a) only a small part of Japan was affected by a very small amount of radiation. No one has yet died from the radiation. That still leaves a very large rice growing area of Japan to grow rice for your Sake. b) Do Japan even grow all of their rice for their Sake? It's a high population country, I'd be willing to bet they import at least some of the rice for it. c) Japan is not the only rice growing nation in the world... do no other countries make Sake that you could buy?
