context: An arbitration committee was duly set up by the Ministry of Health and Welfare on 25 April, but it took almost a year to draw up a draft compensation plan. A newspaper leak in March 1970 revealed that the committee would ask Chisso to pay only ¥2 million ($5,600) for dead patients and ¥140,000 to ¥200,000 ($390 to $560) per year to surviving patients. The arbitration group were dismayed by the sums on offer. They petitioned the committee, together with patients and supporters of the litigation group, for a fairer deal. The arbitration committee announced their compensation plan on 25 May in a disorderly session at the Ministry of Health and Welfare in Tokyo. Thirteen protesters were arrested. Instead of accepting the agreement as they had promised, the arbitration group asked for increases. The committee was forced to revise its plan and the patients waited inside the ministry building for two days while they did so. The final agreement was signed on 27 May. Payments for deaths ranged from ¥1.7 million to ¥4 million ($4,700 to $11,100), one-time payments from ¥1 million to ¥4.2 million ($2,760 to $11,660) and annual payments between ¥170,000 and ¥380,000 ($470 to $1,100) for surviving patients. On the day of the signing, the Minamata Citizens Council held a protest outside the Minamata factory gates. One of the Chisso trade unions held an eight-hour strike in protest at the poor treatment of the arbitration group by their own company.
