Won’t change anybody’s mind, but just for background:

What the military leaders did not know was that by the end of July the Japanese had been saving all aircraft, fuel, and pilots in reserve, and had been feverishly building new planes for the decisive battle for their homeland.
As part of Ketsu-Go, the name for the plan to defend Japan – the Japanese were building 20 suicide takeoff strips in southern Kyushu with underground hangars. They also had 35 camouflaged airfields and nine seaplane bases.
On the night before the expected invasion, 50 Japanese seaplane bombers, 100 former carrier aircraft and 50 land based army planes were to be launched in a suicide attack on the fleet.
The Japanese had 58 more airfields in Korea, western Honshu and Shikoku, which also were to be used for massive suicide attacks.
Allied intelligence had established that the Japanese had no more than 2,500 aircraft of which they guessed 300 would be deployed in suicide attacks.
In August 1945, however, unknown to Allied intelligence, the Japanese still had 5, 651 army and 7,074 navy aircraft, for a total of 12, 725 planes of all types. Every village had some type of aircraft manufacturing activity. Hidden in mines, railway tunnels, under viaducts and in basements of department stores, work was being done to construct new planes.
When the invasion became imminent, Ketsu-Go called for a fourfold aerial plan of attack to destroy up to 800 Allied ships.
While Allied ships were approaching Japan, but still in the open seas, an initial force of 2,000 army and navy fighters were to fight to the death to control the skies over Kyushu. A second force of 330 navy combat pilots were to attack the main body of the task force to keep it from using its fire support and air cover to protect the troop carrying transports. While these two forces were engaged, a third force of 825 suicide planes was to hit the American transports.
As the invasion convoys approached their anchorages, another 2,000 suicide planes were to be launched in waves of 200 to 300, to be used in hour by hour attacks.
Facing the 14 American divisions landing at Kyushu would be 14 Japanese divisions, 7 independent mixed brigades, 3 tank brigades and thousands of naval troops. On Kyushu the odds would be 3 to 2 in favor of the Japanese, with 790,000 enemy defenders against 550,000 Americans.
All along the invasion beaches, American troops would face coastal batteries, anti-landing obstacles and a network of heavily fortified pillboxes, bunkers, and underground fortresses. As Americans waded ashore, they would face intense artillery and mortar fire as they worked their way through concrete rubble and barbed-wire entanglements arranged to funnel them into the muzzles of these Japanese guns.
On the beaches and beyond would be hundreds of Japanese machine gun positions, beach mines, booby traps, trip-wire mines and sniper units. Suicide units concealed in “spider holes” would engage the troops as they passed nearby. In the heat of battle, Japanese infiltration units would be sent to reap havoc in the American lines by cutting phone and communication lines. Some of the Japanese troops would be in American uniform, English-speaking Japanese officers were assigned to break in on American radio traffic to call off artillery fire, to order retreats and to further confuse troops. Other infiltration with demolition charges strapped on their chests or backs wold attempt to blow up american tanks, artillery pieces and ammunition stores as they were unloaded ashore.
Beyond the beaches were large artillery pieces situated to bring down a curtain of fire on the beach. Some of these large guns were mounted on railroad tracks running in and out of caves protected by concrete and steel.
In the mountains behind the Japanese beaches were underground networks of caves, bunkers, command posts and hospitals connected by miles of tunnels with dozens of entrances and exits. Some of these complexes could hold up to 1,000 troops.
In addition to the use of poison gas and bacteriological warfare (which the Japanese had experimented with), Japan mobilized its citizenry.
Had Olympic come about, the Japanese civilian population, inflamed by a national slogan - “One Hundred Million Will Die for the Emperor and Nation” - were prepared to fight to the death. Twenty Eight Million Japanese had become a part of the National Volunteer Combat Force. They were armed with ancient rifles, lunge mines, satchel charges, Molotov cocktails and one-shot black powder mortars. Others were armed with swords, long bows, axes and bamboo spears. The civilian units were to be used in nighttime attacks, hit and run maneuvers, delaying actions and massive suicide charges at the weaker American positions.
At the early stage of the invasion, 1,000 Japanese and American soldiers would be dying every hour.
Intelligence studies and military estimates made 50 years ago, and not latter-day speculation, clearly indicate that the battle for Japan might well have resulted in the biggest blood-bath in the history of modern warfare.
The invasion of Japan never became a reality because on August 6, 1945, an atomic bomb was exploded over Hiroshima. Three days later, a second bomb was dropped on Nagasaki. Within days the war with Japan was at a close.
