The idea of building raised stadium-size "islands" to accommodate tsunami-ravaged communities might sound like a bad joke, but that's exactly what one architect is urging devastated towns in Tohoku to consider.

Keiichiro Sako of Sako Architects has formulated a blueprint incorporating groups of such isles that will form entire towns and cities, creating a Utopian world he believes would be strong enough to withstand even the most lethal waves.

Each Tohoku Sky Village, as the man-made communities are dubbed, will be built not in the sea, but on the very land that was engulfed by tsunami last March.
