O-tane takes the boy to Chigasaki, where she learns that Kōhei and his father had been living in a rented room after their own house at Hachiōji was destroyed in the bombing. The landlady tells O-tane that the two had left for Tokyo a few days previously as Kōhei's father, a carpenter, hoped to find work there. She does not expect him back and does not know how to contact him. O-tane and Kōhei eat their lunch of rice balls on the sanddunes. O-tane tries to get rid of Kōhei by sending him down to the shore to collect some seashells for her and then running off, but the boy runs after her.
