in the brain and attacks the central nervous system, killing brain cells and turning the brain into a sponge, full of holes. Since it destroys nerve cells, there is no cure for severe cases. The poison can kill a victim in weeks, or slowly eat away at the body for years.
Within a year, a pathologist, Dr. Tadao Takeuchi at Kumamoto
University, confirmed the findings, and a special governmental research committee also found that organic mercury was the cause, although it did not attribute the mercury's origins to Chisso's operations. The government disbanded the committee as soon as the report was issued and transferred any further research to a group under the control of several trade minis- ters who were sympathetic to the company. Chisso executives tried to deflect attention away from its wastewater by advancing its own theory that the disease was caused by ammunition dumped in the sea at the end of World War II. A researcher at Kumamoto University, Dr. K. Irukayama, discovered, however, that inorganic mer- cury used as a catalyst in the production of acetaldehyde in the factory was converted into organic mercury. He concluded that the illness was caused by the discharge from Chisso's wastewater, which contained organic mer-
- cury. Chisso disputed the charge and claimed that its wastewater could
not be the cause since it used only harmless inorganic mercury in its pro-
- duction. The company did not share samples of its wastewater, so no one
could disprove the claim. No one, that is, except Chisso's own Dr. Hosokawa. The doctor had been conducting a series of experiments on cats by feeding them food sprinkled with various chemicals from Chisso's processes. When he fed wastewa- ter from the process that produced acetaldehyde to a cat, it exhibited the same symptoms as those afflicted with Minamata Disease. An autopsy of the cat and lab results confirmed that the cat's cerebellum was destroyed, just as the fishermen's were. Hosokawa informed the Chisso management
- f the disturbing discovery. The officials ordered Hosokawa to stop his
experiments, and the company destroyed all the cats. No replication of the experiment was allowed. Not only did Chisso deny that its production wastewater was respon- sible for the disease and suppress Dr. Hosokawa's evidence, the company also steadily increased its production of acetaldehyde and the mercury- laden wastewater. Production in 1950 was 450 tons per month; by 1956 it was 1,325 tons per month; and by 1958 it had increased to 1,500 tons per
- month. When the water in the sea near the point where the wastewater
MINAMATA, JAPAN
13 was diverted into the mouth of the Minamata River, north of the plant.
- Dr. Hosokawa warned Chisso against this diversion, but the company
ignored him. Within a year, the disease emerged in fishing villages north
- f Minamata. Yet Chisso continued to increase the manufacture of acet-
aldehyde with its mercury byproduct, reaching 4,000 tons per month
in 1960. As the disease spread, it became clear that it was related to the con- sumption of fish that had been contaminated with some toxic substance. Fishing catches had decreased by 90 percent since the outbreak of the dis- ease, and what few fish were left in the area were seldom sold. At first the public simply stopped buying it. Later, the local government barred the sale of fish from the area, which only aggravated the fishermen's finan- cial plight. Fishermen began to hold demonstrations to protest Chisso's destruction of their fishing grounds. The patients who suffered from Minamata Disease also began to orga-
- nize. They camped out in front of Chisso's plant and conducted peace-
ful sit-in demonstrations with the help of a tent donated by Chisso union
- workers. The patients demanded financial support from Chisso to pay for
medical and living expenses. Chisso dominated the economy of Minamata, contributing over half of the city's tax revenue and over one-third of the jobs, and most of the local city officials were former Chisso employees. Because of this, most Minamata citizens were unsympathetic and even hostile to the patients. Through the intervention of the local government, Chisso agreed to a two-part settlement. In November 1959 Chisso agreed to pay the fishing cooperative of 7,000 families ¥35 million ($98,000)' as a lump sum compensation, but deducted ¥10 million ($28,000) for damage to its property during one of the demonstrations. Each family ended up with an equivalent sum of about ten dollars. Chisso also provided ¥65 mil- lion (about $180,000) for restoration of the fishing grounds, but this was in the form of a loan to the fishermen's cooperative. Then in December 1959, Chisso agreed to also settle with the patients by offering a take-it-or- leave-it deal: ¥30,000 per year ($83) support for each child, ¥100,000 per year ($276) support for each adult, and a lump sum of ¥300,000 ($833) for each dead person, of which there were about 30. Chisso offered the money only as a mimaikin, or condolence, rather than as a hosokin, or compensation. In Japan, the condolence is offered as a gift to those less fortunate, as a form of charity, in contrast to compensa- tion, which reflects an admission of responsibility for the harm. Moreover,
