A description of what an invasion of Japan actually would have entailed can be seen in Post 27 of http://www.freerepublic.com/focus/f-chat/3777953/posts

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.

Wow.
