Japan constructed a 395-kilometer-long tsunami wall

 

Following the devastating 2011 earthquake and tsunami, Japan constructed a 395-kilometer-long tsunami wall along its northeastern coast. According to PNoy Talks, some sections of the wall reach up to 14.7 meters high and are reinforced with 25-meter-deep foundations, designed to absorb and deflect the force of incoming waves.

As part of a parallel initiative known as the Great Forest Wall, the country planted 9 million trees along the shoreline. According to Anthroposphere, this living barrier was inspired by ecologist Dr. Akira Miyawaki, who envisioned a natural defense system that could slow tsunami waves, trap debris, and restore coastal ecosystems. The trees also help prevent erosion and reconnect communities with nature.

Together, the tsunami wall and forest wall represent a powerful blend of modern engineering and ecological resilience, showing how infrastructure and nature can work hand in hand to protect lives and landscapes.
