For this, Yoshiyuki KASAI, chairman of the Central Japan Railway Company (JR Central) refuted in a book he wrote that 'The Shinkansen line was constructed with only internally reserved money and borrowed money, and the cost has been recovered only by the train fares and other charges, and therefore, it is wrong to say that the construction of Shinkansen triggered the bankruptcy of JNR.'
これに対し、東海旅客鉄道の葛西敬之会長は著書の中で「東海道新幹線はあくまで内部留保された資金と借金で建設資金をまかない、それらを運賃・料金収入のみですべて回収したものであり、新幹線建設が国鉄破綻の引き金を引いたという認識は誤りだ」と指摘している。
