As you'd suspect, a lot depends on the situation. There are hundreds of thousands of people living in evacuation centers, places like school gymnasiums. Life for many is uncomfortable, plumbing not adequate, no place to take a shower, etc., only rice balls for food. When the government relief housing gets completed for those with no alternative on where to live, and rebuilding starts for those who can privately, spirits will pick up. That still is quite a ways off however, much still looking for the deceased. Many businesses have been lost as well, some can start up again, others won't be able to. I saw something about a ship builder, his plant a total wipeout, but going through the rubble his computer still appeared intact, was in an upper floor. He nearly wept, saying that all his ship plans were in it, and there was now the good possibility that he could go back to the business again, without the forty years of plans, just no way. One of the luckier ones.
A big if now is the people that have been evacuated from the reactor proximity, also much living in makeshift shelters. They have no idea how the future is going to play out for them, and most have started to live off food drops, as the local produce and seafood is questionable. Many elderly were never relocated, too much risk to their condition by the upheaval. They are living in ghost towns, often pretty much on their own. Kind of a damned if you do and damned if you don't situation.
Though the news is waning on the quake, the poor situation is still very real for many. A lot of uncertainty throughout the country, including in areas far away from the immediate disaster. How this all is going to affect everyone, especially business? It sure is affecting me in a less than desirable way.
