What is the best way to store a blue lacquer saya long-term?
Updated Mar 2026
Piano and standard lacquer saya are susceptible to humidity fluctuation, which can cause the lacquer to crack or lift from the wood substrate over time. Store your saya in an environment maintained between 45-60% relative humidity - a climate-controlled room or a display case with a passive silica gel pack works well. Avoid placing lacquered saya in direct sunlight, as UV exposure yellows clear lacquer and fades colored finishes. When storing the sword inside the saya for extended periods, apply a very light coat of choji oil to the blade first to prevent surface oxidation within the enclosed space. Do not use petroleum-based products on the saya's exterior surface, as these can soften lacquer over time.
