Efforts to hand down lessons from the Minamata disease tragedy continue, even as the government tries to effectively draw the curtain on issues concerning the corporate-caused mercury poisonings.

Minamata Forum, a Tokyo-based nonprofit organization, will hold its 100th public seminar Aug. 28 in Tokyo. The series dates back to Jan. 8, 1998.

Over the years numerous lecturers with various backgrounds, including lawyers, journalists, lawmakers and patients of the disease, have talked about their involvement in Minamata-related issues.
