How should I store a red or green lacquer saya long-term?
Updated Mar 2026
Lacquer is sensitive to humidity extremes and direct sunlight. For long-term storage, keep the saya in an environment with 45–60% relative humidity — too dry and the lacquer can develop hairline cracks, too humid and it may soften or develop mold on the wooden substrate beneath. Avoid displaying the sword in direct sunlight or near windows, as UV exposure causes red lacquer in particular to fade toward orange over time. A horizontal sword stand indoors, away from heating vents and exterior walls, is the standard recommendation. Wipe the saya surface periodically with a soft, dry cloth. Never use silicone-based polishes on lacquer, as they can cloud the finish over repeated applications.
