Abstract
This study is an analysis of haiku using the systems theory, with its theoretical framework of fundamental informatics. Haiku has been composed and interpreted in relation to haiku-societies, haiku-associations and mass media. In addition, the Internet is being increasingly used for the creation and dissemination of haiku. Fundamental informatics understands mind, society, mass media and the Internet as hierarchically related autopoietic systems, or as hierarchical autonomous communication systems (HACSes). It then considers that the formation of meanings (which corresponds to the composition and interpretation of haiku in this paper) occurs on the basis of information, which emerges in mutual relationships between the HACSes. Fundamental informatics makes it possible to illuminate how haiku is composed and interpreted, under the influence of haiku-societies, haiku-associations, mass media and the Internet.
