An outline description is given of techniques used in Japanese mural paintings, including painting on wooden panels, paintings with coloured lacquer and oil colours, glue painting on earthen and ashlar (tuff) walls with clay or plaster coating. Paintings on wooden panels are in mineral pigments mixed with glue, on white clay or sometimes yellow clay (ochre) grounds. During the Kamakura to Edo periods, there was increased use of panels covered with linen-like cloth, lacquered before painting. Mural paintings on plaster walls are rare; only one pictorial example remains. Architectural decorative patterns used the same technique. During the Edo period, mitsuda-e, a kind of oil painting, used mitsuda oil made by boiling perilla oil or tung oil with mitsuda-so (litharge).
