そのころの広島
   

Air-raid Siren
Starting around fall of 1944, US military planes flew over Japan's air space to carry out air raids. When a fighter plane approached an area, an air-raid siren sounded and people ran to air-raid shelters for cover.
   In 1945, the U.S. military attacked the major Japanese cities from the air, one after another. The air strikes did severe damage. Though sirens sounded in Hiroshima as well , air strikes were rare.

Hiroshima began air-raid training as early as 1932, but full-scale drills did not begin until 1937. Citizens' Defense Reserves were established as air defense organizations. They organized city residents into compulsory practice sessions for taking shelter and fighting fires with bucket relays.
