Today marks the anniversary of the world’s first nuclear bomb explosion. 
That bomb was dropped by the United States airforce on Hiroshima, Japan on August 6th 1945.
 It was followed three days later by a second nuclear bomb, also dropped by the U.S. airforce, on Nagasaki, Japan.
In Portland, three days of events have been organized to commemorate the horrific events of 1945. 
Chisao Hata is one of the organizers.  She spoke with KBOO News today
