Mrs. Yokokawa

清太・節子の母

She is first seen fastening a hood onto Setsuko, instructing her to behave well and obey her brother as the family gets ready for the bombing. She then remarks that she should head to the shelter, telling them to join her there as quickly as possible. Seita asks if she has her heart medication, and she confirms she does, gesturing toward her bag and telling him not to worry. She then departs.
Upon Seita and Setsuko’s arrival at the shelter, Seita is informed that his mother was severely injured. He rushes to see her and finds her sleeping on a bed, heavily bandaged, bloody, and burned. Horrified, Seita painfully mentions that his mother has heart trouble and asks if she can receive her medicine. The man present says he will check. When the man leaves, Seita attempts to communicate with her but receives only soft breathing in response.
When Seita returns to Setsuko, he tells her that their mother is hurt and in the hospital but will recover soon, afraid to reveal the truth to his little sister.
Seita's mother's corpse is then seen being loaded into a truck, with flies and maggots crawling over it, while a man explains that she remains bandaged because her body is too gruesome to view; another man states that she must be transported on the truck that day due to the heat. Seita watches them carry her away. She is then cremated in a massive fire along with many other bodies.
