Born in Saga prefecture, Hyakutake graduated as an infantry officer from the 21st class of the Imperial Japanese Army Academy in 1909. Noted generals Kanji Ishiwara and Jo Iimura were among his classmates, as was future Chinese leader Chiang Kai-shek. He attended the 33rd class of the Army Staff College in 1921, where he studied cryptanalysis, and was assigned to the Imperial Japanese Army General Staff after graduation.
From 1925 to 1927, as a lieutenant colonel, Hyakutake served as the Japanese Resident Officer in Poland. In 1928 he was assigned to the Headquarters of the Kwantung Army in China. As a colonel he worked at the Army's signal school in 1932 then as a section chief in the General Staff until 1935. After commanding the IJA 78th Infantry Regiment for one year, he took over as Superintendent of the Hiroshima Military Preparatory School in April 1936 and was promoted to major general in March 1937.
In August, 1937 Hyakutake became Superintendent of the Signal School. In March, 1939 he took command of the 4th Independent Mixed Brigade and was promoted to lieutenant general in August of the same year. From February 1940 until April 1941 he was commander of the IJA 18th Division.
World War IIEdit
In May 1942 Hyakutake was assigned command of the IJA 17th Army, headquartered at Rabaul in the Southwest Pacific. His command was subsequently involved in the New Guinea, Guadalcanal, and Solomon Islands campaigns. After the Japanese Eighth Area Army under General Hitoshi Imamura took over operations in the theater, Hyakutake directed Japanese army units solely in the Solomons, primarily on Bougainville. He and his forces were trapped on Bougainville when the Allies established a heavily fortified perimeter at Cape Torokina, and Hyakutake was cut off from reinforcements and re-supply. His attacks on the perimeter failed, and his army was forced to live off the land, hiding in jungle caves for most of the rest of the war.
Hyakutake suffered a debilitating stroke and was relieved of his duties in February 1945 by General Masatane Kanda. There was no way to evacuate him to Japan for medical treatment until February 1946, after the surrender of Japan. He died on 10 March 1947.
