People tend to conflate some of the issues around the surrender for various reasons. The quick and dirty facts are that the surrender was unconditional and nothing short of complete acceptance of the allied occupation and creation of a post war constitution was going to fly. Now, the issue of the emperor was a little opaque. McArthur could have removed him day one, and that’s what Hirohito expected to happen, but McArthur decided he’d be better off with him at the head of a constitutional monarchy but he did require him to formally renounce his divinity in Jan. of 1946.

Prior to the formal surrender acceptance the Japanese had been steadfast that the emperor would remain, and remain divine.

The safe, swift and mostly violence free immediate landing of troops on Japan was an amazing result after such a brutal war.
