How should I store a display katana with a lacquered saya?
Updated Mar 2026
Lacquered saya require a few specific care habits. Store the sword horizontally on a katana stand with the edge facing upward - this is traditional orientation and prevents uneven pressure on the lacquer surface. Avoid enclosing the sword in an airtight case for extended periods, as trapped moisture accelerates lacquer crazing and can cause the wooden saya core to swell. Wipe down the saya periodically with a soft dry cloth, and keep the display area away from direct sunlight, which yellows and cracks lacquer finishes over time. The blade itself should be lightly oiled with choji oil every few months to prevent surface oxidation, applied with a soft cloth and wiped to a thin, even coat.
