Had Japan not accepted mail for a while after the earthquake, and are they accepting mail now?

Question:

I have a friend who lives in Kawasaki City. Her mother lived in Fukushima.If you know anything about how these areas are doing, would you please share your information?

Answer:

There is no problem in Kawasaki. Fukushima has Fukushima Plant. So some of residents have been ordered to evacuate. Some areas are still exclusion zone where people are not allowed to enter.

So it depends on where in Fukushima her mother lived.
