How should I store a dark red tsuba katana to protect the fittings?
Updated Mar 2026
Storing a katana with red lacquered or enamel-finished tsuba requires a bit more care than plain iron fittings. Avoid direct sunlight, which can fade pigmented lacquer and dull the crimson tone over time. Humidity is the main structural concern: fluctuations above 60% relative humidity accelerate corrosion on the carbon steel blade and can cause the lacquer on fittings and saya to bubble or peel. A horizontal katana stand inside a display case with a silica gel pack provides the most stable environment. For the blade itself, a thin application of choji oil every two to three months creates a protective barrier against oxidation. When handling the piece for display adjustments, use cotton gloves to prevent the oils in your skin from etching the polished surface.
