History
In the Summer of 1944, things were not going well for the Japanese. The Americans were approaching Japan, and from the Japanese viewpoint, an invasion of the homeland was not too far away. Conventional weaponry seemed to be ineffective. Due to the fact that Japan was far behind the U.S. in industrial development, existing air and naval forces were being used up far beyond Japan’s ability to replace equipment and personnel. The leaders still thought they could win, but it was obvious to many military and naval people that something radical was needed.
