All indications pointed to an American drive towards the Mariana Islands and the Carolines. In Marchthe Japanese 31st Armycommanded by General Hideyoshi Obatawas activated to garrison this inner line. The Japanese Army had many armies, but the huge U.
Army only had ten at its peak, with the 4th Army, the 6th Army, the 8th Army, and the 10th Army being in the Pacific Theater. Also, the 10th Army only fought on Okinawa in the spring of Iwo Jima served as an early warning station which radioed reports of incoming bombers back to mainland Japan, allowing Japanese air defenses to be prepared for the arrival of American bombers.
At the same time, with reinforcements arriving from Chichi Jima and the home islands, the Army garrison on Iwo Jima had reached a strength of over 5, men.
Moreover, aircraft losses throughout had been so heavy that, even if war production were not affected by American air attacks, combined Japanese air strength was not expected to increase to 3, warplanes until March or April Even then, these planes could not be used from bases in the Home Islands against Iwo Jima because their range was not more than km mi.
Besides this, all available warplanes had to be hoarded to defend Taiwan and the Japanese Home Islands from any attack.
In a postwar study, Japanese staff officers described the strategy that was used in the defense of Iwo Jima in the following terms: In the light of the above situation, seeing that it was impossible to conduct our air, sea, and ground operations on Iwo Jima toward ultimate victory, it was decided that in order to gain time necessary for the preparation of the Homeland defense, our forces should rely solely upon the established defensive equipment in that area, checking the enemy by delaying tactics.
Even the suicidal attacks by small groups of our Army and Navy airplanes, the surprise attacks by our submarinesand the actions of parachute units, although effective, could be regarded only as a strategical ruse on our part.
It was a most depressing thought that we had no available means left for the exploitation of the strategical opportunities which might from time to time occur in the course of these operations.
Iwo Jima was strategically important: In addition, it was used by the Japanese to stage air attacks on the Mariana Islands from November through January The capture of Iwo Jima would eliminate these problems and provide a staging area for the Operation Downfall - the eventual invasion of the Japanese Home Islands.
The distance of B - 29 raids could hypothetically be cut in half, and a base would be available for P Mustang fighters to escort and protect the bombers. In light of the optimistic intelligence reports, the decision was made to invade Iwo Jima: So successful was the Japanese preparation that it was discovered after the battle that the hundreds of tons of Allied bombs and thousands of rounds of heavy naval gunfire left the Japanese defenders almost unscathed and ready to inflict losses on the U.
Marines unprecedented up to that point in the Pacific War.
