Abstract: Based on the theories of “Trend of the Times” and “Power”, Hara Takasi formed his view of the US after his visit, which had an important impact on his understanding of the JapanUS relations. Based on his understanding of the United States, he pointed out that special emphasis should be placed on the relationship between Japan and the United States in external relations. In response to the deterioration of JapanUS relations following the JapaneseRussian war, Hara Takasi emphasized the need to ease JapanUS relations. He thought that Japanese Manchurian policy must consider the important influence of US. During World War I, he explained his ideas further and emphasized that JapanUS relations should be close and the war between them should be avoided in order to deal with China. The premise of his diplomatic conception of JapanUS coordination was that US should recognize Japans special status and its traditional rights in China, especially the socalled Manchuria rights. This diplomatic conception was the basis of Japans foreign policy during Hara Takasi cabinet and the core of it was Japans national interests.

Key words: Hara Takasi, political thought, view of the US, JapanUS coordination
