actually Japan's economy won't be hit nearly as hard, because Japan's largest (and almost only) asset is it's hi-tech industry/ top of the line research and that was largely spared from any damage
after the devastating Kobe quake in '95 Japan's economy recovered very quickly
the "beyond design basis accident" happening in Fukushima right now realistically won't influence Japan's energy politics much (especially not nearly as much as Germany's), as in Japan there is little alternatives to it (the country has no natural resources) and the population is very pro nuclear power
the current situation will surely be blamed on the fact that the affected reactors are 40 years old and they will manage to communicate that this "could never happen in newer reactors"
