According to the sentences of the declaration, 'the Japanese government shall remove all obstacles to the revival and strengthening of democratic tendencies among the Japanese people' and 'Freedom of speech, of religion, and of thought, as well as respect for the fundamental human rights shall be established,' the General Headquarters of the Allied Powers (GHQ/SCAP) led by Douglas MACARTHUR demanded modification of the Constitution of the Empire of Japan.
同宣言には「日本国政府ハ日本国国民ノ間ニ於ケル民主主義的傾向ノ復活強化ニ対スル一切ノ障礙ヲ除去スベシ」「言論、宗教及思想ノ自由並ニ基本的人権ノ尊重ハ確立セラルベシ」等と定められたため、ダグラス・マッカーサー率いる連合国軍最高司令官総司令部（GHQ/SCAP）は、大日本帝国憲法の改正を日本政府に求めた。
