I just found this report on the current recovery progress in Japan after the recent earthquake/tsunami. It looks like in some facilities, significant work still has to be done. This is discounting the infrastructure issues of the surrounding areas that provides water, electricity, and access/roadways.
The recovery will be very slow. I know of many colleagues who thought they would be busy with work and/or travel to Japan this summer who suddenly find themselves having a wide-open few months due to conference and work cancellations.
