Prince Saionji Kinmochi(西園寺 公望, December 7, 1849 – November 24, 1940) was a Japanese politician, statesman and twice Prime Minister of Japan. His title does not signify the son of an emperor, but the highest rank of Japanese hereditary nobility; he was elevated from marquis to prince in 1920. As the last surviving genrō, he was Japan's most honored statesman of the 1920s and 1930s.
