Ryusei Maru was a cargo steamship that was built in England in 1911 and sunk off the coast of Bali in 1944. She was launched as Bra-Kar for Fred. Olsen & Co. of Norway. In 1916 she changed owners and was renamed Havø. In 1935 she changed owners again and was renamed Mabuhay II.

MS Aramis was a Messageries Maritimes ocean liner that was launched in France in 1931. She was a sister ship of Félix Roussel and Georges Philippar. The three sisters were highly unusual in having square funnels. Aramis' interior was an Art Deco interpretation of Minoan design.
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.
The Japanese aircraft carrier Taiyō was the lead ship of her class of three escort carriers. She was originally built as Kasuga Maru (春日丸), the last of three Nitta Maru class of passenger-cargo liners built in Japan during the late 1930s for NYK Line. The ship was requisitioned by the Imperial Japanese Navy (IJN) in early 1941 and was converted into an escort carrier. Taiyō was initially used to transport aircraft to distant air bases and for training, but was later used to escort convoys of merchant ships between Japan and Singapore. The ship was torpedoed twice by American submarines with negligible to moderate damage before she was sunk in mid-1944 with heavy loss of life.
Shin'yō Maru was a cargo steamship that was built in 1894, had a fifty-year career under successive British, Australian, Chinese and Greek owners, was captured by Japan in the Second World War, and sunk by a United States Navy submarine in 1944.
SS Heidberg was a cargo steamship that was built in 1943 in Sweden for a German shipping company. The Allies in 1945 took it for war reparations. She was renamed Empire Convention, and spent about nine months under United Kingdom ownership and management. In 1946 she was transferred to the Soviet Union, who renamed her Эрнст Те́льман – Ernst Thälmann. Her fate is not recorded.
SS Waroonga was a steel-hulled passenger and cargo steamship that was launched in Scotland in 1882, renamed Bansei Maru in 1913 and scrapped in Japan in 1926. Her career included periods in British, Australian and Japanese ownership.

She was requisitioned by the Royal Australian Navy in 1914, as a store carrier and collier. She was returned to her owners in 1915. She was sold in 1935 to Machida Shokai Kisen Kaisha, Japan and renamed Seiko Maru, before being sold to Kita Nippon Kisen Kaisha and renamed Siberia Maru No. 3, which was later shortened to Siberian Maru. While steaming in the Sulu Sea, Philippines on 24 September 1944, she was attacked by American aircraft of Task Force 38 and sunk with the loss of 158 of the 2,382 people on board.
The SS China Maru was a 5,870-gross register ton cargo ship built by Kawasaki Dockyard Company, Kobe, for Kawasaki Kisen KK in 1920.
Takao Maru (高雄丸) was an OSK Line cargo and passenger steamship that was built in Japan in 1927. In 1941 the Imperial Japanese Army requisitioned her. US aircraft damaged her during the first week of the Japanese invasion of the Philippines. In 1942 she was declared a total loss.
Compañía de Filipinas was a cargo steamship that was built in Scotland in 1890 for the Compañía General de Tabacos de Filipinas (CGTF). In the Philippine–American War the Navy of the First Philippine Republic armed her as its flagship and renamed her Filipinas. After that war she reverted to her original name and commercial service. In the Second World War, Japanese forces captured her and renamed her Hoei Maru. She was sunk in July 1945, shortly before the end of the war.

She was launched as the turbine steamship War Bamboo, and for most of her career she was called Boswell (1920–34), Germa (1937–51), or Norway Maru (1951–1968/70). She spent only about three years as Adderstone (1934–37). However, it was as Adderstone that the ship was the test-bed for an innovative development in marine steam propulsion, which used reduction gearing not only for an exhaust steam turbine but also for a high-speed reciprocating steam engine.
SS Agios Georgios IV was a Greek-owned cargo steamship that was built in England in 1938 and sunk by a Japanese submarine in the Indian Ocean in 1942. Agios Georgios IV was one of a relatively small number of steamships that had White combination engines. This was a combination of a high-speed four-cylinder compound steam engine that drove the propeller shaft via single-reduction gearing, with an exhaust steam turbine that drove the same shaft via double-reduction gearing.
Nagoya Maru was a Japanese cargo steamship that was built in Nagasaki in 1932. In the Second World War the Imperial Japanese Navy used her first as a submarine depot ship and then to transport aircraft. A United States Navy submarine sank her in 1944.
