What should I know about caring for a white lacquer saya?
Updated Mar 2026
White lacquer saya are finished with multiple coats of urushi-style lacquer or synthetic lacquer, which creates a smooth, sealed surface that is moderately resistant to humidity but still requires care. Avoid resting the saya in direct sunlight for extended periods, as UV exposure can yellow or micro-crack lacquer finishes over time. When storing, keep the sword horizontally in a display rack or sword bag rather than upright, which reduces pressure on the koiguchi fitting. Wipe the saya surface occasionally with a soft, dry cloth — never use solvents or abrasive polishes, as these strip the lacquer sheen. If the saya develops surface scratches, a light application of furniture wax (non-silicone) can restore gloss temporarily. The blade itself should be cleaned and re-oiled with choji oil every few months, particularly in humid climates, to prevent rust forming on the T10 carbon steel surface.
