When KAYAMA asked Perry to give him 4 days to talk with his superiors, Perry answered that he would wait three days, and further threatened that if the Shogunate did not dispatch a high ranking officer to whom he could hand the letter, he and his men would sail to the north of Edo Bay and hand the letter directly to the Shogun.
香山は上司と相談する為に4日の猶予をくれるように頼んだが、ペリーは3日なら待とうと答え、さらに親書を受け取れるような高い身分の役人を派遣しなければ、江戸湾を北上して、兵を率いて上陸し、将軍に直接手渡しすると脅しをかけた。
