Japan is spending more than $1 billion to resurrect the area around the wrecked Fukushima No. 1 nuclear plant as the country's "Innovation Coast."

The region is trying to capitalize on technology developed in the five years spent cleaning up the worst nuclear disaster since Chernobyl, including Hitachi Ltd. and Toshiba Corp. robots that slither like snakes or cruise through radioactive water like speed boats to investigate the flooded reactors.

Fukushima Prefecture — like Beirut or post-bankruptcy Detroit — is ripe to develop a strong tech community, according to Samhir Vasdev, an innovation consultant at the World Bank.
