The atomic bombings in Japan at Hiroshima on 6 August 1945, followed by that of Nagasaki on 9 August, precipitated the abrupt end of the war. On 15 August 1945, Japan announced its official unconditional surrender to the Allied Powers. On 24 August, Suga officially announced to the prisoners at Batu Lintang that Japan had surrendered. Suga was a broken man: he believed that his entire family had been killed in the bombing of Hiroshima. In fact, his wife and three of his children survived the bombing though his sister Teru and brother-in-law Tamekichi Tanaka as well as his son Makoto were killed.
