In April 2016, Kumamoto was hit by two major magnitude-7 earthquakes. Kumamoto Castle, the city's icon, was severely damaged. However, the damage has unveiled long-lost secrets of the castle's construction. The key parts that withstood the powerful tremors were in fact the castle's oldest sections, built over 400 years ago. Why is this samurai architecture so sturdy? Using a detailed 3D model based on 4K high-resolution drone images, experts study and reveal the secrets of the quake-resistant mega structure.
