Toyo University professor Mitsuhisa Watanabe, a polemicist on active faults, has fought a long losing battle against Japan's nuclear industrial complex.

His research, ringing the alarm bell about active faults under and near nuclear power plants, has always fallen on deaf ears.

According to Watanabe, nuclear regulators and power companies have a long history of willfully underestimating the danger posed by active faults near a number of reactors.
