Historical Background

Before the war, Ryusei Maru operated in commercial shipping routes linking Japan with ports in China and Southeast Asia. Following Japan’s wartime mobilization, the vessel was requisitioned to support military logistics.

As the war progressed, merchant ships increasingly served as transports for prisoners of war.

POW Transport Mission

POWs captured in the Philippines, Hong Kong, and Southeast Asia were moved aboard ships like Ryusei Maru to work in Japanese industrial facilities.

Conditions Aboard

POWs endured extremely harsh conditions including:

  • cramped cargo holds

  • lack of fresh air

  • insufficient food

  • exposure to disease

Many prisoners died during transport due to heat exhaustion and dehydration.

Wartime Operations

Ryusei Maru sailed during a period when Allied submarines and aircraft were increasingly attacking Japanese shipping.

The ship’s survival reflects the chaotic and dangerous conditions faced by both Japanese crews and POW passengers during the later years of the war.

Aftermath

Prisoners transported aboard Ryusei Maru were distributed among labor camps throughout Japan.

These camps supplied workers to:

  • mines

  • steel plants

  • military construction projects

Many prisoners were liberated only after the war ended in 1945.
