The Japanese Urushi Lacquer Art of Restoring Broken Vessels
What Is Kintsugi
"金継ぎ" Kintsugi is a unique Japanese technique in which broken vessels are repaired using urushi(Japanese lacquer).
In Japan, imperfections such as cracks and stains on vessels are considered to create value. The typical way of thinking is that broken vessels must be discarded. However, we believe upcycling gives new life to such vessels and enriches the lives of those who use them. By reviving the spirit of the craftsman, who has poured his or her time into the piece, the vessels can be upcycled rather than being thrown away.
This is what modern, sustainable luxury is all about. We hope that you, too, see the beauty in Kintsugi, a practice which conveys the Japanese spirit.
Finding Beauty in What Has Been Mended
The Philosophy of Kintsugi
Once broken, now traced in gold.
The fractures are not hidden — they are honored. Each seam carries the memory of what happened, and the quiet beauty of what came after.
To Beautiful
From Brolen
At its heart, kintsugi is more than a restoration technique. It is a way of seeing — rooted in wabi-sabi, the Japanese appreciation of beauty in imperfection, impermanence, and quiet humility.
Over a century ago, in The Book of Tea (1906), Japanese scholar Kakuzō Okakura wrote that true refinement lies in the incomplete, the humble, and the transient. Kintsugi gives that idea a tangible form.
At The Kintsugi Labo JAPAN, this philosophy guides every piece in our hands — each golden line a quiet reminder that what is mended can be more meaningful than what was never broken.
Why Urushi — Not Gold — Is the True Heart of Kintsugi
The Soul Beneath the Gold
Urushi lacquer is a natural and sustainable material harvested from the sap of the lacquer tree. This practice has been part of Japanese craftsmanship for over hundreds years. Prized for its strengt adhesion, gloss, and durability, urushi lacquer forms the foundation of authentic kintsugi and is the lifeblood of Japanese lacquer art. Its unique properties enable artisans to restore and preserve objects, creating enduring works of art that reveal a quiet harmony between nature, time, and human hands.
The Power of Urushi: 6 Core Properties
Three Essential Urushi Types for Kintsugi
01: Mugi-urushi
A natural lacquer “glue” made by blending raw urushi with water and finely milled wheat flour. It forms the first bonding layer that holds the broken pieces together with strength and flexibility.
02: Kokuso-urushi
A lacquer “putty” created by mixing raw urushi with water, wheat flour, and powdered zelkova wood. It fills gaps and rebuilds missing areas, forming a durable structure beneath the later lacquer layers.
03: Sabi-urushi
A smooth lacquer “paste” made from raw urushi, water, and tonoko, a refined clay powder. It is used to refine and level the surface after the structural repair, creating a precise base for the subsequent layers of urushi and, eventually, the gold finish.

The Heritage of Urushi and Kintsugi
Long before kintsugi found its name, urushi had already shaped the daily lives of the Japanese for thousands of years. To understand what flows beneath each golden seam, follow the lacquer tree's story across seven chapters of Japanese history — from its earliest origins to the moment kintsugi was born, and beyond.

Where Urushi Begins
Long before written history, the people of Japan had already learned to refine the sap of the urushi tree. Excavations have unearthed lacquered combs and vessels more than six thousand years old — among the earliest known examples of urushi craft anywhere in the world.

The Flourishing of Maki-e
In the imperial courts of Heian-era Kyoto, urushi reached a pinnacle of refinement. Court artisans developed maki-e — sprinkling fine gold and silver powder onto wet lacquer — transforming combs, boxes, and writing instruments into glowing canvases that captured the elegance of aristocratic Japan.

The Seeds of Kintsugi
Under the Ashikaga shoguns, urushi entered a quieter, more contemplative era — shaped by Zen and the rise of the tea ceremony. It was in this period that a celadon tea bowl known as Bakōhan, mended with metal staples after returning from China, is said to have inspired Japanese artisans to seek a more graceful repair — planting the seeds of kintsugi.

The Birth of Export Lacquer
When Portuguese traders and missionaries arrived in Japan at the end of the sixteenth century, they came across urushi for the first time and were captivated by it. They soon commissioned reliquaries, lecterns and devotional shrines from Kyoto's lacquer workshops, fusing maki-e with shimmering mother-of-pearl inlay to create nanban-shikki — the first wave of Japanese export lacquer. These treasures soon sailed back across the oceans to adorn the palaces of cardinals, kings and queens.

1603–1868 · Edo Period
A Golden Age of Lacquer
Peace, prosperity, and a flourishing merchant class made the Edo era the high point of decorative urushi. Master designers like Ogata Kōrin fused poetry, painting, and lacquer into objects of breathtaking beauty — a tradition that captured the imagination of Europe through the export trade known abroad as "Japanning."

Tradition Meets a New World
As Japan opened to the West, urushi artists like Shibata Zeshin found new audiences abroad while preserving centuries-old techniques at home. Later, masters such as Matsuda Gonroku were recognized as Living National Treasures, ensuring that the wisdom of urushi would pass intact into the modern century.

Carrying the Craft Forward
Today, urushi continues to inspire, being preserved by Living National Treasures, taught in master ateliers and reimagined by contemporary artists working in entirely new forms. Kintsugi is one doorway into this world, quietly succeeding the export lacquer tradition that first carried urushi across the oceans four centuries ago. Beyond that lies a living art form where the depth, light and quiet lustre of urushi invite collectors to discover its potential for much more than just restoration.
