It is important, just in the early stage after the outbreak, to collect information in various wide-ranging
fields from the transectional aspect of organization on the basis of the viewpoint of inspection of the cause,
rather than the means of approaching to events. The related information in the past must also be
thoroughly collected, and the information must be presented to the persons concerned.
In the process of inspection of the cause, the information kept by companies and the administration must
be opened to investigators and the victims. For the problems such as environmental ones particularly, to
which interdisciplinary studies are needed, exchange of information among investigators regardless of
special field is essential.
The administration must promote active effort and opening of information to the public by companies
about environment by introducing the PRTR system, etc.

pollution and opening of information to public for the purpose of preventing damages will lead to the
interests of companies themselves from a long-term viewpoint.
