What Is Urushi?
Urushi, or natural lacquer, is a traditional coating made from the sap of the lacquer tree. It has been used in East Asia for thousands of years. Long before synthetic coatings existed, it was already applied to everyday objects—bowls, tools, containers—not only for decoration, but for durability.
It comes from a tree called Toxicodendron vernicifluum. The sap is carefully collected by hand through controlled tapping, then refined into usable lacquer. The process is slow and labor-intensive, and the yield is limited. This is one of the reasons urushi has always been considered a valuable material.
There is no shortcut in how it is made.
A Process Defined by Layers
Unlike modern coatings that are applied in a single step, urushi is built gradually.
It is applied in thin layers, one at a time. Each layer must cure in a specific controlled environment before the next can be added. Depending on the object, this process can take weeks or even longer.
Time is not separate from the material.
Time is part of it.
A Surface That Becomes One with the Object
Once fully cured, urushi forms a surface that is both durable and subtle. It is resistant to water, long-lasting, and develops a depth that synthetic materials rarely achieve.
It does not simply sit on top of an object.
It bonds with it.
Because it is a natural material, no two finished surfaces are exactly the same. Slight variations in tone, texture, or depth are not imperfections—they are part of its nature.
Safety and Stability
Raw lacquer can cause skin irritation before it has fully cured. This is one of the most common questions about the material.
However, once properly cured, urushi becomes stable and safe. For centuries, it has been used in tableware, containers, and drinking vessels.
Its safety is not a modern discovery.
It is a long-established condition of its use.
A Different Relationship with Time
Compared to modern synthetic coatings, urushi is slower, more dependent on handwork, and less predictable.
It does not aim for absolute uniformity.
Instead, it preserves traces of the process itself.
Each layer reflects a moment in time—when it was applied, how it cured, and how the environment shaped it.
In this sense, the surface is not only a finish.
It is a record.
Why It Is Still Used Today
Urushi continues to be used today not only because of tradition, but because of its material qualities.
It is durable, stable, and develops character over time. With use, it does not simply wear out—it changes subtly, becoming more integrated with the object it protects.
In a world of fast production and instant finishes, urushi remains defined by patience.
It cannot be rushed.
It cannot be replaced by speed.
In Our Work
In our pieces, we choose urushi for these reasons.
It allows each object to carry the trace of time and process.
Not as decoration.
But as structure.
And in that structure, each piece becomes slightly different—shaped not only by design, but by the material itself and the time it takes to complete.
