Understanding the Context

Sadako Yamada (1955–1955) was a Japanese girl who lived during one of the darkest chapters in modern history—the culmination of World War II and the atomic bombings of Hiroshima and Nagasaki. At just two years old, Sadako survived the 1945 atomic bomb strike on Hiroshima but suffered long-term health effects, including leukemia, caused by radiation exposure.

Tragically, her illness lasted less than a year before she passed away in 1955. In her short life, and especially in her final days, Sadako folded a thousand origami cranes—known in Japanese folklore to grant wishes—symbolizing peace and healing. Her act, rooted in hope and spiritual belief, transformed a deeply personal tragedy into a global symbol of peace activism.
