a) Tokyo, Japan

The first U.S. air raid on Japan during World War II targeted Tokyo. This daring operation, known as the Doolittle Raid, occurred on April 18, 1942, and was led by Lieutenant Colonel James Doolittle. Though the raid caused relatively minor physical damage, it had a significant psychological impact, boosting American morale and demonstrating Japan’s vulnerability to air attacks, which led to strategic changes in Japanese defense plans.
