How should I care for a lacquered saya on a displayed wakizashi?
Updated Mar 2026
Black lacquer saya require modest but consistent care to maintain their finish over years of display. Keep the saya away from direct sunlight, which can cause lacquer to fade or crack along the grain of the underlying wood. Relative humidity between 40 and 60 percent is ideal — environments that are very dry can cause the wood substrate to contract and stress the lacquer surface. Dust with a soft, dry cloth only; avoid cleaning products that contain solvents or alcohol. For the blade itself, a light application of camellia oil (choji oil) on the steel surface every few months prevents surface oxidation, particularly in coastal or humid climates. Store the wakizashi horizontally on a proper stand rather than standing blade-down, which can put uneven stress on the habaki fitting where blade meets saya.
