What oshiita means
An oshiita is a shallow thick board set against the wall of a reception room. A scroll hangs on the wall and flowers, an incense burner or candlestick stand on the board before it. It arose in the Muromachi period as a place for displaying paintings and objects and is regarded as the forerunner of the Tokonoma.
Where the tokonoma is a recess with a raised floor and depth of its own, the oshiita is a simpler setup of a board along the wall with little depth. Even later, some houses gave the principal room a tokonoma and an anteroom an oshiita, matching the display space to the rank of the room. Records also call it an oshiita alcove.
Reading the records and the room
Records mention it within the layout of reception rooms. The entrance and reception wing of the Tanaka family house, the Sukematsu honjin, in Izumiotsu, Osaka, joins a ten-mat and an eight-mat room in an L; the ten-mat room has an oshiita at the east end of its north wall, and the eight-mat room has an alcove, shelves and a built-in desk. The fixtures grow more complete toward the inner room, showing oshiita and tokonoma used according to rank. The jōdan-no-ma on the first floor of the keep of Inuyama Castle, a National Treasure, is described as a shoin-style room with an oshiita alcove, staggered shelves and ornamental doorway.
On site, look at the depth and height of the board against the wall. A shallow board set along the wall is an oshiita; a deeper recess forming a space of its own is a tokonoma.
