The answer is no. A naval blockade and fire bombing of military targets would have been just as effective. I have an extensive background in military history and have read the material. A physically weak Japanese population and a severely crippled military infrastructure would have made occupation a less costly option than some claim.
What was the big rush? We had the ships and airpower to wait it out.

Of course waiting it out would have killed a lot of Japanese civilians too.
Some years ago I was working at the Dept. of Veterans Affairs, and it was announced one day that the director of one of the service organizations was retiring that day. He was an old guy, “Mr. H.” and I decided to stop off at his office for the event.
Some people seem to be taciturn their whole lives, and then turn loquacious at their retirement party. That turned out to be the case with Mr. H. as he got to reminiscing, as he talked to the small group. He had been a POW in Japan at the time. He spoke of having survived the Bataan Death March. Many—most—of his compatriots did not. After the death march, he was in a prison camp under terrible conditions.
Then came Hiroshima and Nagasaki. The war ended. He was freed and repatriated. He spoke warmly of Harry Truman.
After his retirement ceremony I was going to the cafeteria with a co-worker.
“How was Mr. H’s retirement party?” he asked
“Pretty good,” I said, “He told some stories. Harry Truman was his hero.”
“Why?” he asked.
“Because of the bomb,” I said. “That’s why he’s alive today.”
“Darn,” said my friend, “I always seem to miss the good ones.”
A blockade wouldn’t have saved Mr. H. He would have starved. He was already nearly starved, so the blockade would have finished him off, along with millions of Japanese civilians. Would a blockade have caused fewer deaths than Hiroshima and Nagasaki? I don’t know, but I doubt it.
Those who were personally involved in the events of World War II have pretty much all died off. We, at some historical remove, get to sit around second guessing their actions, but things may have looked somewhat different at the time.
My brother’s father in law is a WW-II veteran. He’s 91 years old. He has a piece of a Japanese kamikaze fighter plan hanging on his wall. It missed him. I listen to his stories too, because first hand history is best.
