Statement by Minamata Victims and Supporter Groups Addressing the Government of Japan’s Proposal to Call the Mercury Treaty the “Minamata Convention”

Minamata disease is an ongoing tragedy. As the global community negotiates the mercury treaty, the Japanese government must first confront the Minamata disease issue at home. After fifty-five years of struggling with the disaster, we are opposed to naming the mercury treaty the “Minamata Convention” until the tragedy is faced head on and a road map created for its genuine resolution. The Government of Japan must make clear what was learned from Minamata, implement the lessons learned and, before the diplomatic conference in 2013, reexamine its policies and make concrete progress toward a genuine
resolution of the elements described below.

The Government of Japan must implement the following with integrity:

1. Clarify the full extent of damage caused by Minamata disease
Although it has been 55 years since the official discovery of Minamata disease, the full
extent of the actual damage is yet to be clarified. Not only is it absolutely necessary to
undertake health studies of the entire contaminated region of the Shiranui Sea, follow up
studies must continue for the residents living in this contaminated area. Recently, research
has shown that children are affected by mercury contamination even at low levels of
exposure. Therefore, it is also necessary to implement studies and measures based on
these findings.

2. Compensate all victims
The Supreme Court verdict of October 2004 established the legal responsibility of the
Government of Japan and Kumamoto prefecture for spreading Minamata disease. The
Osaka District Court verdict found that the criteria established by the Government of Japan in 1977 to certify victims of Minamata disease “had no medical basis.” The Government of Japan must respect these legal decisions and recognize all victims as Minamata disease victims, and, compensate them.

3. Instead of protecting the polluting company, ensure full implementation of the “Polluter Pays Principle”
Under the Minamata Disease Victim Relief Law enacted in July 2009, the polluting
company Chisso Corporation has been allowed to split into two companies, and this
process is moving forward. The polluting company must not be allowed to escape its legal
responsibility. The offender must be made to fulfill its responsibilities as the polluting
4. Clean up the Minamata Bay and Shiranui Sea mercury contamination
Minamata Bay and the Shiranui Sea were contaminated as a result of several hundred tons
of mercury emitted by the Chisso Corporation’s Minamata factory. There are numerous
contaminated areas existing within the city of Minamata. Thorough decontamination of
2 these contaminated areas is essential. Also, the existing landfill of part of Minamata Bay is only a temporary storage area for the toxic methylmercury and cannot be considered final decontamination of the area. It would be a travesty to hold the ceremony for a “Minamata Convention” at the very place where massive mercury contamination is being ignored.

5. Establish a health and welfare system so that victims can live secure lives
within their society
There are so many victims, including congenital Minamata disease victims, who are living
their daily lives in anxiety, worrying about the situation concerning the health and welfare
system in the areas where they live. Monetary compensation alone does not solve the
problems victims encounter. It is absolutely necessary to have a health and welfare system
that victims battling with their own illness and victims continuing to nurse seriously ill
victims can feel secure about.

Implementation of the above is not just an issue for Minamata alone. Beginning with Niigata, Japan, which fell victim to the second Minamata disease, there are innumerable locations around the world contaminated with mercury, and even more in the process of being contaminated. We believe that if the mercury treaty learns the lessons of Minamata, then it will indeed be a treaty of great significance. The tragedy of Minamata was the result of eating fish contaminated with mercury. We the undersigned fervently hope for a strong global treaty, which will significantly decrease mercury contamination worldwide so
that fish are once again safe to eat.
