How should I store lacquered saya to keep them in display condition?
Updated Mar 2026
Lacquered saya are more sensitive to environmental conditions than the blade itself. The primary concerns are humidity fluctuation and direct sunlight. High humidity can cause the lacquer to lift or blister at the seams where the wooden saya halves are joined, while extremely dry conditions can cause cracking. Aim to store pieces in an environment between 45-60% relative humidity. Keep them away from windows or any light source with significant UV output, as prolonged exposure fades lacquer pigment - particularly relevant for the deep red and blue finishes in this collection. A horizontal display stand reduces stress on the habaki and prevents warping. For long-term storage, wrapping the saya lightly in acid-free cloth before placing it in a case adds a useful buffer against dust and contact scratches.
