    Shinyō Maru (真洋丸?) was the name of at least two merchant vessels in Japanese service during the 20th century. Each had a noteworthy place in the maritime history of the Pacific Ocean at the time and they may also serve as representations both of the course of Japanese-American relations during that century, and in relation to each other, of the course of Japanese history in that era.

    The Shinyo Maru [1911-1936] was an elegant liner on the trans-Pacific service, linking Japan with the West Coast of the United States, via Hawaii. The Shinyo Maru [1941-1944] was a cargo steamer, serving as one of the hell ships of the Second World War, used to transport Allied prisoners of war around the Japanese Empire. The latter ship was in fact both the elder and the longer-lived, having operated under a variety of names during a long career that began as far back as 1894.

    Shinyo Maru (1911-1936)


    The liner Shinyo Maru was built in Nagasaki in 1911 by Mitsubishi Dockyard & Engine Works.[1] Her length was 575 ft. and breadth 63 ft. Her tonnage was 13 426 GRT, with a displacement of 21 650 ('22 000') tons.[2] Her triple screws gave her the very brisk speed of 21 knots.

    She was the third of three new liners built specifically for the trans-Pacific liner route for Toyo Kisen Kaisha Steamship Co. (TKK).[3] Her sister-ships were the SS Tenyo Maru (1908-1933),[4] of 1908, and the Chiyo Maru, of 1909. The career of the Chiyo Maru was sadly curtailed in April 1916, when she ran aground in fog, off Hong Kong, and was damaged beyond repair.[5]

    Toyo Kisen Line was third steamship company to offer a regular trans-Pacific liner schedule, in 1899, after the Pacific Mail Steamship Company (PMSS) and the Occidental and Oriental Steamship Company (O&O). These two great rivals were both US companies and TKK was the first Japanese, Asian and even non-American line to enter the service. The move was a reflection of the modernisation of Japan and its desire to take its place as an equal of the "Western" Great Powers, equal in standards of service and of technological development and in the manner of training and operating. The original three ships were the Nippon Maru, the America Maru and the Hong Kong Maru, but when the three large bespoke liners entered service, the latter two were sold to the Osaka Line (OSK) and relegated to coastal traffic around Japan.[6] In August 1916, the Korea Maru and the Siberia Maru were bought from PMSS, partly to replace the Chiyo Maru. However, the company found it difficult to compete during the slump of the 1920s and was taken over by the larger, if then less prestigious, Nippon Yusen Kaisha (NYK).

    The Shinyo Maru continued, with her sister-ship, for several years under NYK management, before being laid up in 1932. She was finally scrapped in 1936. The Tenyo Maru was likewise laid up in 1930 and scrapped in 1933.

    Five years later, in 1941, the Pacific would become the scene of conflict, rather than commerce, between Japan and the United States and an ancient and undistinguished little steamer would be given the mantle of the great liner. This vessel was not to live up to the reputation of its predecessor.

    Shinyo Maru (1941-1944)


    The cargo-steamer Shinyo Maru was originally named the SS Clan Mackay and was built on the River Clyde for the Clan Line. She sailed with them until sold in 1913 to the Adelaide Steamship Company, which renamed her Ceduna. She was then sold, in 1924, to a company in Shanghai which renamed her Tung Tuck. In 1937, she was renamed Chang Teh, and was sold to Greece later that year. She sailed for her new owners under the name Pananis, until seized by the Japanese at Shanghai in 1941 and renamed Shinyō Maru.


    The Allies intercepted a message about the Shinyō Maru and, thinking it was carrying enemy soldiers, the USS Paddle attacked it on September 7, 1944, off the coast of Mindanao. There were 750 American prisoners of war aboard. Some Japanese guards shot prisoners as they struggled from the holds or were in the water;[7] 688 died when the ship sank, leaving only 82 survivors;[8] 47 of 52 Japanese guards died.[9]

    A December 1944 annotation in US military records indicates an intelligence failure helped contribute to the mistargeting of the Japanese transport ship filled with US POWs by the US submarine. "[A] note was added to the message of September 6 that Fleet Radio Unit Pacific (FRUPAC) interpreted as "SHINYOO MARU (750 troops for Manila via Cebu." In pencil was written: "FRUEF [Fleet Radio Unit Eastern Fleet] (31 Dec '44) gets 750 Ps/W"! FRUPAC misinterpreted this crucial part of the message with fatal consequences."[7]

    On September 7, 2000, 14 survivors gathered at Jacksonville Naval Air Station for the eighth, and final, formal survivors reunion.[10]
