Japanese carpentry and joinery requires the use of many types of joints. Nails and glues are believed to not stand up well to fluctuating weather conditions in Japan. Some types of wood are very resinous and therefore glue is not a workable solution. Many structures in Japan, including entire buildings, do not employ a single nail - quite a few of which have stood standing for over 1000 years. This indeed is a good example of Japanese workmanship and attention to detail, long before “quality control” in industrial manufacturing made Japanese quality the world standard.
