Lighting Products and Fixtures Design Radiance of Nature with Urushi Lighting by Yu Watanabe Derived from sustainably harvested natural sap in Japan, Urushi lacquer is applied to bamboo creating an immersive space amongst tree-like forms. Unlike Western culture, where people remove shadows from space, this project intentionally creates shadows as a part of aesthetic beauty. The columns of Urushi can reflect a candle-like light in a dark room, giving off a luminous glow that gives a sense of the depth of darkness. The unique properties of shape and light create an enchanting interplay of light reflections and shadows evoking a microcosmic space reminiscent of nature.
