His approach relied on the katazome method, which involves applying a rice-paste resist through hand-cut stencils before adding colour. While many Mingei artists remained anonymous, Serizawa became known for modernising this craft. He designed items such as kimonos and book covers. His work is defined by bold shapes and a clear sense of pattern. He used natural pigments and hand-made paper, ensuring each piece retained the tactile quality of a functional object.

Modern collectors value Serizawa for his graphic clarity and the warmth of his materials. His prints bridge the gap between fine art and everyday design. Because his work originated from a movement that celebrated utilitarian beauty, these prints fit naturally into contemporary homes. The combination of historical technique and bold compositions makes his stencils feel current. They bring the Mingei philosophy into a space through structured, hand-crafted imagery.
