How Is Kamakura-bori Made? Wood, Blade, and Urushi

That order distinguishes it from traditional Chinese carved lacquer, diaoqi (雕漆), one of the arts that inspired Kamakura-bori. In diaoqi, many layers of lacquer are built up and the design is carved into the lacquer itself. In Kamakura, craftspeople drew on the woodcarving traditions of Buddhist sculptors and arrived at another method: carve the form into wood, then let lacquer follow its contours.

One sentence explains the difference. It does not explain the work.

A finished object passes through the hands of carvers and lacquerers, through repeated cycles of coating, curing, and polishing, and through moments when timing must be judged by eye and touch. Much of that labor becomes quiet in the completed piece.

Here is how to see it again.

Katsura is one of the principal woods used for Kamakura-bori.

The Traditional Kamakura-bori Cooperative estimates that a katsura tree may need roughly 200 to 250 years of growth before it can provide suitable material. Once cut, the wood may be dried for approximately six months to one year before it is shaped.

This is not empty waiting. Wood continues to respond to moisture. Careful drying helps create a stable foundation for the carving and lacquer that will follow.

Before there is a flower, a blade mark, or a layer of red lacquer, there must be a well-made object. A plate must sit properly. A tray must feel balanced. A box must close as it should.

The undecorated wooden form already carries the future work within it.

The design is drawn to suit the object's shape, scale, and use.

Traditional Kamakura-bori often features flowers and plants, but its visual language ranges from elaborate botanical relief to fields of repeated tool marks. In either case, the drawing is not simply placed on the surface like a printed pattern. It establishes where material will remain, where it will be removed, and how the composition will turn across the object.

At this stage, the color is still only imagined.

What exists is pale wood and a map for the blade.

The carver makes the initial defining cuts, known as tachikomi (たち込み).

Their angle matters. A cut is not merely a boundary around a shape; it helps establish perspective and volume. From those first incisions, the carver removes the surrounding wood and begins to raise the motif from its background.

Different tools perform different work: small knives, flat chisels, round gouges, V-shaped chisels, box chisels, and curved chisels. One tool draws an edge. Another opens a hollow. Another rounds a petal or models the turn of a leaf.

The image does not appear all at once. It emerges cut by cut.

Carving is not only the making of an image. It is the shaping of light.

Raised areas will catch highlights. Recesses will hold shadow. Sloping cuts will change as the viewer moves around the piece. Later, urushi will deepen these effects, but it cannot invent them. The structure must already be present in the wood.

This is why Kamakura-bori cannot be understood from its red color alone. Its character comes from the conversation between surface and depth.

After carving, the object passes into the lacquer process.

Urushi is natural lacquer made from the sap of the urushi tree. It is not simply a glossy red coating added at the end. In a documented traditional process, raw urushi—ki-urushi (生漆)—is first applied across the carved wood and allowed to penetrate it, establishing a foundation for the layers above.

Further foundation work may combine raw urushi with charcoal powder or tonoko (砥の粉), a fine polishing powder. Once the surface has cured, it is carefully polished.

This cycle of preparation and polishing is called togi (研ぎ). It will return between lacquer stages.

The task is delicate: strengthen and smooth the surface without erasing the carving that gives the object its life.

A black middle coat is applied next.

The lacquerer must prevent it from pooling in the carved recesses, where excess material could soften the relief. After curing, the surface is polished again with materials such as whetstone, polishing charcoal, or fine abrasive paper.

For the upper coat, red pigment is mixed into highly transparent lacquer.

The color we eventually read as “red” is therefore not a single, flat layer. It is part of a built surface—carved wood, foundation, dark lacquer, red-toned lacquer, and the finishing work still to come.

This is why the color seems to shift. On a raised edge it may glow. In a groove it may deepen toward brown or black.

Urushi does not behave like ordinary paint. It cures under particular conditions of humidity and temperature, and each stage must reach the right state before the next can begin.

One of the most exacting moments comes after the reddish upper lacquer has been applied but before it has fully hardened.

The surface must be dry enough to receive powder without swallowing it, yet receptive enough for the powder to take hold. Apply it too early and the finish may become undesirably rough. Wait too long and the intended effect may be lost.

This partly cured state is known as hikuchi (乾口). Judging it is not a matter of following a timer alone. The lacquerer must read the material and the day.

At the hikuchi stage, an extraordinarily fine powder may be scattered across the lacquer. The step is called hikuchitori (乾口とり); when makomo is used, it is also known as makomo-maki (真菰蒔き).

The material has an unexpected natural history. Makomo is an aquatic grass in the rice family. The dark powder used in craft is associated with kurobo-kin (黒穂菌), a black smut fungus that develops on the plant. Some Kamakura-bori finishes use susudama (煤玉) powder instead.

Once the powder has settled into the partly cured lacquer, the surface is allowed to harden and is polished back.

The effect is quiet but decisive. Recesses gather depth. Raised carving emerges more clearly. A newly made object acquires a subdued, antique-like tone without pretending to be an antique.

The darkness is not dirt, damage, or accidental patina. It is placed there deliberately.

The final surface is not achieved with one heavy coat.

A thin layer of raw urushi is applied over the piece, then wiped thoroughly with cotton cloth and polished. This may be repeated two or three times, until the desired luster appears.

What remains is less a shell over the carving than a surface joined to it. The lacquer protects and enriches the wood while allowing its relief—and even its blade marks—to stay visible.

The finest effects may be the least insistent: a dark line in a recess, a softened red across a high point, the brief shine along the edge of a cut.

There is no universal production time. Size, carving complexity, finish, weather, and workshop practice all matter.

As one reference point, the Traditional Kamakura-bori Cooperative says that a tray measuring roughly 30 centimeters may take approximately one to one-and-a-half months to complete. The same source gives five to seven years as a rough estimate of the time it can take to become fully proficient in the craft, while noting that this varies by person.

Look again, and several timescales meet in one object:

• centuries of growth in the tree;
• months of drying in the wood;
• weeks of carving, lacquering, curing, and polishing;
• years spent teaching the hands what to do.

Slow production is not an inconvenience added to Kamakura-bori. It is part of what the object is.

Knowing the process changes the eye.

Begin at the edge, where the depth of the wooden form is easiest to see. Follow a carved line and notice where it sharpens, softens, or disappears into shadow. Look for small variations in repeated cuts. Tilt the object slightly and watch the highlights move.

Then look into the darkest recesses.

You are seeing the work of both carving and lacquer: form made in wood, depth developed through color, and traces of the blade preserved beneath the finish.

The object has become easier to read. It has not exhausted its secrets.

For all the skill held in Kamakura-bori, it need not remain behind glass.

The craft itself survived by moving beyond its early Buddhist and ceremonial roles into tea utensils, trays, boxes, and objects for daily life. Use is not a departure from the tradition. It is part of the tradition's continuing story.

This matters to me when I select for Tabibito. I look for pieces with enough presence to be admired on their own, yet enough ease to enter an ordinary day unchanged.

A serving plate may still show the movement of a carving blade while holding fruit, sweets, cake, or food shared with friends. With time and thoughtful use, the lacquer can develop still greater character.

The making does not disappear when the object leaves the workshop.

It begins another life.
