Mutsuko Haishi (hapun pottery) is a ceramic artist based in Osaka. Using red rough clay as her base material, she handcrafts each piece of tableware and flower ware individually, combining colored slip with freehand line drawing. She employs a variety of techniques including wheel throwing and press molding. After a roughly 20-year hiatus, she returned to ceramics in 2019 during the COVID-19 pandemic, and has since become widely known for her playful illustrations and soft color palettes.
