The Great Wall of Japan
After the devastating earthquake and tsunami of 2011, Japan invested billions of dollars in a colossal engineering project: a Great Wall of concrete that stretches over 400 kilometers along the coast. With walls up to 15 meters high in some areas, this mega construction does not aim to completely stop the giant waves but to reduce their force and provide crucial time for populations to evacuate. This ambitious project is a testament to the resilience and commitment of Japan to the safety of its citizens.
