Not only has the Japanese government made it a legal offense to enter the evacuation zone around Fukushima Daiichi, they have expanded the zone as well.

Because of high radiation build up, towns outside the original 20km (12.4miles) zone will be evacuated.  The towns are Katsurao, Namie, Iitate and some areas of Kawamata and Minamisoma.  Residents have until the end of May to leave.
