<p style="text-align:justify"><strong>A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers from Tokyo Tech. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.</strong></p>
