About Minamata Disease Archives

Overview of our facility

The Minamata Disease Archives opened in June 2001 at Manabi-no-Oka (Hill of Learning) in Eco Park Minamata, as an establishment affiliated with the National Institute for Minamata Disease of the Ministry of the Environment.
The Archives is a facility with a variety of functions, including: 1) collecting, storing and organizing in a centralized fashion documentary materials and data on Minamata disease and supplying them broadly, as well as conducting research on Minamata disease; 2) supplying information broadly to researchers and the general public through exhibitions and information networks and; 3) organizing conferences aimed at holding academic exchange and other occasions that are related to Minamata disease.
On the merits of being a facility affiliated with the National Institute for Minamata Disease, which is a research institute, the Archives has furnished its exhibition rooms with means for visitors to learn various facts about mercury, the substance that caused Minamata disease, including types and properties of mercury that exist in nature and the circulation of mercury, in addition to learning about Minamata disease. Also on display are the results of measurements, updated constantly, of the mercury concentration taken of the seawater and in the atmosphere of Minamata Bay. Other information being presented in the Archives includes findings from research conducted by the National Institute for Minamata Disease, as well as information on international cooperation activities for mercury pollution issues around the world and on the Minamata Convention on Mercury.
The goal we are trying to achieve through these activities is to advance a further understanding of Minamata disease, to pass on lessons from Minamata disease and to contribute to the development of research on Minamata disease and mercury.

The beautifully shining water surface that brightens us.
Minamata is rich in nature.
Sky, lush greenery, and the sea.
We expressed the landscape of Minamata with water surfaces.
We know the preciousness of nature.
It serves as a place to convey that preciousness.
With these thoughts of ours, we combined the natural water surface with the exterior of the Minamata Disease Archives.
