Hōfuku Maru

Hōfuku Maru was a Japanese passenger-cargo vessel requisitioned for wartime transport service. By late 1944 it had become part of Japan’s prisoner transport system, moving Allied POWs through dangerous shipping routes under growing American air and submarine attack. Like other vessels later remembered as Hellships, it was not marked to indicate the presence of POWs, despite carrying captive personnel through active war zones. Its loss in Manila Bay made it one of the significant Hellship tragedies connected to the Philippines.

Hōfuku Maru became one of the major Hellship disasters involving British and Dutch prisoners of war in the South China Sea. A Japanese passenger-cargo ship used as a POW transport, it sailed from Singapore in September 1944 carrying Allied prisoners bound north toward Japan. On 21 September 1944, while at anchor in Manila Bay, the unmarked ship was attacked during an American carrier air strike on Japanese shipping. Because the ship was not marked to show that prisoners were aboard, the attacking aircraft had no way of knowing Allied POWs were inside. The bombing and sinking killed a very large number of prisoners, while only a smaller group of British and Dutch survivors reached shore or were rescued and sent on to captivity elsewhere. The Ship

Ship History

Before its association with immense human suffering, the Hofuku Maru began its life as a commercial freighter. Operating within Japan’s busy inter-island trade network, it was a familiar vessel in East Asian ports and frequently crossed the Pacific, hauling lumber, ore, and other products to Washington, Oregon, California, Canada, England, and Australia. Its early decades gave no indication of its dark future. In October 1941, as Japan militarized, the ship was requisitioned by the Imperial Japanese Army (given Army No. 524) from its commercial owner, Kokusai Kisen K.K.. Initially utilized to transport troops, military cargo, and laborers, its role shifted dramatically by mid-1944. As Allied forces constricted Japan's sea lanes, vessels like the Hofuku Maru were increasingly pressed into service to relocate Allied prisoners of war (POWs). Crucially, the ship was never refitted for human transport. Prisoners were forced into deep, unventilated cargo holds devoid of sanitary facilities, enduring systemic neglect that defined the "Hell Ship" experience.

The Voyage

The civilized standards that governed the ship's post-WWI mission evaporated completely with the outbreak of the Pacific War. In October 1941, the Imperial Japanese Army requisitioned the Hohuku Maru to support its rapidly expanding war machine. The Japanese military repurposed civilian merchant vessels into floating prisons, known colloquially by the Allies as "hell ships," to relocate captured Allied prisoners of war to perform forced labor. The conditions forced upon the prisoners on these ships were universally abhorrent, characterized by a lack of air, food, and water, leading to terminal dehydration, hyperthermia, starvation, and rampant disease.

The ultimate tragedy of the Hofuku Maru began during its final mission in the summer of 1944. The ship was assigned to convoy SHIMI-05, a fleet of ten ships tasked with sailing from Singapore to Miri, Borneo. The convoy was heavily laden with human cargo; five of the ships carried a staggering total of 5,000 POWs, all of whom were subjected to appalling, inhumane conditions.

Upon reaching Borneo, the Hofuku Maru suffered severe engine problems and was forced to separate from the main convoy. Limping onward, the ship sailed to the Philippines, arriving in Manila on July 19, 1944. What followed was an agonizing, prolonged nightmare. The Hofuku Maru remained stranded in Manila for two months—from mid-July until mid-September—while its engines underwent repairs. During this entire layover, the Japanese captors refused to disembark the prisoners. Kept in the sweltering holds of the ship under the brutal Philippine summer sun, the POWs suffered terribly from disease, agonizing hunger, and extreme thirst

Timeline of the Hofuku Maru (1918–1944)

I. Construction and Early Career (1918–1940)

August 6, 1918: The ship is laid down at the Kawasaki Dockyard Company in Kobe, Japan, under the initial designation Taifuku Maru No. 31.
November 1, 1918: The vessel is launched as the Hofuku Maru. It is completed later that year as a Dai-ichi Taifuku Maru-class cargo ship.
February 1920: In a significant post-WWI mission, the ship successfully repatriates German prisoners of war from Japan back to Wilhelmshaven, Germany. These prisoners had been held since the 1914 Siege of Tsingtao.
1928: The ship is sold to the K Line (Kawasaki Kisen Kaisha), operating as a cargo vessel on various Pacific Ocean routes.
1937: The vessel’s name is officially updated/standardized to Hohuku Maru.
1938: The ship is sold to Kokusai Kisen K.K., continuing its service as a commercial freighter.

II. World War II Service and Requisition (1941–1944)

October 1941: The Imperial Japanese Army requisitions the ship. It eventually becomes part of the fleet known as "hell ships," used to transport Allied prisoners of war (POWs) for forced labor.
Summer 1944: Hofuku Maru departs Singapore for Miri, Borneo, as part of Convoy SHIMI-05. It carries 1,289 British and Dutch POWs.
July 1944: Upon reaching Borneo, the ship suffers severe engine failures and is forced to leave the convoy for repairs.
July 19, 1944: The crippled vessel limps into Manila, Philippines.
July – September 1944: The ship remains stranded in Manila for two months for engine repairs. During this period, the POWs are kept in the holds under horrific conditions, resulting in rampant disease, hunger, and dehydration.

III. The Final Voyage and Sinking (September 1944)

September 20, 1944: Repairs are completed. Hofuku Maru joins ten other vessels to form Convoy MATA-27, departing Manila for Japan.
September 21, 1944: Approximately 80 miles north of Corregidor, the convoy is intercepted and attacked by over 100 American carrier aircraft.
The Sinking: All eleven ships in the convoy, including the Hofuku Maru, are sunk.
Casualties:
- 1,047 POWs perish in the sinking or from exhaustion in the water.
- 242 POWs manage to swim to the Philippine shore.
- 42 POWs are rescued by Japanese kaibokans (escort ships).

The Attack or Loss

September 21, 1944, marked the first day that American planes were seen in the skies over Luzon since 1942, bringing tears of joy to POWs working in mainland camps. For the men aboard the unmarked Hofuku Maru, however, the arriving aircraft brought devastation. Unaware that the cargo ship carried Allied prisoners, American aircraft from U.S. Task Force 38.2 (launched from the carrier USS Bunker Hill) spotted Convoy MATA-27. At 10:25 AM, the convoy escorts sighted approximately 40 American aircraft, and anti-aircraft combat commenced. By 10:32 AM, the planes began their bombing and torpedo runs. Hofuku Maru suffered a direct hit to the stern from a 1,000-pound bomb dropped by an SB2C Helldiver aircraft. Minutes later, at 10:35 AM, the vessel was struck amidships by a torpedo. The catastrophic damage caused the ship to break in two, and it sank incredibly rapidly, slipping beneath the waves in as little as one to five minutes. By the end of the day's multiple attacks, all six commercial ships in the convoy and one escort warship were destroyed.

Casualties and Survivors

The rapid sinking resulted in one of the deadliest maritime POW tragedies of World War II. Trapped in the dark holds with hatches sealed or obstructed, hundreds of men were crushed, incinerated, or drowned. Those who managed to reach the surface found absolute chaos, with Japanese guards reportedly hindering their escape rather than offering aid.

Of the 1,289 POWs aboard, an estimated 1,047 perished in the attack and its immediate aftermath. Additionally, 11 Japanese crew members and possibly over 100 Japanese passengers, troops, and guards died. Only around 240 POWs survived the sinking. A few extraordinary individuals, like British Cpl. Charles Stott, managed to swim to the Philippine coast and joined local guerrillas to fight the Japanese. The majority of survivors, however, were picked up from the water over the next 24 hours by Japanese rescue craft. These recaptured men were transported back to Bilibid Prison, and many were later placed on other infamous Hell Ships, such as the Oryoku Maru and Enoura Maru, where some ultimately perished before the war's end.

Legacy and Memorialization

The destruction of Hofuku Maru is an indelible part of the broader, tragic legacy of the Japanese hell ships. By the end of the war, 134 Japanese hell ships had transported roughly 126,000 Allied POWs. While thousands perished from the horrific conditions inside the holds, the greatest cause of fatalities was Allied attacks, which inadvertently killed more than 19,000 of their own men. Hofuku Maru stands as one of the deadliest examples of this intelligence disconnect.

Today, the ship is remembered not only for the sheer scale of the lives lost on September 21, 1944, but for the dark juxtaposition of its history. In 1920, the ship was a vessel of salvation, safely returning defeated German soldiers under the accepted international conventions of a civilized world. By 1944, stripped of its diplomatic dignity and operating under the totalitarian grip of the Imperial Japanese Army, the very same ship had become a floating tomb. The story of Hofuku Maru remains a harrowing testament to the brutal degradation of human rights during the Pacific War and the devastating reality of friendly fire at sea.
