Quote from GTS:

The WSJ article say that Tokyo is considering more evacuations not that they are considering evacuating Tokyo.
"The areas under review include one neighborhood each in two cities, and could affect more than 180 families."
As for the ABC article....
What you wrote: "Japan's former prime minister Naoto Kan said evacuations on such a scale will make Japan being unable to function. 30 million people from Tokyo and surrounding areas are to be evacuated as a result of the Fukushima nuclear disaster"
What he said: "Japan's former prime minister Naoto Kan has revealed he contemplated evacuating as many as 30 million people from Tokyo and surrounding areas during the Fukushima nuclear disaster."
