In Singapore... The surrender of Japanese forces in Southeast Asia is concluded before Admiral Lord Mountbatten, the Supreme Commander in South East Asia, in the Council Chamber of the Municipal Buildings. Japanese General Itagaki signs on behalf of Field Marshal Count Terauchi (who is suffering from a paralytic stroke).

In Occupied Japan... Field Marshal Sugiyama, former Commander in Chief of the Japanese Home Army, commits suicide together with his wife. Meanwhile, General MacArthur orders the dissolution of the Black Dragon society (the secret terrorist organization which for many years played a prominent role in Japanese imperialist policies and had been responsible for many political assassinations) and the arrest of seven of its leaders.

In Mexico City... The Mexican government issues a decree nationalizing all deposits of uranium, actinium and other radioactive minerals that might be used in the production of atomic bombs. Such deposits occur in the states of Chihuahua, Durango and Guerrero.
