He graduated from the 27th class of the Army Staff College in December 1915. In his early career, he served in the Imperial Japanese Army General Staff Office and at the Army Ministry. From January 1925 to March 1927 he was assigned as a military attaché to Germany. On his return, he again served in various bureaucratic posts involved in military production and resources planning. After his promotion to lieutenant colonel in 1929, he served as chief of the 2nd Section of the Cabinet Planning Board. He was transferred to the staff of the Kwantung Army in April 1932, and was promoted to colonel in August of the same year. After serving as chief of the Mobilization Section, Economic Mobilization Bureau at the Ministry of War in 1933, Yokoyama served as battalion commander of the IJA 2nd Regiment in 1934 and was promoted to the staff of the IJA 6th Division in 1936.
