Early career

Inoue was a native of Sendai in Miyagi Prefecture, in the Tōhoku region of Japan. He attended the 37th class of the Imperial Japanese Naval Academy, graduating second out of a class of 179 cadets in 1909. As a midshipman, he was assigned to the cruiser Soya on its 1909 cruise from Dairen to Chemulpo, Chinkai, Sasebo and Tsu. He stayed with Soya on its cruise the following year to Manila, Ambon, Townsville, Brisbane, Sydney, Hobart, Melbourne, Fremantle, Batavia, Singapore, Hong Kong, Makung, and Keelung. On his return, he was assigned to the battleship Mikasa, and then the cruiser Kasuga.

Overseas experience

Shortly after his promotion to naval artillery and submarine warfare techniques and was promoted to sub-lieutenant at the end of that year. In 1913, he served on the cruiser Takachiho, followed by the battleship Hiei. He was promoted to lieutenant at the end of 1915, and transferred to the battleship Fusō. Although Fusō participated in operations in World War I against the Imperial German Navy, Inoue was not in any combat situations.

Inoue was given his first command, the dispatch vessel Yodo on 1 December 1917. At the end of 1918, Inoue was appointed military attaché to Switzerland, and ordered by the Navy to learn German. In 1919, he was part of the Japanese diplomatic delegation to the Paris Peace Conference, where this knowledge proved to be useful. In 1920, he was appointed military attaché to France, and was then ordered to learn French. In December 1921, he received a promotion to lieutenant commander, and was permitted to return to Japan.

After serving as executive officer on the Suma in 1923, Inoue enrolled in the Naval Staff College, graduating 3rd in a class of 21 the following year from the 22nd class. On 1 December 1925, he was promoted to commander. Inoue remained in staff positions for the next several years, including an appointment as naval attaché to Italy from 1927–1929, after which he was promoted to captain.

Inoue enjoyed the brief stint as the captain of the battleship Hiei from November 1933 to August 1935.[4]

As admiral

On 15 November 1933, Inoue was given command of Hiei. However, his administrative talents could not be overlooked, and he returned to shore duties after slightly over a year and a half. Inoue was a protégé of Admiral Isoroku Yamamoto, and was strongly opposed to the Tripartite Pact with Fascist Italy and Nazi Germany. Inoue was a leader of the "leftist clique" within the Japanese military, which opposed Japan's increasing trend towards fascism and overseas expansionism.

Promoted to rear admiral on 15 November 1935, Inoue was made vice commander of the IJN 3rd Fleet, which covered the China theater of operations in 1939 and further promoted to vice admiral the same year. As with Yamamoto, he was a strong proponent of naval aviation. Inoue was awarded the Order of the Rising Sun (first class) in 1940.

In 1940, Inoue became commander of the Imperial Japanese Navy Aviation Bureau, and submitted his thesis for a radical restructuring of the Imperial Japanese Navy to Naval Minister Koshirō Oikawa early in 1941. He was highly critical of the Navy's shipbuilding programme, with its emphasis on battleships over aircraft carriers. Inoue was given command of the IJN Fourth Fleet later the same year, based out of Truk. He was thus in command of Japanese naval forces during the Battle of Guam and Battle of Wake Island. He subsequently relocated his headquarters to Rabaul for Operation Mo, intended to occupy Port Moresby. However, after the Japanese defeat at the Battle of the Coral Sea in May 1942, he was relieved of his command in October, and returned to Japan to become commander of the Imperial Japanese Naval Academy. He became Vice Minister of the Navy in the closing stages of World War II, was promoted to full admiral on 15 May 1945, and officially retired on 15 October of the same year.

After the war, Inoue became an English and music teacher to children at his house in Yokosuka. The site of his home is now a public park.

His grave is at Tama Reien Cemetery in Fuchū, Tokyo, Japan.
