TEPCO has been offloading its liabilities from the Fukushima disaster since the very beginning, as I've documented in my published research on the Fukushima disaster. Here is the latest example of TEPCO's socialization of liabilities:
TEPCO to seek gov't assistance in decommissioning Fukushima nuke plant. The Mainichi, July 29, 2016, http://mainichi.jp/english/articles/20160729/p2a/00m/0na/012000c
Tokyo Electric Power Co. (TEPCO) Holdings, Inc. is set to ask the national government for financial assistance in decommissioning the disaster-hit Fukushima No. 1 Nuclear Power Plant, company officials said.
The company will also seek consultations with the government over how it should foot the costs of paying compensation to those affected by the nuclear crisis and decontaminating areas affected by radioactive substances from the power station.
TEPCO Holdings has deemed that it cannot secure enough funds to fully cover these costs through its own efforts alone since the expenses are increasingly likely to surpass its estimates.
