Here is also very interesting article about Yakuza and Tepco. Possibly it was already posted, but I couldn't find it.
In the case sorry for the double.The Yakuza and the Nuclear Mafia: Nationalization Looms for TEPCO
Tokyo Electric Power Company (TEPCO), the monolithic corporation that controls all electric power in Greater Tokyo, and runs the Fukushima Daichii nuclear plant that experienced a triple meltdown following the March 11 earthquake, is on the brink of nationalization according to Japanese government sources. The official reason is that the firm may not be able to handle the massive compensation payments it owes to victims of the meltdown without going bankrupt. Unofficially, the firm has such long-standing ties to anti-social forces, including the yakuza—that some members of the Diet, Japan’s national legislature, feel the firm is beyond salvation and needs to be taken over and cleaned up. A Japanese Senator with the Liberal Democratic Party stated on background, "TEPCO's involvement with anti-social forces and their inability to filter them out of the work-place is a national security issue. It is one reason that increasingly in the Diet we are talking de facto nationalization of the company. Nuclear energy shouldn't be in the hands of the yakuza. They're gamblers and an intelligent person doesn't want them to have atomic dice to play with."
As someone Japanese on Facebook said: One yakuza explains it as folk wisdom, “Otoko wa Genpatsu, Onna was Seifuzoku･男は原発、女は性風俗”--, in other words, “When a man is has to survive doing something, it’s the nuclear industry; for a woman, it’s the sex industry.”
Why not emigrate and teach your language in other country's?
