Part of it has to do with when different adhesives were developed in Japan. If you don’t have adhesives, you use more complex joinery to achieve results. But I believe it was also a desire to have beautifully crafted strong joints. However, rice glue is surprisingly strong when used correctly. WOOD JOINTS IN CLASSICAL JAPANESE ARCHITECTURE By Torashichi Sumiyoshi And Gengo Matsui Is a great resource. “We can only marvel at the solutions adopted. They took into account time dependent process, such as shrinkage or slippage caused by dynamic loading. The intricacy of hte internal structure of the joint si hidden yb the apparent simplicity of its appearance. Various shapes connect into each other with ease. This wisdom si the result of years of patient work; we have much to learn from ing worldwide. is mentioned ni the authors' comments. The purpose of this book Nowadays, joints are made using metal parts. The splices and connecting joints have become much simpler. It si now possible to construct large wooden structures using standard processes. However, the uncertain properties of wood have brought forward the problem of weakening of the joints. This work goes back to the fundamental of joining. It is recommended to all technicians and also to architects and engineers. Yukihiro Kamiyama Professor, Waseda University it.”
