At the top of the 9-meter-high monument there is a bronze statue of a girl stretching her arms up in the air and holding a golden crane, conveying hope for a peaceful future. Two statues, one on the right and one on the left side of the monument symbolize a boy, a girl and bright hope.

A bell, modelled after an ancient bronze bell, hands inside the tower. It was contributed by the Nobel prize winner, Dr. Hideki Yukawa, who was much moved by the feelings of the boys and girls. A golden crane suspended from the bell creates the sound of a windbell. On the front of the bell "A Thousand Paper Cranes" and on the back "Peace on the Earth and in the Heavens" is written in Dr. Yukawa’s handwriting. However, the bell and a golden crane are presently exhibited in the first-floor lobby of the East Building of the Hiroshima Peace Memorial Museum.

Directly under the monument, the words "This is our cry. This is our prayer. For building peace in this world," written by a junior high school student, are carved on a black granite block.
