Sōkichi Takagi

Sōkichi Takagi (高木 惣吉) was a Japanese admiral and political figure opposed to the Tōjō government during World War II. Takagi's efforts to undermine the Japanese wartime government have been compared with the efforts of German Admiral Wilhelm Canaris to undermine the Nazi government, and contributed to the end of the war.

Biography
Takagi was born in what is now part of Hitoyoshi city Kumamoto Prefecture in Kyūshū. He graduated from the 43rd class of the Imperial Japanese Navy Academy in 1915, ranked 27th out of 96 cadets. He served his midshipman duty aboard the cruiser JAPANESE CRUISER Iwate and the battleship JAPANESE BATTLESHIP Aki, and was assigned to JAPANESE CRUISER Chitose and JAPANESE CRUISER Akashi after he was commissioned an ensign.

Takagi attended Navigation School and was promoted to lieutenant in 1921, after which he served as chief navigator on the destroyer JAPANESE DESTROYER Hokaze, submarine tender JAPANESE SUBMARINE TENDER Komahashi and patrol vessel Manshū.

Takagi graduated from Naval War College (Japan) in 1927, upon which he was promoted to lieutenant commander and posted as naval attaché to France until 1930. After his return, he served as private secretary to the Navy Minister for two years before being appointed commander and instructor of the Naval War College from 1933 to 1936.

In 1937, Takagi was promoted to captain becoming Chief of the Navy Ministry's Research Section. While head of the government organization, Takagi often over-stretched the predefined powers of his office, acting as a political contact for the Navy through government officials and statesmen such as Fumimaro Konoe, Kōichi Kido, and Saionji Kinmochi as well as developing contacts with intellectuals within the government.

An opponent of Japan's decision to declare war on the United States, Takagi was removed from his position as Chief of the Research Section in 1942 and was reassigned as chief of staff of the Maizuru Naval District. Promoted to rear admiral on 1 May 1943, in September Takagi (due to his access and unique knowledge of classified files from his time as chief of the Research Section) was asked by Navy Minister Shigetarō Shimada to compile a report analyzing Japanese defeats during the Pacific campaign of 1942. Going far beyond its original purpose, Takagi's analysis of combat evidence, conditions in the Japanese home islands, and air and shipping losses as of that year convinced him that Japan's defeat was inevitable. Believing the only solution for Japan was the elimination of the Tojo-led government and negotiation of a truce with the United States, Takagi was hesitant to present the report to Shimada, instead beginning planning for the assassination of Prime Minister Hideki Tōjō before his removal from office in July 1944.

As a member of the Navy Staff College's Research Department, Takagi was encouraged by the newly appointed Navy Minister Mitsumasa Yonai to compose an ultrasecret document proposing the most favorable scenario for Japan's eventual withdrawal from the Pacific, a project he continued working on in cooperation with other government officials until Japan's surrender in August 1945.

He later worked with Teiji Yabe, a professor of Tokyo Imperial University, on revising the Japanese constitution in October 1945.

Takagi died in 1979 at his home in Chigasaki, Kanagawa, and his grave is at the temple of Tokei-ji in Kamakura.
