An ultimatum was issued to Japan from Potsdam, but no mention of atomic bombs was made in it as they were classified and the only people at Potsdam cleared to discuss them were Truman and Churchill.The first time the Japanese were told of the atomic bomb was after the bombing of Hiroshima.
The Battle of Okinawa did not lead to the atomic bomb, this battle happened in 1945 just a couple of months before the Manhattan Project completed the atomic bomb which they had been working on since 1942. With or without the Battle of Okinawa the atomic bomb would have been finished at the same time and dropped on Japan at the same time.

No, at no time have the Japanese ever had atomic bombs!

No, they are not the same. The atomic bomb was a specific weapon developed during World War II, while the nuclear age refers to the period starting from when nuclear technology and weapons became a significant part of global affairs, which continued past the use of the atomic bomb.
