The Imperial Japanese Navy was a pioneer in naval aviation, having commissioned the world's first built-from-the-keel-up carrier, the 'Hosho'. Throughout the 1920s and 1930s, it experimented with its carriers, perfecting their design and construction.

As a result, by the time Japan entered World War 2 and attacked the United States at Pearl Harbor in 1941, it possessed a fantastically effective naval aviation force. Carriers would roam the Pacific with near impunity, destroying their opponents at will.

This book covers the design, development, and operation of IJN aircraft carriers built prior to and during World War 2. Pearl Harbor, Midway, and the first carrier vs carrier battle, the battle of the Coral Sea, are all discussed.
