How should I store and maintain a lacquered maroon saya?
Updated Mar 2026
Lacquered saya should be stored away from direct sunlight and significant humidity fluctuations, both of which can cause the lacquer surface to crack, fade, or peel over time. A horizontal display position on a dedicated katana stand reduces stress on the koiguchi — the scabbard mouth — and prevents warping. The blade inside should be lightly coated with a thin layer of choji oil or camellia oil before long-term storage to prevent oxidation; this is especially important for high-carbon steel blades like T10, which are more reactive to moisture than stainless alternatives. Avoid storing the blade in the saya for extended periods in humid climates, as trapped moisture accelerates surface oxidation. Wipe the exterior of the saya with a dry, soft cloth periodically to remove dust without abrading the finish.
