Chinkin: The Sunken-Gold Carving of Wajima Lacquerware
8 min readRun a fingertip across a piece of Wajima lacquerware decorated in chinkin (沈金) and you will feel almost nothing. The gold is there — fine lines of it, sometimes whole flocks of cranes or fields of autumn grasses — but it sits inside the surface rather than on top of it. Chinkin, written with characters meaning "sunken gold," is Japan's carved gold-inlay technique for urushi lacquer: the artisan engraves a design into cured lacquer with a fine chisel, rubs fresh urushi into the cuts as an adhesive, and presses gold leaf or gold powder into the grooves. What remains after the excess is swept away is a drawing in buried gold.
This Urushi Studies article follows Wajima-nuri and maki-e with a closer look at chinkin. It is particularly associated with Wajima in Ishikawa, where engraved lines and stippled points give lacquer decoration a distinctive precision.
What Is Chinkin?
Chinkin is a decorating technique applied to a prepared lacquer surface. The artisan engraves shallow lines or points, then introduces fresh lacquer and metal into those recesses. The number of ground and finish coats varies with the object and making process.
Gold enters last. Raw urushi is rubbed into the carved lines, acting as a glue; gold leaf or fine gold powder is pressed over the surface and settles into the wet grooves; the excess is cleaned away. The gold that stays behind sits flush with or just below the surrounding lacquer — sunken, sealed, and protected.
Chinkin (沈金) — at a glance
- Meaning: "sunken gold." The metal sits in carved grooves below the lacquer surface, not on top of it.
- Method: engrave cured urushi → rub raw urushi into the cuts → press in gold leaf or powder → sweep away the excess.
- Signature effect: crisp, engraved linework — hairlines, feathers, wave crests — that flashes only when light strikes at an angle.
- Home ground: strongly associated with Wajima in Ishikawa, while also practised elsewhere.
- Care: recessed decoration still needs gentle handling; lacquer and metal can be damaged by abrasion or unsuitable cleaning.
From Qiangjin to Chinkin: How Sunken Gold Reached Japan
Like many of Japan's lacquer techniques, chinkin descends from a Chinese ancestor. In China the method was called qiangjin (戧金, "incised gold"), and lacquer decorated this way was being made during the Song and Yuan dynasties. Trade carried examples across the sea, and by the Muromachi period (1336–1573) imported qiangjin wares were treasured in Japan — studied, collected, and eventually answered in kind.
Japanese lacquerers did what they have always done with imported ideas: they absorbed the method and bent it toward local taste. Where much Chinese incised-gold work favors dense, filled compositions, Japanese chinkin came to prize the eloquence of the single line — a reed, a bird's wing, the crest of a wave — surrounded by generous black silence. By the Edo period (1603–1868), as Wajima's lacquer industry matured into its famous division of specialized labor, chinkin had become one of the town's two signature decorating arts, alongside maki-e.
How Chinkin Is Made: Carve, Rub, Gild
A chinkin artist's toolkit centers on the chinkin-nomi — small chisels whose blades are ground into different profiles for different marks. The work follows a strict sequence:
- Design transfer. The motif is drafted on paper and transferred faintly onto the polished lacquer surface.
- Carving. The artist cuts the design into the cured urushi. Line carving (suji-bori) produces continuous engraved strokes; dot carving (ten-bori) builds tone from thousands of tiny points, the way an etcher stipples shadow. Angling the blade changes the width and character of every mark.
- Lacquer as glue. Raw urushi is rubbed across the carving and worked down into the cuts, then the surface is wiped almost clean — lacquer remains only in the recesses.
- Gilding. Gold leaf or gold powder is pressed over the design and adheres where the wet urushi waits. Silver, platinum, and colored pigments can be applied the same way.
- Finishing. Once the urushi in the grooves has cured, the excess metal is swept off and the surface is cleaned. The gold now lives inside the lacquer, flush with the surface.
The linear nature of the craft was long considered its boundary — an engraved stroke is either there or it is not, with none of maki-e's soft gradients. Wajima carvers spent the modern era pushing against that limit, and one of them, Mae Taihō, later recognized as a Living National Treasure for chinkin, showed how far dot carving could go: fields of stippled points dense enough to model fur, feathers, and three-dimensional form out of pure engraving.
Chinkin and Maki-e: Two Roads to Gold
Japan's two great gold-decorating techniques for lacquer solve the same problem from opposite directions.
| Chinkin 沈金 | Maki-e 蒔絵 | |
|---|---|---|
| Gesture | Carving — the design is cut into cured lacquer | Painting — the design is drawn in wet lacquer, then gold is sprinkled on |
| Where the gold sits | In grooves, below the surface | Above the surface, or polished flush in togidashi maki-e |
| Character of line | Engraved crispness; hairline precision | Painterly softness; blooms and gradients |
| Strengths | Fine linework, stippled tone, geometric clarity | Clouds, mist, scattered gold fields, relief effects |
| Wear over decades | Recesses offer some protection, but lacquer and metal can still wear | Wear depends on the technique, finish, use, and care |
The two are collaborators more than rivals — plenty of masterpieces carry both. If you want the full story of the sprinkled-gold side, our study of maki-e covers it in depth. And the instinct is not confined to lacquer: Japanese porcelain developed its own gold-on-color language in kinrande, the "gold brocade" style, which reads like chinkin's ceramic cousin.
Chinkin in Wajima
Chinkin is practiced across Japan's lacquer regions — Tsugaru, Yamanaka, Kyoto, and Aizu among them (see our study of Tsugaru-nuri for how differently a region can think about lacquer) — but Wajima and chinkin are nearly synonymous, and the reason is under the surface.
Wajima-nuri combines prepared wooden bases, ground layers, and lacquer finishes. Chinkin carvers work on the lacquered surface, using lines and points to create their motifs. Ishikawa Prefecture’s account of chinkin explains the process and its development in Wajima; it does not require treating every other lacquer ground as unsuitable.
Wajima's craft community was struck hard by the Noto earthquake of January 2024, which destroyed workshops and historic streets across the town. Rebuilding a craft that depends on generations of accumulated specialization is slow work, and it continues. It is one more reason honest Wajima pieces — carved by hand, gilded line by line — deserve to be understood and valued.

FAQ: Chinkin, Answered
Is chinkin decoration real gold?
Traditionally, yes — gold leaf or fine gold powder, bonded into the carved lines with raw urushi. Silver, platinum, and colored pigments are also used, and some contemporary work mixes metals within one design. Inexpensive souvenir pieces sometimes carry printed imitation "gold" patterns instead, which is one reason provenance matters.
What is the difference between chinkin and maki-e?
Direction. Chinkin cuts the design into cured lacquer and fills the cuts with gold — subtractive. Maki-e draws the design in wet lacquer and sprinkles gold onto it — additive. Chinkin excels at crisp engraved lines; maki-e excels at soft gradients and raised effects. Many fine pieces use both.
Is chinkin the same as kintsugi?
No. Kintsugi is a repair practice for broken ceramics — urushi joins the fragments, and the seam is dusted with gold. Chinkin is a planned decoration for intact lacquerware. They share materials, urushi and gold, but not purpose; our guide to kintsugi tells that story.
How can I tell hand-carved chinkin from a printed imitation?
Look closely at engraved lines and points to understand the surface, but do not rely on reflections or small irregularities as an authenticity test. Ask for the maker’s name, process description, and supporting records. Photographs alone may not distinguish all printed, engraved, or mixed techniques.
How should I care for chinkin lacquerware?
Exactly as you would any fine urushi piece: hand-wash gently with lukewarm water and a soft cloth, no dishwasher, no microwave, no long soaking, and no abrasives — the gold is protected in its grooves, but the surrounding lacquer still dislikes harsh treatment. Our urushi care guide covers the full routine.
Can chinkin pieces be used every day?
Modern pieces intended as tableware can be used according to the maker’s instructions. The condition of the base, lacquer, and decoration matters. Antique, damaged, or display-only pieces need individual assessment before food use.
