By the middle of the Edo period, a pair of kaioke was an essential component in any set of konrei dogu [wedding furniture], along with more familiar items such as comb boxes, incense sets, writing boxes and basins. The Konrei dogu shoki keisunpo sho [Document on the shapes and dimensions of wedding furniture], dating from 1793, illustrates a typical kaioke on the first page of the first volume and lays down detailed instructions regarding the correct construction, proportions and measurements of a kaioke. Kaioke were used to contained one hundred pairs of clam shells, whose interiors were painted, as in the example associated with this lot, with matching scenes from the Genji monogatari [Tale of Genji] and other courtly texts. These formed the basis of a memory game similar to Western pelmanism. Because each half-shell can only be exactly matched to only one other half-shell, kaioke assumed great symbolic importance in the wedding ceremony itself, and the handing over of the kaioke was a ceremony reserved for the most senior members of the families involved.1
