When will Japan regain its former glory?

I used to love Japan, but now it is wreck and horror all around. I so wished to visit Japan, but now what is there to visit but rubble and despair? I have such a strong sympathy for Japan, and know that such a question seems so selfish at such a time, but when will I be able to visit Japan again as a tourist and not just view rubble and despair left over from the earthquake.?
