How should I care for a lacquered saya on a gold-fitted aikuchi?
Updated Mar 2026
Lacquered scabbards require a few simple but consistent care habits to stay pristine on display. First, avoid prolonged direct sunlight — UV exposure gradually yellows or fades colored lacquer finishes, particularly red and black tones. Store the piece either in its display box or on a horizontal sword stand away from windows. Second, keep the saya away from sudden humidity changes; lacquer can develop hairline cracks if the wood substrate expands and contracts rapidly. A stable indoor environment at 40–60% relative humidity is ideal. Third, wipe the saya surface only with a soft, dry cloth — avoid any solvent-based cleaners, which can strip the lacquer's topcoat. For the blade inside, remove it periodically, apply a thin coat of choji oil or mineral oil with a soft cloth, and ensure the blade is completely dry before resheathing, as trapped moisture under lacquer can cause interior spotting over time.
