The Bombing of Chiba in World War II (千葉空襲, Chiba kūshū) was part of the strategic bombing campaign waged by the United States of America against military and civilian targets and population centers during the Japan home islands campaign in the closing stages of World War II, and included two separate air raids in 1945. The second, and larger, air raid of July 6, 1945 is also referred to as the “Tanabata Air Raid”, as it occurred on the night of a traditional festival.
