Minamata was even dubbed as Chisso's "castle town", in reference to the capital cities of feudal lords who ruled Japan from the 16th to 19th century.
The staple food of victims was invariably fish and shellfish from Minamata Bay and that the cats in the local area, who tended to eat scraps from the family table, had died with symptoms similar to those now discovered in humans.
During the investigation by researchers at Kumamoto University, the causal substance had been identified as a heavy metal and it was widely presumed that the Chisso plant was the source of the contamination.
