Career
After serving in a number of administrative positions with the Imperial Japanese Army General Staff, Inada was assigned as a military attaché to France from 1929-1931. After his promotion to colonel, Inada served as Chief of the 2nd Section (Maneuvers & War Plans), 1st Bureau, of the General Staff from 1938 to 1939, and was thus involved in the planning of the Battle of Wuhan and subsequent operations in the Second Sino-Japanese War.

From 1940 Inada was commanding officer of a heavy artillery regiment based in Acheng in northern Manchukuo. In 1941 he became Vice Chief of Staff of the 5th Army in Manchukuo. He was promoted to major general in 1941, and became Chief of Staff of the 5th Army from 1942.

Inada was then sent as Vice Chief of Staff of the Southern Expeditionary Army Group in the Pacific Theater from 1942 to 1943. To support Japanese forces in New Guinea he was sent in 1943 to command of the 2nd Field Operations Base Area. In 1944 he became commander of the 6th Air Division. Later that year, due to a diplomatic incident in Thailand, he was placed in reserve, then reassigned as commander of the 3rd Shipping Transport Command, based in Singapore. Promoted to lieutenant general in April 1945, Inada was Chief of Staff of the 16th Area Army until the surrender of Japan.

Later life and death
After the end of the war, Inada was arrested by the American occupation authorities and tried before a military tribunal held in Yokohama for war crimes.

He was sentenced to 7 years in prison, and was released from prison in 1951. He died in 1986.
