Minamata Konjyaku

In and around Minamata city at present, only Hyakken Outlet and the seawall barrier at Minamata Eco Park designed to keep organic mercury contained have any signs conveying the history of Minamata disease. A long time has passed since part of Minamata Bay has been reclaimed from the contaminated sewage of Chisso. Very few traces of the evidence of the Minamata disease incidents remain. Knowing and understanding such histories around these areas is indispensable to put the lessons of Minamata disease to good use. We created “Minamata now and then” to let you re-experience the changes in Minamata from the past till now.

In “Minamata Now and Then”, you can see the differences and changes in Minamata through a pictorial display of maps from the late Edo period through to maps from the Meiji era to present. The maps are held by Kumamoto Gakuen University and we have added current and historical photos and related historical information on a map of Minamata. All this helps you trace the local history of Minamata.

The pictures were selected from the approximately 600,000 pictures taken in 1960’s among the old archival documents in the Shin-Nihon Chisso Labor Union. You can identify some images of Minamata city, and see each site in the past and the present as well.
