Haiku is a interesting form of short Japanese poetry. One of the most famous haiku writers is Yasuhiko Shigemoto, who has a book, “My Haiku of Hiroshima”, about the Hiroshima bomb. He has a first hand testimony because he was in Hiroshima when the atomic bomb was dropped. Remember, about fifty thousand people died in a second.
This form of art caught my interest so I took some of his haiku, from this webpage, and spread over a photo of the Nagasaki bomb.
