He was a complex figure who served in many different capacities. His career spanned military combat, intelligence gathering, and diplomacy. Later in life, he became a founder of Kyoto Sangyo University. His life reflects the shifting political and military strategies of Japan during the early 20th century.

Iwakuro's military career began with formal training in Nagoya. He graduated from the 30th class of the Imperial Japanese Army Academy in 1918. His first assignment was to the 16th Infantry Regiment in Shibata city. In September 1920, his regiment joined the Siberian Intervention as part of an expeditionary force. During this mission, Iwakuro participated in combat against Bolshevik partisans. He was later transferred to the Taiwan Army of Japan in 1921, where he was based in Taichung.

As he advanced, Iwakuro moved into roles involving high-level planning and secret societies. After graduating from the Army War College in 1926, he joined the Sakura Kai. This was an ultranationalist secret society. In 1932, he was assigned to the Kwantung Army in Manchuria. There, he held several staff positions. He was involved in planning for the independence of Manchukuo. He also worked on the economic development of that region under the management of the Imperial Japanese Army.

Iwakuro also became a significant figure in military intelligence, often referred to as a spymaster. Following the February 26 Incident in 1936, he was recalled to Japan. He served as a member of the court martial for the people involved in that incident. Later, in Army Intelligence, he oversaw several secretive operations. These included wiretapping foreign embassies and intercepting mail. He even worked on the production of counterfeit money for future operations. In 1938, he helped establish the Nakano School to train intelligence and counter-intelligence agents.

Between 1939 and 1941, Iwakuro focused on military procurement and technology. He served as the Chief of Army Affairs Section in the Military Affairs Bureau. During this time, he used the Tripartite Alliance to press Nazi Germany for military technology. He specifically sought advancements in armor and aviation-related technologies. Iwakuro also established a research facility to study new developments like microwaves. He held specific views on Japanese strategy. He opposed war with the Soviet Union, a concept known as Hokushin-ron. Instead, he supported Nanshin-ron, which focused on southern expansion.

In 1941, Iwakuro served in a diplomatic capacity in the United States. He was sent as a military attaché to Washington. This appointment happened despite objections from Foreign Minister Yōsuke Matsuoka. The Army believed Matsuoka lacked sufficient experience in foreign affairs. While in Washington, Iwakuro acted as a close adviser to Ambassador Kichisaburō Nomura. He was involved in important negotiations just before the outbreak of the Pacific War. He was eventually withdrawn in August 1941 when a new cabinet formed under Hideki Tōjō.

During the Pacific War, Iwakuro held several command and staff positions. He commanded the 5th Imperial Guards Regiment. This unit was assigned to Malaya and Singapore under the Southern Expeditionary Army Group. In Singapore, he headed the I Kikan. In this role, he served as a senior liaison officer with the Indian National Army. By 1943, he was promoted to Vice Chief of Staff of the Twenty-Fifth Army. He later served as Chief of Staff of the Twenty-Eighth Army in Burma from 1944 to 1945.

At the end of the war, Iwakuro returned to Japan. In 1945, he was attached to the Army Ordnance Administrative Headquarters. He was also the Head of the Army Investigation Department when the war concluded. His career took a significant turn toward education after the military era ended. In 1965, he became one of the founders of Kyoto Sangyo University. Iwakuro died of a heart attack in 1970. His life remains a notable example of the intersection between military service and academic founding.
