Arisan Maru
Definition
The Arisan Maru was a 6,886-ton Japanese freighter used as a hell ship that was torpedoed on 24 October 1944 in the Bashi Channel between the Philippines and Taiwan by the American submarine USS Shark while carrying about 1,800 Allied prisoners of war from Manila to Japan. Nearly all the prisoners died in the sinking—among the deadliest maritime disasters in the Pacific war—while the attacking submarine herself was lost with all hands, evidently to Japanese counterattack.

Examples and Analogies
The Arisan Maru is often paired with the Oryoku Maru as the defining hell-ship tragedies: prisoners locked below decks died with their captors’ vessel, a catastrophe likened in survivor literature to being entombed—locked holds, no lifeboats for POWs, and no marking to warn attacking submarines.
Usage Scenarios
The sinking anchors discussions of Japanese treatment of prisoners of war, is memorialized in U.S. POW remembrance programs, appears in submarine-force histories of USS Shark, and illustrates why survivors’ oral histories became central to World War II atrocity documentation.
Strategies
A handful of prisoners survived by clinging to wreckage and rafts; some were recaptured, and a few reached Allied lines after months adrift or hidden by Chinese coast dwellers, whose testimony shaped postwar understanding. Their accounts guided war-crimes investigators on conditions in the holds.
Security and Safety Measures
The disaster underscores the lethal consequences of transporting prisoners in unmarked ships without lifeboat access, adequate water, or hold ventilation. Postwar law and custom—reinforced by the Geneva Conventions—require protecting POW transports and notifying belligerents of their movements, precisely the safeguards absent in the hell-ship voyages.
Historical Context
In October 1944, as American forces landed at Leyte, Japan accelerated moving POW labor from the Philippines to the home islands. The Arisan Maru sailed from Manila on 11 October carrying prisoners taken at Bataan, Corregidor, and elsewhere. On 24 October USS Shark torpedoed her; the ship broke and sank within hours. Japanese escorts rescued their own survivors while abandoning the prisoners, of whom only a handful, around nine men, ultimately survived to tell of the voyage. USS Shark was sunk around the same period, likely by Japanese escort vessels.
Challenges and Controversies
Debates persist over exact casualty counts and over the fate of USS Shark, believed destroyed by destroyer escorts after the attack. Survivors and historians also faulted the postwar handling of accountability, noting that responsibility for hell-ship deaths was diluted across Japanese commands that claimed the transports were legal auxiliaries in a war zone.
