How should I care for the lacquered saya on a display katana?
Updated Mar 2026
Lacquered saya — whether piano-gloss, crackle-finish, or standard urushi-style — should be kept away from prolonged direct sunlight, which can fade or crack the finish over time. For routine care, a soft lint-free cloth is sufficient for dusting. Avoid using liquid cleaners or abrasives on lacquered surfaces, as these strip the finish layer. Store the saya horizontally or in a dedicated katana stand to prevent warping of the underlying wood core, which can cause the lacquer to develop stress fractures. In humid climates, a silica gel packet placed inside a display case helps maintain stable moisture levels and prevents the wood from expanding and contracting excessively.
