Returned on Tuesday evening. First of all I want to make it clear, though I may have done a lot of surveying, I wasn't there chasing dollars. I went with a small team to assist a company in Japan with no nuclear experience. To say the radiological conditions are challenging (from a US perspective) would be an understatement. Earthquake damage was quite apparent in the north and tremors (6.5 the highest) were also experienced. The Japanese we interacted with were very nice and thankful we were there. If you even consider working in Japan the following tidbits might be helpful, you have to pass a test to drive there or at least rent one. It is used to see if you can read Japanese road sign (I can't). Not a lot of Japanese speak English or hide the fact that they do. Living would not be close to the reactors. Not a commute I would consider.
I'll post some more when I get caught up here.
