This was the first case that Furukawa accepted responsibility for the mining pollution and paid compensation (called 'baishokin,' however, in the contract, it says 'hoshokin' which means the money you give them as they suffer from damage, while 'baishokin' means the money you give them as you hurt them; before that, any monetary provision was not under the name of compensation but either of 'donation,' 'consolatory money 'cooperation money.')
これは、古河側が鉱毒事件で責任を認めて賠償金（契約書上の文言は「補償金」）を支払った最初の出来事である（それ以前の資金提供は常に「寄付金」「見舞金」「協力金」などの名目で、賠償金ではなかった）。
