Experiencing Traditional Japanese Architectural Techniques (1): “Kigumi” What is “Kigumi”? Traditional Japanese Architectural Techniques “Kigumi” is a traditional construction method in Japan that is said to have been used as early as the Heian period. With minimal use of metal fittings such as nails, it is a highly precise technique of building structures primarily using wood. By intricately carving and processing the ends of the timber, they are fitted together tightly to form a sturdy framework. Characteristics of “Kigumi” Despite the minimal use of metal fittings, buildings constructed using “Kigumi” exhibit high durability and seismic resistance. Unlike modern machine-cut timber, “Kigumi” involves hand-carving along the wood fibers. As a result, the wood retains its strength and resilience, making it a highly durable structural material. Furthermore, since it does not rely on nails or bolts for connection, “Kigumi” joints may have slight gaps. These gaps effectively absorb seismic forces during earthquakes, allowing the structure to withstand tremors. “Kigumi” can be considered a technique well-suited to Japan’s earthquake-prone environment. Examples of “Kigumi” Architecture One of the most famous temples in Japan and a UNESCO World Heritage Site, Horyu-ji Temple, is renowned for its construction using “Kigumi.” Maintaining its beautiful appearance
