Cabinet Secretary, Edano Yukio, has told Japanese living outside the current 20km (12.4 miles) evacuation zone, to prepare for mandatory evacuations.

Edano has also told people, that if they wish, they should voluntarily evacuate now.  The concern is that it looks like efforts to get the reactors at Fukushima Daiichi nuclear plant under control, are not working.

Also, advisers from the United States, have told TEPCo officials that the use of salty sea water is doing more damage than good. A U.S. Navy tanker ship with fresh water, is on its way to the nuclear plant.
