Shimazaki was a native of Ōita Prefecture and a graduate of the 57th class of the Imperial Japanese Navy Academy in 1929, ranking 31st of 122 cadets. He served his midshipman duty on the cruisers Iwate and Haguro, after which, as a second lieutenant, transferred to the Imperial Japanese Navy Air Service, enrolling in flight training in 1932. By 1934, he was serving as an instructor at Kasumigaura, Ibaraki in torpedo bomber piloting and techniques.[3]

From 1935-1937, he alternated tours of duty as section commander on the aircraft carrier Kaga and ground training. With the start of the Second Sino Japanese War in 1937, his group was deployed to the ground base in Shanghai, where he experienced a number of bombing missions as the war between Japan and China escalated. He was transferred to the carrier Sōryū from March–December 1938, returning to Yokosuka as an instructor. He returned to combat duty on the carrier Akagi from November 1939-November 1940, when he was promoted to lieutenant commander.[4]

In September 1941, Shimazaki was assigned as equipping officer of the new carrier Zuikaku, responsible for forming its new air wing, with himself becoming its commander when the ship was ready for duty.

Shimazaki is best known as the leader of the second wave of the air attack on Pearl Harbor on 7 December 1941.[5] He was piloting a Nakajima B5N2 "Kate" and led the attack group of 54 high-level bombers and 78 dive bombers. For this success he and Mitsuo Fuchida, the leader of the 1st wave of attack, were awarded with an audience with Emperor Shōwa at the Tokyo Imperial Palace on December 25.[6]

Four months later, Shimazaki was again on board Zuikaku and participated in the raid on Trinkomalee on 9 April 1942, during which he led 18 "Kates" and bombed the ground facilities of the port city of the British-ruled Ceylon.[7]

A month later, Shimazaki participated in the Battle of the Coral Sea, where he again scored a notable success when his torpedo bombers crippled the USS Lexington, which later sank. Previously, Lexington had already sunk carrier Shoho.[8] In the morning of 7 May 1942, his attack group took off Zuikaku in search of the US aircraft carriers. Although they did not find the carriers, they found the fleet oiler USS Neosho and its escort destroyer USS Sims instead. Shimazaki immediately ordered his bombers to attack, sinking Sims and heavily damaging Neosho.[9]

In July 1942, Shimazaki was transferred to Kure Naval District. He spent the rest of his career as a ground-based air officer. He was promoted to commander in October 1944.

Shimazaki was killed in action in January 1945, near Taiwan, as a staff officer of the IJN 3rd Air Fleet. He was posthumously promoted two ranks to rear admiral.[10]
