Oshin enlists Ken's help to find Kayo in Tokyo's red-light district. Now a prostitute, a broken and dissipated Kayo reveals that Masao had gambled Kagaya's entire fortune away on rice derivatives that went awry. She and her parents had come to Tokyo but her mother fell ill after her father died, so Kayo had sold herself into prostitution to pay for her mother's medical bills. Unable to even bring their bones back to Sakata for a proper burial, Kayo now lives for her son Nozomi.
