70% of Japan is covered in forests. The Japanese have been using wood as a building material for hundreds of years, and the nation is home to the world's oldest wooden structures. Their longevity is a testament to the skill of the people who built them. In the second of two editions focusing on wood, Japanology Plus introduces the tools and techniques used by Japanese carpenters. Our guests are Kenzo Akao, director of the Takenaka Carpentry Tools Museum, and Akinori Abo, a professional carpenter.
