Extent of Japanese civilian participation in Operation Downfall?

I'd recommend Googling 'Operation Hulu' & related ops & what they were providing support for.

1. Project Hula, not Operation Hulu
2. The amount of shipping capacity received was barely enough to transport 9,100 men. That is enough to take the Kuriles, but not attack Hokkaido, let alone Honshu. The US was not going to let the Soviets get at Japan proper willingly, especially not with Truman as President.

My take is different. The boat types were assault types, not long range transports. In that context 9,100 men is not a bad initial lift for a large scale landing.
