house of the Shono family in Saga is a modern Japanese-style shoin noted for fine kumiko in the framed shoji between room and veranda, the transoms and the desk-alcove screens.
On site, look closely at how the battens of shoji and transoms are joined; closely crossing battens forming a pattern are kumiko.
