Artificial Islands for a Tsunami-Proof Japan

Keiichiro Sako of Sako Architects has proposed constructing giant, drum-shaped islands on dry land as a means to protect residents of Tohoku from future tsunamis. The elevated disks come equipped with renewable energy sources in case of emergency, and gates that automatically close after a tsunami warning. While one town is already making a move to install an "island", the cost and culture may prove prohibitive for wide-scale implementation. With a price tag of 20 billion yen, and a futuristic look, residents of conservation coastal towns may not appreciate the design.
