From HP: This is the 51-piece Kumiki Puzzle, conceived by the fourth-generation of Yamanaka Kumiki Kobo, Nao Yamanaka. As the name suggests, it is a work made up of 51 wooden pieces. It has a beautiful design with small cubes arranged regularly. It's hard to tell where to start disassembling it, and the puzzle is highly complete, highlighting the fun of Kumiki craftsmanship. This is the "M size," which is about twice as large as the products from the later years of Yamanaka Kumiki. Larger items require more materials and manufacturing techniques, making them rare works with limited production. *This product does not include the package and instruction manual designed by Sori Yanagi. *Due to its age, there may be discoloration, scratches, and dents. Yamanaka Kumiki Yamanaka Kumiki Kobo's Kumiki puzzles were made as traditional crafts in Hakone until recent years. Production was mostly for export to the United States before and after the war, but it was discovered by Bruno Munari, Taro Okamoto, and Sori Yanagi, and became highly regarded as a traditional Japanese craft both domestically and internationally. Currently, the production of Kumiki puzzles has ended, making them difficult to obtain. Yamanaka Kumiki Kobo The history began with the first generation, Tsunejiro Yamanaka (1874-1954), a sashimono craftsman, who expressed everyday objects using Kumiki. The second generation, Waichi Yamanaka (1902-1943), created Kumiki based on historical buildings and sports competitions. The third generation, Hirokichi Yamanaka (1905-1980), designed Kumiki with various animal motifs, such as the elephant, which is famous for winning the Good Design Award. And the fourth generation, Nao Yamanaka (1936-), changed the focus from the previous ones and poured his passion into creating new Kumiki that showcased the structural aspects of abstract Kumiki. His works attracted attention in the fields of engineering and design, and widely made the existence of Kumiki known both domestically and internationally.
