Looking specifically at the Ansei Edo Earthquake of 1855, Gregory Smits bases much his discussion around the theory that the quake, which struck during a year of special religious significance, was not supposed to have happened. A significant number of Japanese viewed it as "a medicine to correct an imbalanced society."

As crazy as that may sound, then-Tokyo Gov. Shintaro Ishihara's comments after the 3/11 quake and tsunami suggest that some still think along such lines.
