The Imperial Japanese Navy (Nihon Kaigun) 1900-1945' is a comprehensive study that provides biographical information on several thousand Japanese officers of Admiral rank who served the Empire between 1900-1945, from the time that they attained flag rank, with photographs of most of the senior Admirals. The book also includes an order of battle of the Japanese Navy (IJN) during these years, with a listing of the highest administrative and field commands and their commanders. To complete the overall scope of the subject matter, seven chapters provide information about the aircraft carriers, battleships, and cruisers of the IJN, with histories that include the dates that the vessels were launched, their eventual fates, and photographs of these important elements of the IJN.
