Following the outbreak of the Japan-China war in 1937, the Japanese Red Cross worked with government officials on a series of posters to educate the public about potential air raid defense.

Designed to create a pattern of “anti-aircraft defense” thought, these were displayed as part of a military exhibition in the Red Cross Museum.

New laws following the outbreak of war required citizens to take protective measures against gas attacks. The poster series covers the basics of evacuation and rescue, disinfection, gas identification, symptoms of poisoning, treatment and relief.
