The purpose of this work is to furnish the political, diplomatic and economic history of the relations between the United States and Japan from 1897 to 1909. This period was a climax of a warm and close friendship between the two countries It would be no exaggeration to call these two peoples good brothers separated by the Pacific. In the present complicated relations of the two countries, we need to look back upon bygone days and to reconsider our relations . This is my sincere hope in furnishing this small work.
