Viscount Ishii Kikujirō (石井 菊次郎, April 24, 1866 – May 25, 1945), was a Japanese diplomat and cabinet minister in Meiji, Taishō and early Shōwa period Japan.After a term as Japanese ambassador to France from 1912 to 1915, he became Minister for Foreign Affairs under the 2nd Ōkuma administration from 1915 to 1916, playing a major role in the normalization of relations between Japan and Russia.As special envoy to the United States from 1917 to 1918, he negotiated the Lansing–Ishii Agreement, which was intended to defuse tension between the two nations, but was limited in its effectiveness due to the reluctance of either government to make any concessions.Ishii traveled to Europe to take part in the Paris Peace Conference to take the initiative at the demarcation of the German–Polish border, and later served as president of the Council and the Assembly of the League of Nations in 1923 and 1926.During the third firebombing of Tokyo on May 25, 1945, Ishii was last seen heading towards Meiji Shrine, which was the designated safe refuge for his neighborhood association during the bombing.
