who made the most money from tsunami disaster?

I heard the interesting article about the earthquake happened 5months ago.

guess who made the　most money after tsunami?

Yakuza did!

when i knew this answer, i thought they must have collect money or made some illegal contract..

i was wrong, 

they worked at the nuclear plant!
i assume they did all the construction work which nobody wanna do.
then charged so　much..

i think they did a good job

but sorry for lower rank yakuza, they must obey whateva boss said.

hmmmm good n bad hey
