No, Japan didn't immediately refuse after the bombing of Hiroshima. After the bombing, Emperor Hirohito (the Japanese leader during the Second World War) went into consultation with the Imperial War Council (of Japan) where they were deciding whether or not to surrender. However, three days after the bombing of Hiroshima, America bombed Japan again, this time in Nagasaki. Roughly a week after the Nagasaki bombing, Emperor Hirohito on 15 August 1945 announced surrender via radio broadcast. He officially surrendered in written agreement later that year on 2 September 1945.
