Minazuki (水無月 , ”June” ) was one of twelve "Mutsuki"-class destroyer s, built for the Imperial Japanese Navy (IJN) during the 1920s.
 During the Pacific War, she participated in the Philippines Campaign in December 1941 and the Dutch East Indies Campaign in early 1942.
 In March, she was assigned to convoy escort duties in and around Malaya and the Dutch East Indies until she was transferred to Rabaul in early 1943 to ferry troops around New Guinea and the Solomon Islands.
The Dutch East Indies Campaign of 1941–42 was the conquest of the Dutch East Indies (present-day Indonesia) by forces from the Empire of Japan in the early days of the Pacific Campaign of World War II.
 Forces from the Allies attempted unsuccessfully to defend the islands.
 The East Indies were targeted by the Japanese for their rich oil resources which would become a vital asset during the war.
 The campaign and subsequent three and a half year Japanese occupation was also a major factor in the end of Dutch colonial rule in the region.
Shōhō (Japanese: 祥鳳, "Auspicious Phoenix" or "Happy Phoenix") was a light aircraft carrier of the Imperial Japanese Navy.
 Originally built as the submarine support ship "Tsurugizaki" in the late 1930s, she was converted before the Pacific War into an aircraft carrier and renamed.
 Completed in early 1942, the ship supported the invasion forces in Operation MO, the invasion of Port Moresby, New Guinea, and was sunk by American carrier aircraft on her first combat operation during the Battle of the Coral Sea on 7 May.
 "Shōhō" was the first Japanese aircraft carrier to be sunk during World War II.
Sōryū (蒼龍 , Sōryū , meaning "Blue (or Green) Dragon") was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the mid-1930s.
 A sister ship, "Hiryū" , was intended to follow "Sōryū", but "Hiryū"' s design was heavily modified and she is often considered to be a separate class.
 "Sōryū"' s aircraft were employed in operations during the Second Sino-Japanese War in the late 1930s and supported the Japanese invasion of French Indochina in mid-1940.
 During the first months of the Pacific War, she took part in the attack on Pearl Harbor, the Battle of Wake Island, and supported the conquest of the Dutch East Indies.
 In February 1942, her aircraft bombed Darwin, Australia, and she continued on to assist in the Dutch East Indies campaign.
 In April, "Sōryū"'s aircraft helped sink two British heavy cruisers and several merchant ships during the Indian Ocean raid.
Ryūjō (Japanese: 龍驤 "Prancing Dragon") was a light aircraft carrier built for the Imperial Japanese Navy (IJN) during the early 1930s.
 Small and lightly built in an attempt to exploit a loophole in the Washington Naval Treaty of 1922, she proved to be top-heavy and only marginally stable and was back in the shipyard for modifications to address those issues within a year of completion.
 With her stability improved, "Ryūjō" returned to service and was employed in operations during the Second Sino-Japanese War.
 During World War II, she provided air support for operations in the Philippines, Malaya, and the Dutch East Indies, where her aircraft participated in the Second Battle of the Java Sea.
 During the Indian Ocean raid in April 1942, the carrier attacked British merchant shipping with both her guns and her aircraft.
 "Ryūjō" next participated in the Battle of the Aleutian Islands in June.
 She was sunk by American carrier aircraft at the Battle of the Eastern Solomons on 24 August 1942.
Hiryū (飛龍 , "Flying Dragon") was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the 1930s.
 The only ship of her class, she was built to a modified "Sōryū" design.
 Her aircraft supported the Japanese invasion of French Indochina in mid-1940.
 During the first month of the Pacific War, she took part in the attack on Pearl Harbor and the Battle of Wake Island.
 The ship supported the conquest of the Dutch East Indies in January 1942.
 The following month, her aircraft bombed Darwin, Australia, and continued to assist in the Dutch East Indies campaign.
 In April, "Hiryū"'s aircraft helped sink two British heavy cruisers and several merchant ships during the Indian Ocean raid.
The Second Carrier Division (第二航空戦隊 , Dai Ni Kōkū sentai, Ni Kōsen ) was an aircraft carrier unit of the Imperial Japanese Navy's First Air Fleet.
 At the beginning of the Pacific Campaign of World War II, the Second Carrier Division consisted of the fleet carriers "Sōryū" and "Hiryū".
 Both carriers were sunk at the Battle of Midway in June 1942 and were replaced by "Jun'yō" and "Ryūjō".
Nagatsuki (長月 , ”September” ) was one of twelve "Mutsuki"-class destroyer s, built for the Imperial Japanese Navy (IJN) during the 1920s.
 During the Pacific War, she participated in the Philippines Campaign in December 1941 and the Dutch East Indies Campaign in early 1942.
 In March, she was assigned to convoy escort duties in and around Malaysia and the Dutch East Indies until she was transferred to Rabaul in early 1943 to ferry troops around New Guinea and the Solomon Islands.
Fumizuki (文月 , ”July” ) was one of twelve "Mutsuki"-class destroyer s, built for the Imperial Japanese Navy (IJN) during the 1920s.
 During the Pacific War, she participated in the Philippines Campaign in December 1941 and the Dutch East Indies Campaign in early 1942.
 In March, she was assigned to convoy escort duties in and around Malaya and the Dutch East Indies until she was transferred to Rabaul in early 1943 to ferry troops around New Guinea and the Solomon Islands.
Akagi (Japanese: 赤城 "Red Castle") was an aircraft carrier built for the Imperial Japanese Navy (IJN), named after Mount Akagi in present-day Gunma Prefecture.
 Though she was laid down as an "Amagi"-class battlecruiser , "Akagi" was converted to an aircraft carrier while still under construction to comply with the terms of the Washington Naval Treaty.
 The ship was rebuilt from 1935 to 1938 with her original three flight decks consolidated into a single enlarged flight deck and an island superstructure.
 The second Japanese aircraft carrier to enter service, and the first large or "fleet" carrier, "Akagi" figured prominently in the development of the IJN's new carrier striking force doctrine that grouped carriers together, concentrating their air power.
 This doctrine enabled Japan to attain its strategic goals during the early stages of the Pacific War from December 1941 until mid-1942.
