Q2: What actions are the responsible companies taking to deal with Minamata disease?

A2: They are providing compensation for the patients and undertaking restoration of the polluted environment.

Commentary:
The companies responsible for Minamata disease, Chisso Corp. and Showa Denko K.K., are responsible for providing compensation for the patients, restoration of the polluted environment, and providing compensation for those who became unable to fish due to the pollution (the polluter-pays principle).
In the case of Chisso Corp., as there was a fear that it might become impossible to pay these costs, the national and prefectural governments have provided financial support to the company through the issue of prefectural bonds since 1978.
