Sōryū-class | Aircraft carrier | Sōryū (1937–1942) Hiryū (1939–1942) | 16,200 tonnes | Hiryū is often considered to be a separated class. Sunk at Midway on June 5, 1942 Soryu took part in the attack on Pearl Harbor, the Battle of Wake Island, and supported the conquest of the Dutch East Indies. She was sunk at Midway on June 4, 1942 | |
Shōkaku-class | Aircraft carrier | Shōkaku (1941–1944) Zuikaku (1941–1944) | 25,675 tonnes | With the exception of the Battle of Midway, Shōkaku and Zuikaku participated in every major naval action of the Pacific War, including the attack on Pearl Harbor, the Indian Ocean Raid, the Battle of the Coral Sea, and the Guadalcanal Campaign.

IJN Planned to build 16 ships, however only 3 were completed and 2 almost completed (one of which was sunk as a target then salvaged and later scrapped) before the project was abandoned in favour of Shinano's construction. Unryū was sunk by the USS Redfish, Amagi capsized after air attacks and Katsuragi was the only heavy carrier to survive the war | |
Taihō-class | Aircraft carrier | Taihō (1944–1944) | 30,250 tonnes | A bit of a break from traditional Japanese carrier design, Taiho was a heavily armoured carrier expected to withstand multiple bombs and torpedo strikes.

Shinano-class | Aircraft carrier | Shinano (1944–1944) | 65,800 tonnes | Initially laid down as the third of the Yamato-class battleships, Shinano was converted into an aircraft carrier due to the Japanese defeat at Midway. She was sunk on November 29, 1944, by torpedoes from USS Archerfish. |

The Imperial Japanese Navy was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952 and 1954 after the dissolution of the IJN.
The Akatsuki-class destroyer was a class of four destroyers of the Imperial Japanese Navy. According to most sources, they are regarded as a sub-class of the Fubuki class, partly because the Imperial Japanese Navy itself kept the improvements made a secret, and did not officially designate these four destroyers as a separate class.
Natsushio was the sixth vessel to be commissioned in the 19-vessel Kagerō-class destroyers built for the Imperial Japanese Navy in the late-1930s under the Circle Three Supplementary Naval Expansion Program.
The Minekaze class was a class of fifteen 1st-class destroyers built for the Imperial Japanese Navy. Obsolete by the beginning of the Pacific War, the Minekaze-class ships were then relegated to mostly secondary roles, serving throughout the war as patrol vessels, high speed transports, target control vessels, and as kaiten carriers. Most ultimately were lost to U.S. and British submarines. The basic design of the Minekaze was used for the next three classes of Japanese destroyers, a total of 36 ships.
Ōi (大井) was the fourth of five Kuma-class light cruiser, which served in the Imperial Japanese Navy during World War II. She was named after the Ōi River in Shizuoka prefecture, Japan. Designed as a command vessel for a destroyer squadron, she was converted into a torpedo cruiser with forty torpedo launch tubes in a plan abandoned by the Japanese Navy in 1942. During most of the Pacific War, she was used primarily as a fast troop transport and was sunk by a United States Navy submarine in 1944.
The Asashio-class destroyers were a class of ten destroyers of the Imperial Japanese Navy in service before and during World War II. The overall layout of the class proved successful in service and created a powerful ship that served as the basis for the design of the following two classes of destroyers.
A net laying ship, also known as a net layer, net tender, gate ship or boom defence vessel was a type of naval auxiliary ship.
The Kamikaze-class destroyers were a class of nine destroyers of the Imperial Japanese Navy. Some authors consider the Nokaze, Kamikaze and Mutsuki classes to be extensions of the Minekaze-class destroyers, and the Kamikaze class is sometimes referred to as the "Kiyokaze class" to distinguish it from the earlier World War I-era destroyer class of the same name. Obsolete by the beginning of the Pacific War, the Kamikazes were relegated to mostly secondary roles. Most ultimately were lost to U.S. submarines.
The Momo-class destroyer consisted of four destroyers built for the Imperial Japanese Navy during World War I. As with the previous Kaba class, all were named after trees.
Akashi was a Japanese repair ship, serving during World War II. She was the only specifically designed repair ship operated by the Imperial Japanese Navy. The navy based her design on the US Navy's USS Medusa.
The Sokuten-class minelayer was a class of minelayers of the Imperial Japanese Navy (IJN), serving during and after World War II. The class consists of three subclasses, which this article handles collectively.
The Kamishima class minelayer was a class of minelayers of the Imperial Japanese Navy (IJN), serving during and after World War II. Nine vessels were planned under the Maru Sen Programme; however only one vessel was completed by the end of war.
Minoo (箕面) was a minelayer of the Imperial Japanese Navy, which was in service during the final stages of World War II. She was the lead ship of what was intended to be a two-vessel class, but her sister ship, designated Vessel #1822 was not completed before the end of the war.
Ning Hai was a light cruiser in the Republic of China Navy (ROCN) before World War II and the lead ship of her class. She was sunk in the early days of the Second Sino-Japanese War by aircraft from the Imperial Japanese Navy, and her wreck was raised and repaired by the Japanese, re-entering service with the Japanese Navy in the Pacific War as the escort vessel Ioshima (五百島). She was sunk again in September 1944 by a USN submarine.
The Natsushima-class minelayer was a class of minelayers of the Imperial Japanese Navy (IJN), serving during and after the 1930s through World War II. Their design was based on the Tsubame-class, but with increased armament.
Kaibōkan or coastal defense ship was a type of naval ship used by the Imperial Japanese Navy during World War II for escort duty and coastal defense. The term escort ship was used by the United States Navy to describe this category of Japanese ships.
Katsuriki (勝力) was a minelayer of the Imperial Japanese Navy (IJN) serving during World War I and World War II, the only ship of her class. She was the first purpose-built ocean-minelayer in the Japanese Navy.
The Ōtomari (大泊) was an icebreaker of the Imperial Japanese Navy (IJN) serving during the 1920s through World War II, the only ship of her class. She was the only icebreaker warship in the IJN.
Chihaya (千早) was an unprotected cruiser of the Imperial Japanese Navy. The name Chihaya comes from Chihaya Castle, near Osaka, the site of one of the battles of the Genkō War of 1333.
