The project aims to depict the development of modern haiku poetry in Japan during the 20th century. The rather limited research that has been conducted in this area has, with few exceptions, focused on male authors. It is therefore of interest to study the historical development based on a number of female authors. In this way, themes that are often missing in the works by male authors can also be included. A greater focus on the haiku's stylistic variants also becomes possible, as a male perspective is often limited to a depiction of power relations and group formations, and ignores aspects such as expression and aesthetics.
