Tsunami Umino is a Japanese manga artist from Hyogo Prefecture. She made her debut in 1989 with "Otsukisama ni Onegai," which received recognition in the eighth Nakayoshi New Manga Award, and later expanded her work from girls’ manga to comics for adult women. Her representative work, "The Full-Time Wife Escapist," follows graduate-school alumna Mikuri Moriyama, who is unable to secure stable employment and enters a contract marriage with office worker Hiramasa Tsuzaki, treating domestic labor as paid work. As their relationship develops from employer and employee to partners managing a household together, the manga examines the economic value of housework, insecure employment, gendered divisions of labor, and the negotiation of responsibilities within marriage. It received the 39th Kodansha Manga Award in the Shojo category and was adapted into a television drama.
