Tepco and the Japanese government knew that a much larger then anticipated Tsunami could be generated off the NE coast of Japan. New data came out a couple of years prior to the accident. They both ignored the new findings and green lighted these old reactors to run past their scheduled lifetimes. The economy was their primary concern and human safety took a back seat to that. Tepco has been nationalized anyway. It was always just a front for the Japanese government. A corporate fall guy to shield the government from culpability.

Now the Japanese government has restarted its first reactors and they are located over a newly active fault.
