A three-dimensional puzzle object crafted from reclaimed pieces of Japanese wood (hinoki, kurogaki and more) assembled using traditional Japanese Kigumi joinery techniques. Constructed entirely without nails or screws, the interlocking structure embodies the craftsmanship of master temple carpenters and the wisdom developed through centuries of Japanese architectural tradition. The contrasting colors and grain patterns of the different wood species highlight the natural beauty and individuality of each material. More than decorative objects, the Kigumi Puzzles invite interaction. By observing the structure and discovering how the pieces fit together, users can explore the logic and ingenuity of traditional Japanese joinery. Combining playfulness with exceptional craftsmanship, it offers a hands-on experience of the beauty and complexity of Kigumi construction.
