(Very) Wishful thinking?
The Fukushima accident's handling does reveal severe deficiencies in government of Japan's current corporatist ruling clique.
TEPCO has radioactive water leaking from the CHEAP water tanks that they built at 1,800 millisieverts an hour. That is a lethal dose within 4 hours.
Hundreds of those crappy water tanks can be expected to leak soon. The situation can easily get so bad that workers can't even get around the area without committing suicide.
The culture of TEPCO and Japanese government officials are reflective of Japanese culture. LIE, HIDE, SNEAK, and CHEAT. Even the simple act of asking the international community for help and bringing in international experts was/is too much. Much better to build cheap water tanks to hold radioactive water and then have workers just causally walk by them without much checking until they are walking in lethal doses of radioactive water puddles.
So from their perspective, it's business and life as usual... The fact that they may destroy the entire northeastern part of Japan doesn't seem to bother them much.
If/when a nuclear catastrophe comes, you can expect TEPCO and Japanese government officials to be drinking foreign water, eating foreign food, and having their family members living in Europe or the Americas.
