Born in Shimane prefecture, Yamaguchi graduated from the 40th class of the Imperial Japanese Naval Academy in 1912, ranked second out of 144 cadets. As a midshipman, he served on the cruiser Soya and battleship Settsu. After his commissioning as an ensign, he was assigned to the cruiser Chikuma and battleship Aki.
By 1918, Yamaguchi had been promoted to lieutenant and was assigned to a navigation unit with the naval squadron escorting Imperial German Navy submarines received by the Japanese government as part of repatriation payments from Germany at the end of World War I. He then traveled to the United States and attended Princeton University from 1921-1923. On his return to Japan the following year, he served on the battleship Nagato for six months, before graduating from the Naval Staff Collage with honors in 1924. Yamaguchi was promoted to lieutenant commander in 1924.
A member of the Imperial Japanese Navy General Staff in 1927, Yamaguchi was promoted commander the next year and later assigned to the Japanese delegation at the London Naval Conference in 1929-1930. On his return to Japan, he was assigned as executive officer on the cruiser Yura.
Promoted to captain in 1932, Yamaguchi was the naval attaché to Washington, DC from 1934-1937. On his return to Japan, he was assigned as captain to the cruiser Isuzu (from 1936-1937), followed by the battleship Ise (from 1937-1938).
Promoted to rear admiral on 15 November 1938, he was Chief of Staff for the IJN 5th Fleet from 1938-1940 until his eventual appointment as commander of the 2nd Carrier Division, consisting of the aircraft carriers Sōryū and Hiryū.
Yamaguchi's carrier force was part of the attack on Pearl Harbor, and subsequently participated in the Indian Ocean Raid. During the Battle of Midway, Yamaguchi sparred with his superior officer, Admiral Chuichi Nagumo, upon a reconnaissance plane discovering an American aircraft carrier (USS Yorktown) near Midway. At the time, the Japanese carriers' planes were armed with bombs. Nagumo wished to switch the armament to torpedoes. Yamaguchi demanded that no time be wasted and that the planes be launched to attack the American carrier with bombs. Nagumo rejected this; shortly afterward, American carrier aircraft destroyed all the Japanese carriers except Yamaguchi's flagship Hiryū. Yamaguchi quickly ordered two successive attacks on Yorktown which crippled it. Shortly afterward, another carrier air strike against Hiryū resulted in hits by aircraft from USS Enterprise. Yamaguchi was killed in action, choosing to go down with the sinking aircraft carrier. Legend has it that he and the captain of Hiryū went down with the stricken carrier while calmly admiring the moon. He was posthumously promoted to the rank of vice admiral.
