The importance of being natural urushi

Development of new material for urushi lacquer

  • Decline of the urushi lacquer industry

    Urushi has been used in life and culture of Japan for 9000 years, and it is still known as the craft representative of Japan.
    However, due to the change in lifestyle, demand for lacquerware has decreased, and its industry is now drastically declining.

  • Utilizing lacquer in harmony with modern lifestyle

    For 25 years, we had worked as a specialist in repairing lacquerware in Tama City, suburb of Tokyo, and were keen to convey the urushi culture.
    We discovered through repairing job that we could utilize in modern life the excellent lacquering techniques of the late Edo period . Therefore, in 2003, we established Duco Co., Ltd. and started developing new base materials fit for urushi lacquer.

  • Lacquer as a new material

    We started to focus on the base material for coating lacquer to find something other than wood we had used so far. After repeating chemical experiments,we finally succeeded in developing the completely new lacquer materials in which the properties of both urushi and the base blend. That is, transparent material such as glass/acrylic onto urushi. Or, metal such as titanium onto urushi. Not a simple "lacquer + base" product but a new lacquer material both in function and design.

  • New design and diversity

    Developing the new base material of glass, acrylic, titanium, engineered stone or optical lenses enabled us to discover the new designs that genuine natural urushi brings.
    With them the target of use were also expanded and varied, leading way to modern architecture, room interior designing, or to art.
    It also expanded the new sales channels, and now helps to find paths for urushi lacquer industry in new field different from traditional craft.

  • Collaboration with other industry under our technology

    While we respect the value and the quality of urushi lacquerware as traditional craft, we have been aiming to encourage the demand of urushi products in daily life.
    After having developed materials other than wood, we started to collaborate with companies from different industries, and succeeded in sharing the value of urushi culture with their products.
    The representative is the golf club set of Majesty Golf & Co., Ltd., a golf manufacturer in Tokyo.
    The club head was lacquered and decorated with hand-drawn maki-e.
    It was introduced as traditional Japanese technique and sold in Taiwan, India, China and Korea.

Traditional beauty inherited in new expression

Culture inheritance

In tea ceremony, we have made in the space of 2 tatami mats, a small world, where we can feel the four seasons, the nature and the universe through the transition of seasons or light of day and night.
Duco's ”Ice-Light” conveys the concept of ”creating cosmic space” pursued in tea ceremony, and creates the world through lighting. This is how we inherit the culture of tea ceremony.

Photo: ”Ice-Light”, optical glass table light, whose four sides are decorated with traditional maki-e. The pictures are lit up from inside by LED light installed at the base.
Inheriting traditional beauty and technique, we created a new expression of cubic art with distant landscape and nearby scenery. A small world inside the glass.
