Not for long. Japan's domestic supplies were carried mostly on interisland steamers. The submarine blockade and aerial mining program had already destroyed that. The 1946 famine would likely have ended the war whether or not the military leadership wanted it, I believe.
And the USAAF had not yet begun a campaign against the Japanese transportation network; this was set to start in September.
For what it's worth, the USSBS in its postwar examination concluded that, even absent the use of the atomic bombs and a Russian declaration of war, the Japanese would have surrendered by December 1945 at the latest, rendering a full invasion unnecessary. The Japanese position was simply untenable, and most of its public and government understood, even if they would not admit it publicly, that Japan had lost the war. The fact that the U.S. bombers could range freely over the nation was a sure sign the Japanese military had lost the ability to defend the homeland.
