Is japan still in ruins?

Question:

also did they fix the radiation problem?

Answer:

First off, MOST OF JAPAN, the VAST MAJORITY of Japan wasn't destroyed, nor was it affected by the tsunami. The major areas encompass the coastal regions of northeastern Japan, they are still working to rebuild, and it will take years.

The rest of Japan, the vast majority of Japan is fine and operating in an almost normal condition, given the circumstances.
