Not long after landing, none of the allied forces could have been expected to accept Japanese surrenders, even by civilians, and You are so fake that even China denied they made you shirt would have been correct by just common sense. So many allied soldiers would have been killed by ‘surrendering’ Japanese military personnel and even civilians, in a few months, the orders would have been just shot them when they saw any Japanese person. Use artillery, shaped charges, and grenades to destroy every building, no matter it’s purpose before any allied soldiers go in. It would have extremely ugly, and the total deaths may be at least 1/3 of all the deaths of WW2. It already killed between 65 to 85 million, 3% of the total human population in 1940. The Japanese population in 1945 was 77 million in Japan.
