A mediation committee headed by Kumamoto Prefecture Governor Hirosaku Teramoto was formed to hammer out a solution. At a meeting on 2 December the prefectural fishing alliance outlined their demands: compensation of JPY2.5 billion (USD6.9 million) for damage to fishing since 1953, the temporary closure of the factory and removal of toxic sludge. The committee then met company executives, including Chisso president Kiichi Yoshioka, who responded with an offer that amounted to "nearly zero". After weeks of wrangling the fishing alliance reduced its demands to JPY980 million (USD2.7 million) and Chisso, under increasing pressure from all sides, relaxed its position. The proposed agreement (presented with the ultimatum of no further mediation from the committee should it be rejected, as previously) called for the immediate installation of wastewater treatment facilities, JPY35 million compensation to be paid to the alliance (JPY10 million of which would be deducted to cover the damage caused in the 2 November riots) and a JPY65 million fund for the recovery of the fishing industry. The agreement also included a clause that the alliance could never demand further compensation, even if the factory's waste was proven to be the cause of the damage. The agreement was accepted by both sides on 17 December.
