Urushi: How Japan's Lacquer Tree Became a Lustrous Everyday Art

A bowl of miso soup tastes a little different in a lacquered bowl. The rim is light and smooth against the lips, the heat stays inside, and the glossy surface, deep red or black, seems to hold light the way still water does. That surface is urushi, the natural lacquer of Japan, made from the sap of a tree and refined by layer after layer of patient handwork.

This guide explains where urushi comes from, how liquid sap becomes a hard, waterproof finish, and why lacquerware has been part of Japanese life since prehistory. It then looks at the decorative art of maki-e, the famous regional centers such as Wajima, the recovery of Wajima's craftspeople after the 2024 Noto earthquake, and simple tips for using and caring for lacquerware.

From Tree Sap to Lacquer

Urushi comes from the lacquer tree, Toxicodendron vernicifluum, which is grown in Japan, China, and Korea and can reach about 20 meters in height. When a tree is around ten years old, workers cut a series of shallow horizontal lines into the trunk and collect the greyish-yellow sap that seeps out. The sap is filtered and sometimes heat-treated or tinted before it is used. The name of its active compound, urushiol, comes from the Japanese word urushi.

In its liquid form the sap can cause a skin rash, so it is handled with care by trained craftspeople. Once cured, it is a different material entirely. Lacquer does not dry by evaporation; it hardens through a reaction that needs warmth and moisture. Coated objects are placed in a humid cabinet, often called a muro, for around 12 to 24 hours per layer, and makers commonly work at about 70 percent humidity. The result is a clear, hard, waterproof film that resists heat and is famously long-lasting.

A Craft With Prehistoric Roots

Lacquer has been used in Japan since the Jomon period. A lacquer tree found at the Torihama shell mound in Fukui Prefecture has been dated to about 12,600 years ago, and lacquered ornaments and vessels from Jomon sites in Hokkaido include a spouted vessel painted in vermilion lacquer that is about 3,200 years old. In the Noto Peninsula, lacquer objects about 6,800 years old have been found at the Mibiki site, hinting at a long local history.

Red lacquer in early times was made with iron oxide or cinnabar, while black came from iron. Unpigmented lacquer is a dark brown, and until the 19th century only a handful of colors, red, black, yellow, green, and brown, were commonly used. Over time, lacquer was applied to wooden bowls, trays, boxes, sword sheaths, musical instruments, and even bows, and the craft grew from a practical coating into one of Japan's great decorative arts.

Maki-e: Painting With Gold Dust

Maki-e (literally sprinkled picture) is the best-known decorative technique. A design is drawn in lacquer, and then fine metal powder, usually gold or silver, is sprinkled onto it and fixed in place. Craftspeople use soft brushes and small bamboo tubes to lay the powder and draw hair-thin lines. The term first appeared in the Heian period (794 to 1185), and a sword scabbard preserved at the Shosoin treasure house from the Nara period uses a similar technique.

Several styles developed over time. In hira maki-e, powder is sprinkled on wet lacquer and covered with another layer. In taka maki-e, repeated layers build a raised, almost sculpted design. In togidashi maki-e, the design is covered in lacquer and then polished back until the pattern appears as if under glass. Other decorations include raden, which is inlaid shell, and chinkin, in which fine lines are engraved into the surface and filled with gold. Together they let a single bowl or box become a small landscape.

Wajima and Other Regional Centers

Japan has many lacquer regions, each with its own character. Wajima, on the Noto Peninsula in Ishikawa Prefecture, dates its lacquerware to the late 15th century, and its oldest surviving piece is said to be a vermilion door at a local shrine made in 1524. Wajima ware is known for its tough base, built by applying many layers of lacquer mixed with jinoko, a powder made from local diatomaceous earth, onto thin zelkova wood. Fabric is applied to bowl edges to reinforce them, and the heritage-designated process is said to involve 124 steps, each handled by a specialist.

Elsewhere, Aizu ware, which developed in the late 16th century, is known for etched designs filled with gold. Tsugaru lacquerware from Aomori is made with many layers of differently colored lacquer to create a mottled pattern, a technique credited to Ikeda Gentaro at the end of the 17th century. Negoro ware, made at a temple complex, uses red lacquer meant to wear away with use and reveal black beneath. Shunkei-nuri applies transparent lacquer over stained wood so the grain shows, and it became popular in Takayama in the 17th century.

Wajima After the 2024 Earthquake

The Noto Peninsula was struck by a strong earthquake on New Year's Day 2024, and Wajima's lacquer community was among the places most affected. One account states that more than 80 percent of lacquerware businesses in the area were damaged, and many workshops were lost. Since then, craftspeople, volunteers, and supporters have worked to rebuild. A project to revive small woodworking workshops rebuilt one traditional turner's workshop in about three months, and younger apprentices are now training there.

By late summer 2024, a report on a recovery tour noted that Wajima-nuri production had returned to its level before the earthquake, helped by the fact that all makers follow the same strict standards, so craftspeople who lost their own workshops could keep working in others. The same report stressed that many challenges remain. Buying a piece of Wajima lacquerware today is one direct way to support the region, and visitors should check official tourism pages for the latest information on reopened shops and galleries.

Living With Lacquerware

Lacquerware is meant to be used. Natural urushi is naturally antibacterial, holds heat well, and tends to grow harder and glossier with decades of use. A bowl for soup or rice, a tray, or a small lidded box can all fit into daily life, and the light weight makes them pleasant at the table.

Care is simple. Wipe the surface with a soft cloth, and if needed use a damp cloth with a little mild soap, taking care not to soak the piece or scrub with abrasive cleaners. Dry it thoroughly afterward. Many makers advise hand washing rather than a dishwasher, so follow the instructions from the shop. Store lacquerware in a cool, dry place away from direct sunlight, since very dry air and strong sun can dull the finish over time.

Plan Your Visit

For a first look at the range of Japanese lacquer, specialist craft shops and museums in Tokyo and other major cities often display pieces from several regions, so you can compare Wajima, Aizu, and Tsugaru in person. Many shops in Wajima and other lacquer towns offer demonstrations or small workshops where you can try decorating a piece. Hours, prices, and reopening status change, so check the official site of each shop or museum before you travel. When buying, ask whether a piece is natural urushi or a synthetic finish, since the care instructions and the price are different.
