From earthquake-defying joints that support a temple to delicate puzzle boxes, an exhibition shows off the myriad possibilities of the art of Japanese carpentry

Do you know your ant's head from your shell mouth? Or your cogged lap from your scarfed gooseneck? These are just some of the mind-boggling array of timber jointing techniques on display in a new exhibition spotlighting the meticulous craft of Japanese carpentry. The basement gallery of London's Japan House has been transformed into a woody wonder world of chisels and saws, mortises and tenons, and brackets of infinite intricacy, alongside traditional clay plastering, shoji paper screen making and tatami mat weaving. It is a dazzling display of the phenomenal skills behind centuries of timber architecture and joinery, celebrating elite master carpenters with the spiritual reverence of a high priesthood.

"In Japan we have a deep respect for our forests," says curator Nishiyama Marcelo, who heads up the team at the Takenaka Carpentry Tools Museum in Kobe. "If a carpenter uses a 1,000-year-old tree, they must be prepared to take on more than 1,000 years of responsibility for the building that they create."

It is a momentous duty, and one we should heed. As debates around the embodied carbon of the built environment dominate the construction industry, there could be no more timely exhibition to remind us of the importance of designing with longevity, care and repair in mind.

Numerous specialist tools have been shipped over from the Kobe museum, along with a team of master carpenters, who have built a remarkable series of structures in the gallery, replicating parts of buildings that have lasted for hundreds of years in the face of wind, rain, snow and earthquakes.
