Gokayama in Japan is marked as a World Cultural Heritage site for its unique nails-free construction technique. No structure in the town utilizes a nail for construction. Not just its dangerous looking mountains and plunging valleys, Gokayama is also known for its World Drama Festival. The multistoried houses here are built on what is referred to as gassho zukuri style, which gained worldwide recognition following UNESCO’s honor. Today, the homes are considered a valuable cultural asset to be passed down from one generation to another.
