Technically true, but would you raise a family there? What would your extended family think? Would friends visit? If not, then that land is pretty much tainted and 40 years is generous - several generations maybe required...
I'm eating produce from Fukushima here in Singapore.
But in general, lots of specialty produce is sold with more specific region information beyond just the country. Especially the Japanese producers are really keen on that.
(For a related, but famous example, have a look at wine, especially Champagne which has to be from the Champagne wine region of France.)
