The ripples from the Fukushima nuclear disaster have been felt across the globe, drawing offers of sympathy and support for Japan, provoking debates about nuclear power and its alternatives — even sparking complete rethinks of energy policy.

Germany decided to shut down all its nuclear reactors by 2022 in response to the Fukushima crisis. Switzerland will close its remaining five reactors by 2032, and Italians were voting on whether to abandon nuclear power for good in a referendum over the weekend.

Japan has made no such promise, and the government has been criticized for being slow to react to the disaster. But as the politicians dither, the Nishida family in Tokyo have already made up their minds about the nuclear dangers.
