In the development process of the 132 5. ISSEY MIYAKE project, attempts to explore design from a broader viewpoint - not just limited to clothing - evolved into the IN-EI ISSEY MIYAKE lighting products.

Using materials made from improved recycled polyester fiber, and forms developed by applying three-dimensional mathematical principles, the production of the lighting products involves not only the latest technology, but also conveys the work done by human hands. At the base of the products' concept is the traditional Japanese aesthetics about the relationship between light and shadow (in-ei). The three-dimensional form concept developed by 132 5. ISSEY MIYAKE was used in creating the lampshades, and their original material, with excellent shape retention and light transmission qualities.
