10 cities around the Fukushima Daiichi nuclear power plant were supposed to get evacuation orders immediately after the nuclear disaster, following the 11 March 2011 natural disasters. Only four of those cities got the evacuation order.
The national government of Japan, and the prefectural government of Fukushima have apologized for the break down in communication.
Also, Tokyo Electric Power Company was responsible for notifying five nearby cities/towns of the nuclear disaster, but evidence shows that was a major ‘F’ up. One town got 80 faxes of the notification, while another town got zero notification!
This major breakdown in communication, by TEPCo and government, resulted in massive confusion about what people were supposed to do.
