A 2013-to-present seinen comedy manga by Sankakuhead, with a summer 2015 anime adaptation and fall 2017 season 2 anime by Doga Kobo. An alternative version of the manga was serialized for 2 chapters in 2012 before its current serialization.
The term himouto (干物妹) in the title is a merger of the term himono onna (干物女, "dried fish woman", referring to fish jerky junk food snacks that replace home-cooked meals) and the word imouto (妹, "younger sister"). Himono onna was coined by the manga Hotaru no Hikari, and refers to a young woman who leads a stable career but has little to no interest in romance and is generally reclusive, typically at home when not having to go out for her job. Her public and private lives are generally very different, with her public appearance being very clean, organized, and well-mannered. In contrast, her private appearance is messy, disorganized, and ill-mannered.
On December 20, 2025 the author released a video in which he stated that the manga was inspired by his younger sister, as well as other aspects of his life, such as his hamsters. His sister served as the model for Umaru, who fell ill between the publication of the sixth and seventh volumes (both released in 2015). She died sometime between the publication of the tenth and eleventh volumes (both released in 2017). He noted that working on the manga and attending the wrap-up celebrations for the first season of the anime, which occurred days after her death, was particularly difficult. However, he later continued work on the eleventh and twelfth volumes in her memory.
