I guess there will be another version of "Pripyat" in Japan now, after the Fukushima disaster...

Not sure if there was a city for the power plant workers there, similar to Pripyat, but no doubt they will close off certain areas that are contaminated...
I do not regret not visiting that city when I travelled past. I still think it is creepy and very tragic. Not my idea of a nice place to visit while on holiday!

Not far from Chernobyl is a fairly large and very pleasant city called Gomel, which is on the Belarussian side of the border. There is virtually no tourism there at all, despite the city being very nice indeed and having interesting tourist attractions and a very long history. Some people there were affected by Chernobyl, but you wouldn't think so from looking at the city itself which was newly renovated.
I recommend visiting there instead of Pripyat!
