The Elephant Kumiki puzzle designed by Hirokichi Yamanaka, is inspired by traditional Japanese joinery techniques. The inspiration comes from ancient Japanese woodworking, where artisans would create complex structures with no need for nails or screws. Modern designers have adapted these principles into animal-shaped puzzles. The term Kumiki (meaning "to join wood together") puzzles have their origins in Japanese woodcraft traditions. These interlocking wooden puzzles were originally used by Japanese carpenters to practice their craft and create structures without nails. The elephant shape in this puzzle adds a playful and animal-themed twist to the traditional Kumiki design. The puzzle is often enjoyed by both kids and adults for its charm and difficulty.
