Juro Urano is the father of protagonist Suzu Urano, residing in the coastal town of Eba near Hiroshima. He initially operates a family seaweed cultivation and trade business but shifts to factory work due to wartime conditions and economic pressures. Present in Hiroshima during the atomic bombing on August 6, 1945, he survives the initial blast but suffers radiation poisoning. His health declines over subsequent months until his death. His wife, Kiseno Urano, disappears in the bombing and is presumed dead.

Juro’s background remains consistent across the manga, 2016 anime film, and live-action adaptations. Official media confines his portrayal to his role as Suzu’s father and his occupation, excluding his personality, relationships beyond his immediate family, or events outside his documented fate. His death contributes to the narrative of familial loss from the atomic bombing, establishing Suzu’s origins and illustrating the impact of historical events on civilian lives.
