On Iwo Jima, the Japanese commander admitted before the battle that it was unwinnable, yet he refused to surrender and the defending force basically fought until the last man. They had approximately 21,000 troops and wikipedia lists 18,000 dead, 216 taken prisoner, and 3,000 in hiding. They wounded 20,000 Allies and killed another 6,000. So yeah, the invasion of Japan itself could have been much, much worse than the bombing was.
Here's another post about the next battle, at Okinawa, where the Allied casualty lists include 26,000 "psychiatric casualties":
"More mental health issues arose from the Battle of Okinawa than any other battle in the Pacific during World War II. The constant bombardment from artillery and mortars coupled with the high casualty rates led to a great deal of men coming down with combat fatigue. Additionally the rains caused mud that prevented tanks from moving and tracks from pulling out the dead, forcing Marines (who pride themselves on burying their dead in a proper and honorable manner) to leave their comrades where they lay. This, coupled with thousands of bodies both friend and foe littering the entire island, created a scent you could nearly taste. Morale was dangerously low by the month of May and the state of discipline on a moral basis had a new low barometer for acceptable behavior. The ruthless atrocities by the Japanese throughout the war had already brought on an altered behavior (deemed so by traditional standards) by many Americans resulting in the desecration of Japanese remains, but the Japanese tactic of using the Okinawan people as human shields brought about a new aspect of terror and torment to the psychological capacity of the Americans.[15]"
