Fubuki was the lead ship of twenty-four Fubuki-class destroyers, built for the Imperial Japanese Navy following World War I. When introduced into service, these ships were the most powerful destroyers in the world. They served as first-line destroyers through the 1930s, and remained formidable weapons systems well into the Pacific War. Fubuki was a veteran of many of the major battles of the first year of the war, and was sunk in Ironbottom Sound during the Battle of Cape Esperance in World War II.
Kumano (熊野) was one of four Mogami class of heavy cruisers in the Imperial Japanese Navy, serving in World War II. She was named after the Kumano River Kii Peninsula on the island of Honshu in central Japan. The Mogami-class ships were constructed as "light cruisers" with five triple 6.1-inch dual purpose guns. They were exceptionally large for light cruisers, and the barbettes for the main battery were designed for quick refitting with twin 8-inch guns. In 1937 all four ships were "converted" to heavy cruisers in this fashion. Kumano served in numerous combat engagements in the Pacific War, until she was eventually sunk by carrier aircraft from Task Force 38 while she was undergoing repairs at Santa Cruz, Zambales, Philippines in November, 1944.
Yura (由良) was the fourth of the six ships completed in the Nagara class of light cruisers for the Imperial Japanese Navy (IJN), and like other vessels of her class, she was intended for use as the flagship of a destroyer flotilla. She was named after the Yura River near Kyoto, Japan. She served in the early stages of World War II, and was the first Japanese light cruiser to be lost in that conflict.
Kinu (鬼怒) was the fifth of the six ships completed Nagara-class light cruiser in the Imperial Japanese Navy, named after the Kinu River in Tochigi prefecture Japan. She was active in World War II in various campaigns in Malaya, the Dutch East Indies and New Guinea before being sunk by United States Navy carrier-based aircraft in the Philippines in 1944.
The Battle of Borneo was a successful campaign by Japanese Imperial forces for control of Borneo island and concentrated mainly on the subjugation of the Raj of Sarawak, Brunei, North Borneo, and the western part of Kalimantan that was part of the Dutch East Indies. The Japanese main unit for this mission was the 35th Infantry Brigade led by Major-General Kiyotake Kawaguchi.
The Taiyō-class escort carrier was a group of three escort carriers used by the Imperial Japanese Navy (IJN) during World War II. Two of the ships were built as cargo liners in the late 1930s and subsequently taken over by the IJN and converted into escort carriers, while the third ship was converted while still under construction. The first ship converted, Taiyō, ferried aircraft and supplies to Japanese possessions before the start of the Pacific War in December 1941 and also served as a training ship between transport missions. Once the war began she did much the same for the newly-conquered areas. Her sister ship, Un'yō did much the same in 1942. Chuyō, the last of the three to be converted, only ferried aircraft between Japan and the naval base at Truk before she was sunk by an American submarine in December 1943. Her sisters sometimes had other destinations other than Truk in 1943, but it was also their primary destination until they were damaged by American submarines in late 1943 or early 1944. After finishing their repairs in 1944, the sisters combined convoy escort duties with their transport missions and often ventured as far south as Singapore. Taiyō was the first of the pair to be sunk, torpedoed by an American submarine in August, with Un'yō following her sister a month later.
Un'yō was a Taiyō-class escort carrier originally built as Yawata Maru (八幡丸), one of three Nitta Maru-class cargo liners built in Japan during the late 1930s. She was transferred to the Imperial Japanese Navy (IJN) during the Pacific War, renamed, and was converted into an escort carrier in 1942. The ship spent most of her service ferrying aircraft, cargo and passengers to various bases in the Pacific. Un'yō was badly damaged by an American submarine in early 1944. After repairs were completed in June, the ship resumed transporting aircraft and cargo. During a return voyage from Singapore in September, she was sunk by the submarine USS Barb.
Atago Maru was a merchant ship built prior to World War II in Glasgow in 1924 by Lithgows & Sons for Nippon Yusen. One of the first diesel-engined cargo ships in service in Japan, Atago Maru was converted to an oil tanker in 1942. Returning to service in 1943, the ship saw extensive service traveling in convoys during World War II. On 28 November 1944, the vessel was bombed by a United States Army Air Forces bomber while at anchor off Borneo. The shipwreck is a popular diving site in Malaysia.
The Tokai Maru was a Japanese passenger-cargo ship built by the Mitsubishi Heavy Industries shipyard that was sunk in Apra Harbor, Guam, in 1943, during World War II. It had served as a fast ship service between New York City and Japan for Osaka Shosen Co. before World War II; during the war it was used as a military transport ship for the Imperial Japanese Navy.
Hawaii Maru was a 9,482-ton Japanese troop transport during World War II, which sank on 2 December 1944 with great loss of life.
Akagi Maru was one of three Akagi Maru-class armed merchantmen of the Imperial Japanese Navy, and was launched in 1936. Akagi Maru was used initially used as a refrigerated cargo/passenger ship between ports in Japan, Europe and South America. The ship took part in World War II in the Pacific Ocean and was sunk with great loss of life by air attack on 17 February 1944 in Chuuk Lagoon as a part of the Allied Operation Hailstone.
Nissan Maru was a Japanese cargo ship completed in 1939 owned by Nissan Kisen K.K. that was requestioned for service as an auxiliary collier and oiler by the Imperial Japanese Navy during World War II. She served with the 5th Fleet and was sunk by United States Army Air Forces bombers during the Japanese occupation of Kiska in the Aleutian Islands Campaign.
Kaimei Maru was a Japanese troop transport ship operated by the Imperial Japanese Army during World War II which was sunk off Honshu on 4 September 1942 by the American submarine USS Guardfish. The ship was a British WWI Type B military cargo ship built by the Hong Kong and Whampoa Dock Company.
Yamafuku Maru was an auxiliary transport ship of the Imperial Japanese Navy during World War II. She served primarily as a troop transport and cargo ship during the war.
Hokkai Maru was a Kinai Maru-class auxiliary transport of the Imperial Japanese Navy during World War II. She participated in the Japanese occupation of British Borneo and was part of ill-fated convoy HI-71.
