  It’s worth noting that the demountable nature of Japanese timberframe joinery extends to the original construction workflow.  The original joinery work happens at the carpenter’s workshop, and only the assembly happens on site.  So in some sense, what Iwakuni’s team is doing is an extension of that original workflow, they’re taking the building timbers from another structure rather than from their workshop.

  
  

  Amazingly, these buildings basically just go right together at assembly time, possibly with the help of some BIG mallets. Professional carpentry teams don't really fiddle with the fit of the joints, rework them on-site, etc., as furniture makers often do. And a tight fit is important as it’s key to the structural qualities of these buildings: rigid enough to stay standing over the long-haul, but flexible enough to handle shear loads from winds, earthquakes, etc.
