Hiromi Morishita is a Japanese manga artist born on September 7, 1962, in Nara Prefecture. She made her professional debut in 1982, with her early work appearing in both the magazine Garo and the pages of Weekly Shonen Jump, where her story Shonen wa Seishun o Sukidatta was a finalist in a newcomer contest. Initially, her career involved a range of story manga before she eventually focused on the four-panel comedy format, a shift that led to her greatest mainstream success.

Morishita is best known as the creator of Shōnen Ashibe, a four-panel manga that was serialized in Weekly Young Jump from 1988 to 1993. The series follows the daily life of a young boy, Ashibe, and his family, who live with a pet white spotted seal. The manga became a significant hit and was adapted into several anime productions. The first anime series, Shōnen Ashibe, aired in 1991, followed by a sequel, Shōnen Ashibe 2. Decades later, the franchise saw a revival with Shōnen Ashibe GO! GO! Goma-chan, an anime that began broadcasting in 2016, introducing the characters to a new generation.

Beyond Shōnen Ashibe, her body of work is extensive and demonstrates her range within the comedy genre. She received the highest prize from the Japan Cartoonists Association in 1992 for the four-panel series Koko Dake no Futari. Another notable work is Osaka Hamlet, a story manga that was serialized in Manga Action starting in 2005 and was later adapted into a live-action film in 2009. Her other credited works include series such as Super Maruden, Enya Kodomo Ninja Chapter, and Himawari Martial Arts Book, as well as the long-running strip Uchi no Baai wa, which was serialized in the evening edition of the Mainichi Shimbun newspaper.

Her artistic identity is characterized by a distinct evolution in style. Early in her career, her art reflected influences from contemporaries, but she later developed a signature approach that pairs deceptively simple, cute character designs with sharp, often darkly humorous observations of human nature. This combination of warmth and social satire is a hallmark of her storytelling, evident in both her four-panel comedies and her longer narrative works. Morishita is married to fellow manga artist Keisuke Yamashina. Her significance in the industry rests on her ability to master the four-panel format, creating beloved, long-running series that have achieved critical recognition and sustained popularity across multiple anime adaptations.
