The Journey of Raden in East Asian Art

In East Asian Art, the threads of raden can be traced back to the ancient dynasties of Yin in China, as early as 1700 BCE. Yet, contemporary scholarship lights the paths of the Silk Road, spotlighting a pivotal cultural exchange with Western realms like the Sassanian Empire of Persia, that carried raden to Tang China between 618–907 CE.

Japan's encounter with raden's intricate allure followed shortly after. During the Nara period (714 CE-794 CE), Japanese envoys dispatched to Tang China returned with treasures adorned with raden, including the exquisitely crafted "Eight-lobed bronze mirror decorated on the back with mother-of-pearl inlay" which would later be enshrined among the Shosoin treasures. These artifacts, linked to Emperor Shomu and Empress Komyo, testify to the esteem raden craftsmanship garnered in the Japanese court.

Raden underwent a unique metamorphosis in Japan, shifting from Tang-influenced inlays in wood to those set in lacquer during the Heian period (794 CE-1192 CE). It graced the noble interiors, adorning furniture such as inkstone boxes and lidded chests named karabitsu. By the Kamakura period (1192 CE-1333 CE), Japanese raden artisans transcended plain surfaces, embellishing even irregular planes with pictorial motifs—a proof of their evolving prowess.

The Fabulous and Refined Technique of Raden

The raden technique involves carefully cutting and embedding thin pieces of mother-of-pearl into lacquerware. Once the desired design is achieved, additional layers of lacquer are applied over the shell pieces to seal them in. Once the black lacquer covers the shells, the craftsperson carefully polishes the surface until the shells reappear. The depth created by the thick layers of lacquer gives the lacquerware a three-dimensional effect, making the shell inlays appear as if they are floating. As the light hits the surface, the blue shells, subtly hidden beneath the layers, shimmer and reflect light, offering an unparalleled visual delight. Crafting a pair of chopsticks with raden typically spans a duration of about four months.

Wakasa Lacquerware: A Chronicle of Artistry

The early styles of the Kikujin-nuri design show how various plants and shells were inlaid onto lacquer. 

Wakasa lacquerware from Obama City in Fukui Prefecture has passed on the raden technique for generations, starting in the early years of the Edo period (1603 CE- 1867 CE) when a merchant, Kumiya Rokurōzaemon, gifted a Chinese lacquered zonsei, "Starlit" tray, to lord Sakai Tadakatsu. Admiring its beauty, Tadakatsu asked Matsu-ura Sanjuro, a local lacquer master, to produce a similar tray. Inspired by both the zonsei and Wakasa Bay's marine scenery, Sanjuro created the Kikujin-nuri, lacquerware that captured the complexity of the bay's seabed in its enchanting design. Subsequently, Tadakatsu bestowed upon this shell-embellished craft the name Wakasa lacquerware.

Wakasa lacquerware begins with multiple layers of lacquer applied to a wooden base, followed by the addition of various adornments. Common designs besides the iridescent raden include rankaku made from crushed quail eggshells, and okoshi-moyo created with inlays of pine needles or rapeseed.

The lacquer is meticulously polished, revealing the embedded patterns beneath—a technique known as togidashi, unique to Wakasa lacquerware, ensuring that no two patterns are identical. 

Wakasa lacquerware employs a variety of natural elements such as pine needles, flowers, and even grasses. This diverse incorporation of materials not only results in captivating patterns but also reinforces the connection to nature, making each piece a subtle reflection of the world outside.

This tea canister from Yatsuyanagi is decorated with a falling sakura (cherry blossom) motif using shell inlays, taking advantage of the natural beauty of cherry bark and colorful shine of the mother-of-pearl adornments. The lustrous brown cherry bark is characterized by its moist texture and beautiful luster. The inside is also made of cherry bark, which is moisture-proof and antibacterial, preserving the flavor of the tea leaves put inside.

The cherry trees used for Akita cherry bark work are mainly wild cherry trees from the Tohoku region. These trees, sculpted by the harsh climate, are celebrated for their beauty and resilience. The cherry bark is carefully peeled off from the trunk and left to dry in the shade for a year or two to remove the moisture.

Through centuries of refinement and mastery, craftspeople like Furui Masahiro and establishments like Yatsuyanagi have elevated humble materials into symbols of beauty and prestige. The transformation of blue shells, cherry bark, and lacquer into items of such elegance as the Matsukan chopsticks and the kabazaiku tea canister underscores a reverence for tradition that transcends mere aesthetic. As an invitation to appreciate the timeless dialogue between art and nature, raden resonates with every polished inlay and every sweep of lacquer.
