What is Urushi?

Urushi is a natural resin obtained from the lacquer tree (Urushi-no-ki) and plays a significant role in the traditional crafts of East Asia, including Japan, China, and Korea. Due to its durability, waterproof properties, and beautiful gloss, urushi has been used in various applications since ancient times.

The History of Urushi

The history of urushi is very old, with the earliest examples of its use dating back to around 5000 BCE. In Japan, urushi has been used since the Jomon period, and many lacquered artifacts have been discovered through archaeological excavations. During the Nara and Heian periods, the techniques for making lacquerware and decorations developed significantly, and urushi crafts became particularly important in aristocratic culture.

Production and Processing of Urushi

Urushi is harvested by making incisions in the bark of the lacquer tree, a process called "kaki," which requires very delicate skills. The collected raw urushi cannot be used as is and needs to be refined. The raw urushi is processed into "refined urushi" by removing impurities and stirring or heating it.

The process of lacquerware production is very labor-intensive and involves many steps. First, a base coat of urushi is applied to the substrate (wood, bamboo, fabric, etc.), and then a reinforcing layer of cloth is added. Next, middle and top coats are applied repeatedly, and finally, the piece is polished to finish. During this process, urushi must be kept at a specific humidity and temperature, and drying can take several days to weeks.

Characteristics and Uses of Urushi

Urushi is used in a variety of applications due to its properties. Firstly, it has very high waterproof and durability, making it widely used in everything from everyday items to decorative objects and building materials. Lacquered utensils and furniture become more beautifully glossy with use and can be cherished for a long time.

Additionally, urushi is known for its beautiful gloss and deep colors, especially black and red urushi. These colors are achieved by mixing pigments, allowing for diverse expressions. Furthermore, techniques like maki-e and raden enable elaborate decorations using gold, silver, and shells.

Modern Applications of Urushi

In modern times, while traditional urushi craftsmanship is preserved, new applications are also being explored. For example, urushi's antibacterial and preservative properties are being noted in medical products, and its use as an eco-friendly natural material is advancing. In the fields of contemporary art and design, urushi's unique texture and expressiveness are valued and incorporated into various works.

The Protection and Future of Urushi

Traditional urushi craftsmanship faces challenges such as a shortage of successors and declining demand. However, efforts continue to rediscover its value and charm and to pass it on to the next generation. Schools and workshops for learning urushi techniques are being held in various places, and there are also movements to open new markets through international exchanges.

From ancient times to the present day, urushi has continued to captivate people with its beauty and functionality. It is hoped that its tradition and techniques will continue to be inherited and develop in new forms in the future.
