Japan’s 395 km Great Tsunami Wall, constructed post-2011 disaster, features sections up to 14.7 meters high with 25-meter deep foundations and reinforced walls to resist powerful waves, serving as a robust engineering safeguard.

Alongside it, the “Great Forest Wall” includes 9 million planted trees along the shore, acting as a living barrier to slow tsunami waves and prevent debris from re-entering the ocean.

This integration of advanced construction and nature-based solutions highlights Japan’s innovative, forward-thinking strategy for disaster prevention, blending technology with environmental resilience.
