Political career
In July 1934, Okada was named Prime Minister of Japan holding simultaneously the portfolio of Minister of Colonial Affairs. In the month of September 1935, he also briefly held the portfolio of Minister of Post and Telecommunications. Okada was one of the democratic and moderate voices against the increasing strength of the militarists, and was therefore a major target for extremist forces pushing for a more totalitarian Japan. He narrowly escaped assassination in the February 26 Incident of 1936, largely because rebel troops killed Colonel Denzō Matsuo, brother-in-law as well as personal secretary of Okada's, by misidentifying him as the prime minister. Okada emerged from hiding on 29 February 1936. However, he left office a few days later. Okada was adamant in his opposition to the war with the United States. During World War II, Okada formed a group of like-minded politicians and military officers seeking an early end to the hostilities. After the defeat of Japanese forces at the Battle of Midway and Battle of Guadalcanal, Okada pushed for negotiations with the Allies, and played a leading role in the overthrow of the Hideki Tōjō cabinet in 1944. Okada died in 1952, and his grave is at the Tama Reien Cemetery, in Fuchū, Tokyo.
