How should I store a lacquered saya wakizashi to protect the finish?
Updated Mar 2026
Lacquer is durable but sensitive to prolonged direct sunlight and extreme humidity fluctuations. For long-term display, position the piece away from south- or west-facing windows where UV exposure is highest. A horizontal display stand is preferred over vertical mounting, which can stress the koiguchi (saya mouth) over time. If storing rather than displaying, wrap the saya loosely in a soft, acid-free cloth - avoid plastics, which can trap moisture. The blade itself should be lightly oiled before storage; draw it clear of the saya, apply a thin layer of choji or mineral oil with a soft cloth, and allow it to settle before resheathing. Check the piece every few months and reapply oil if the surface appears dry or shows any early discoloration.
