Recent years have seen a rise in the belief that taking breaks and naps are an important factor for improving productivity in offices. "We want to make a product that meets the needs of our times," Koyoju Plywood President Hironari Yamaguchi told a news conference in Sapporo on July 14. The license agreement signed on the same day allows the plywood manufacturer based in Asahikawa, Hokkaido, to use Itoki's patent-pending technology. The city is a regional hub of furniture manufacturers in Hokkaido. According to Itoki's design, the nap box is equipped with ledges to support the head, hips and knees to prevent the user from falling over.
