Basically...Yes. They did what they did, with what was available to them. Tactic - The Japanese worked to adjust their Kamikaze tactics to suit the situation. However, given the multitude of Japanese aircraft types, both IJA & IJN, involved, this was only accomplished in a very general way. Training - How can you adjust training, when neither time nor fuel permitted very much training? Psychological preparation - Goes part and parcel with training...There was not a lot of time for it. Yes, a massed Kamikaze attack...Which the Japanese did use on occasion...And got slaughtered. Also, which I pointed out, the Japanese could not continuously sustain these kinds of attacks in numbers. Thus, I can only say that your "possible alternative" has little basis in the historical reality of 1945. Reading...Things called "books". I can recommend a few. As I pointed out, the Japanese were evolving their tactics...But, so were the Americans, both tactically and technologically. The Japanese had neither the time(by 1943), nor the fuel(by late 1944) to effectively train their pilots. Nor, did the Japanese possess an overwhelming superiority of numbers necessary to inflict crippling losses on the Americans. Also, the Japanese are facing an impending invasion of their home islands, as such, after Okinawa, they do not devote the men and material necessary for you "alternative scenario" in any of their Kamikaze attempts. Choosing, instead to husband their resources to fight off said invasion.
