At Tōō Gijuku he studied under the American missionary John Ing and became a Christian. In 1877 he traveled with Sutemi Chinda to Indiana Asbury University, later DePauw, graduating in 1881. Satō and Chinda remained close; Chinda married Satō’s sister.","Satō’s diplomatic career took him to Washington and London and into the Foreign Ministry’s communications and translation work. He assisted Foreign Minister Munemitsu Mutsu during the Sino-Japanese War and served with the Japanese delegation at the Portsmouth peace negotiations in 1905. His career also included representation in the Netherlands and Austria.","As ambassador in Washington during the First World War, Satō participated in negotiations over American steel exports and Japanese shipping. A November 1917 memorandum by Secretary of State Robert Lansing records discussion of the terms Satō had raised with the War Trade Board: Japanese tonnage was sought in exchange for steel.","Satō retired from diplomatic service in 1918. He had adopted Naotake Satō, who also became a senior diplomat, in 1902.
