Tatsuta Maru

In 1943, Tatsuta Maru became one of the early Japanese Hellship voyages carrying Allied prisoners of war from Hong Kong to Japan. Originally a Japanese ocean liner, the ship had been taken into wartime service and was used in January 1943 to transport about 1,180 men, including 663 Canadian POWs from Sham Shui Po camp, to Nagasaki. The prisoners endured extreme overcrowding, heat, dysentery, and filthy conditions during the voyage. After unloading the POWs in Japan, Tatsuta Maru returned to military transport duty and was later sunk on 8 February 1943 by the American submarine USS Tarpon south of Tokyo. Because the POWs had already been disembarked, the final sinking itself was not a POW-casualty disaster, but the January 1943 voyage remains an important Hellship episode in the history of Canadian and Hong Kong prisoners.

The Ship

Tatsuta Maru was a Japanese ocean liner operated by Nippon Yusen Kaisha (NYK) before the war. In 1941 it was requisitioned for Japanese military use. During 1942 it briefly served in diplomatic exchange and repatriation voyages, carrying Allied and Japanese civilians under protected arrangements, before being returned to normal wartime transport duty. By late 1942 and early 1943, it had become part of Japan’s broader military shipping system, including the movement of Allied POWs.

The Voyage

Publicly accessible voyage records show that Tatsuta Maru arrived at Hong Kong on 18 January 1943 and departed on 19 January 1943 with 1,180 men aboard, including 663 Canadian prisoners of war from Sham Shui Po. The ship reached Nagasaki on 22 January 1943, where the Canadian POWs were disembarked for transfer to labor camps in Japan. Survivor testimony from Canadian POW William Bell describes the voyage as a classic Hellship ordeal: the prisoners were packed so tightly into the hold that there was little air to breathe, many became seasick, dysentery spread rapidly, and the men had to lie in vomit and excrement for much of the trip.

The Attack or Loss

Unlike ships such as Rakuyō Maru, Lisbon Maru, or Oryoku Maru, Tatsuta Maru was not sunk while carrying those POWs. After the prisoners had already been unloaded in Japan, the ship continued in transport service. On 8 February 1943, Tatsuta Maru departed Yokosuka escorted by the destroyer Yamagumo and was torpedoed by USS Tarpon east-southeast of Mikura Jima in the Izu Islands. The ship sank that night with heavy loss of life among its passengers and crew. The open-access voyage record available here does not indicate Allied POWs aboard at the time of sinking.

Casualties and Survivors

For Hellship research, the most important distinction is between the January 1943 POW transport voyage and the ship’s February 1943 sinking. The voyage from Hong Kong to Nagasaki carried 663 Canadian POWs, who survived the crossing and were landed in Japan. The later sinking on 8 February 1943 killed 1,223 passengers and 198 crew, according to the public voyage record, but those losses are not presented in the accessible sources as a POW-casualty event tied to the Hong Kong draft. For that reason, Tatsuta Maru should be included on a Hellships site as an important POW transport vessel, while clearly noting that its final sinking was a separate event.

Legacy and Memorialization

Tatsuta Maru is important in Hellship history because it represents one of the earliest major transfers of Hong Kong POWs to the Japanese home islands. For many Canadian prisoners, it marked the beginning of years of forced labor in Japan after the fall of Hong Kong. Survivor accounts show that even when a Hellship voyage did not end in sinking, the transport itself could still be a deeply traumatic and degrading ordeal. In that sense, Tatsuta Maru helps illustrate a broader truth of Hellship history: the horror lay not only in torpedoes and bombings, but also in the overcrowding, disease, thirst, and filth endured by prisoners while still alive below decks.
