On August 6, 1945, Yamaguchi Tsutomu got up
happily. It was his last day in Hiroshima. He was going
back the following day to his family and home office in
Nagasaki. He had spent three months designing ships at
a company in Hiroshima.
On the last day of his assignment, he took a bus to the
office, but he realized that he had forgotten his seal for
stamping documents. He returned to the company house
to get it and left again for the office, this time by train.
When he was walking from the station to the office, he
saw a bomber flying and then two white parachutes
falling. Suddenly, there was a terrible "ball of fire," and
he was knocked unconscious.
