After Germany's surrender on May 7th, 1945, Japan continued to produce propaganda and war efforts within the Pacific.
Even after being pushed into the Japanese mainland, their cities burning to ash with all of the regular bombings, their military being diminished along with it's innocent civilians, Hiro-Hito never gave word of surrender.
On August 6th and 9th that same year, the nuclear bombs "Fat Man" and "Little Boy" were dropped on the cities of Hiroshima and Nagasaki, driving the Imperial Japanese Army to surrender. The destruction has long been repaired, but the scar on their culture still remains to this very day.
