Joint profile
San Mai Hozo 三枚ほぞ
A three-piece mitred dovetail that unifies legs and top into one rigid structure without glue or metal.
Assembly insights
San Mai Hozo functions like an inlaid mitred dovetail, typically half an inch thick. The three-piece geometry creates such a rigid connection that table legs and top become structurally unified. The joint exemplifies traditional Japanese joinery at its finest—so effective that structures could theoretically be assembled at large scale using this technique alone. Mastery demands precise layout and careful chisel work.
