Painting the Hell Ships: The Left-Handed Legacy of Kihachiro Ueda

During the brutal expanse of the Pacific War, the Imperial Japanese military transported tens of thousands of Allied prisoners of war (POWs) and Asian forced labourers across the ocean aboard requisitioned merchant vessels. Because these ships operated under suffocating, inhumane conditions and frequently fell victim to Allied submarines and aircraft, they became infamous as "hell ships".

Today, historians and the descendants of the POWs rely heavily on written testimonies and a handful of grainy, often combat-obscured reconnaissance photographs to understand the terrifying reality of these floating dungeons. However, a significant portion of the visual record that exists today—vivid, detailed depictions of these specific vessels—survives thanks to the extraordinary dedication and tragic personal history of a single Japanese naval artist: Kihachiro Ueda (上田毅八郎). His left-handed legacy stands as a poignant intersection of military history, personal trauma, and artistic resilience.

To understand the depth of Ueda’s contribution, one must look at his wartime service. During World War II, Kihachiro Ueda served as a soldier in the Japanese army and was specifically assigned to duty aboard Japanese merchant ships. The Japanese merchant fleet was the lifeblood of the empire, tasked with the constant transportation of troops, raw materials, and prisoners across the vast Pacific theatre.

As the war progressed and Allied forces began their reconquest of the Philippines in late 1944, Japanese shipping in Manila Harbor became a prime target for devastating American air raids. On November 14, 1944, Ueda was serving aboard the Japanese merchant vessel Kinka Maru while it was anchored in Manila Harbor.

On that day, the ship came under heavy bombing. During the attack, Ueda was severely wounded, sustaining injuries so catastrophic that he completely lost the use of his right hand. For an artist, the permanent loss of a dominant hand could have meant the end of a creative life, but for Ueda, it became the catalyst for a remarkable post-war mission.

Following his severe injuries and the conclusion of the war, Ueda returned to his home in Hamamatsu City, Japan. Refusing to abandon his art despite his profound physical disability, he painstakingly taught himself how to paint using only his left hand.

Driven by his unique firsthand knowledge of the Japanese merchant marine and a desire to document the vessels that defined the maritime conflict, Ueda embarked on a massive undertaking. He produced a considerable volume of paintings that meticulously catalogued the myriad Japanese merchant vessels and military transports that had been decimated by the war.

Through his efforts, a visual encyclopaedia of the Japanese wartime fleet was resurrected from the ashes of the Pacific conflict. Years later, American POW researchers, such as Jim Erickson, discovered Ueda's excellent left-handed paintings and collaborated with him, alongside Yuji Miwa of the POW Research Network Japan, to bring these vital visual records to the families of Allied survivors.

One of the greatest challenges in visually documenting the hell ships is that many were sunk so suddenly that no distinct, high-quality photographs exist of them in their wartime configurations. To circumvent this, Ueda ingeniously utilized his knowledge of Japanese shipbuilding classes.

Because the Japanese built several classes of ships where all vessels were constructed from the exact same blueprints, Ueda could paint a surviving "sister ship" to accurately represent a lost hell ship. This typological approach provided unparalleled visual accuracy for historians and the families of the victims. For example, to depict Tamahoko Maru—a 6,780-ton Eastern Shore Class freighter that was torpedoed by USS Tang on June 24, 1944, killing 560 POWs—Ueda painted its identical sister ship,  Shunko Maru (alias Syunko Maru). Similarly, to illustrate Tottori Maru, a 6,057-ton Glasgow-built ship that transported survivors from tTamahoko Maru's earlier voyages to Korea and Japan, Ueda painted its sister ship, Tokushima Maru.

Ueda’s portfolio spans the wide variety of vessels requisitioned by the Japanese. He painted the Aki Maru, an 11,409-ton ship completed in 1942 that transported Dutch East Indies officers to Formosa. He captured Nagara Maru and the Naruto Maru, both 7,100-ton freighters capable of 19 knots; Nagara Maru notably carried senior Allied officers, including Generals Wainwright and King, away from the Philippines in August 1942.

To document the Asaka Maru, an Akagi Maru Class freighter that transported 738 British POWs from Singapore to Moji, Ueda provided a detailed painting of its sister ship,  Arima Maru. He also painted the Awa Maru, which survived until early 1945 carrying British, American, and Australian captives.

Perhaps the most emotionally resonant of Ueda's works relate to the infamous December 1944 voyage of Oryoku Maru and the subsequent transports of its survivors. Oryoku Maru left Manila on December 13, 1944, packed with 1,619 POWs, only to be bombed and sunk by aircraft from  USS Hornet in Subic Bay.

Recognizing the profound tragedy of this event, Ueda painted Oryoku Maru and graciously donated the artwork to the Hellships Memorial Foundation , ensuring the victims would not be forgotten. The painting is now displayed at the Bamban WWII Museum in Bamban, Tarlac, Philippines.

Following the destruction of Oryoku Maru, the survivors were transferred to two other vessels: t Enoura Maru and Brazil Maru. Both ships reached Takao, Formosa, where Enoura Maru was bombed on January 9, 1945, killing approximately 350 more men.

To document Enoura Maru—a 6,900-ton Class 2A freighter built for mass production—Ueda painted  Ebara Maru, an identical vessel outfitted as a tanker but sharing the exact same profile. Finally, to show Brazil Maru, the older, 5,870-ton Taifuku Maru #1 class ship that carried the last of the wretched survivors to Moji, Japan, Ueda painted its sister ship, Aden Maru. When Brazil Maru arrived in Japan, only about 425 to 550 of the original 1,619 prisoners were still alive. Ueda's paintings of Ebara Maru and Aden Maru serve as the definitive visual representations of the iron hulls where these men suffered their final, agonizing days.

Kihachiro Ueda’s artistic legacy represents a profound transformation of wartime trauma into historical preservation. A Japanese soldier who lost his dominant hand to the violent ravages of the Pacific War, he did not succumb to bitterness or defeat. Instead, he retrained his body and dedicated his left hand to resurrecting the ghosts of the Japanese merchant fleet. His meticulously researched, beautifully rendered paintings provide an invaluable resource for researchers, historians, and the descendants of the Allied POWs.

Through Ueda's canvases, the abstract horrors of the "hell ships" are given shape, dimension, and reality, ensuring that the vessels—and the immense human tragedies they contained—are forever anchored in the visual memory of World War II.
