In Japan, Repairing Buildings Without a Single Nail

In the past, making and developing metal was too costly for carpenters in Japan. So instead of using nails, carpenters called “miyadaiku” developed unique methods for interlocking pieces of wood together, similar to a giant 3D puzzle. Takahiro Matsumoto has been a miyadaiku carpenter for over 40 years. He runs his company in Kamakura, Japan, where he assesses and repairs damage sustained by the many ancient temples in his city. Using ancient techniques, he ensures that these spiritual structures stay standing for generations to come.
