Fact-Checking Sadako Sasaki: The Role of Nurse Yasunaga and Dr. Numata

Sadako Sasaki & the Hiroshima Maidens: Historical Record

Sadako Sasaki (1943–1955) developed leukemia at age 12 after atomic‑bomb exposure at age 2. She folded origami cranes in hospital, becoming a global peace symbol.

Nurse Yasunaga & Dr. Numata

• No credible historical records (Hiroshima Peace Memorial Museum archives, Sasaki family accounts, peer‑reviewed biographies) link a “Nurse Yasunaga” or “Dr. Numata” to Sadako’s direct care.
• Her attending physicians included Dr. Shigetaka Sasaki (no relation) and nursing staff at Hiroshima Red Cross Hospital.
• The names may originate from fictionalized accounts, confusion with other hibakusha, or later dramatizations.

Verified Facts

• Sadako folded ~1,300 cranes; classmates completed 1,000 after her death.
• Children’s Peace Monument (1958) in Hiroshima Peace Park funded by schoolchildren nationwide.
• Her story inspired the International Campaign to Abolish Nuclear Weapons (ICAN).

Always cross‑reference with primary sources (museum archives, peer‑reviewed history) when evaluating anecdotal claims about historical figures.
