English translation of the Japanese original published at https://doi.org/10.5281/zenodo.19516408 This paper is an exploratory study examining the possibility of structural similarity between the seven classical celestial bodies in Western astrology and the 5W1H framework—a fundamental format for describing experience linguistically. The 5W1H represents a set of interrogative frames long employed by humans to organize and articulate events and experiences, while the seven celestial bodies are basic units refined within the astrological tradition to symbolically articulate the major dimensions of human experience. The paper presents a hypothetical mapping in which Who corresponds to the Sun and Moon, When to Mars, Where to Mercury, What to Saturn, Why to Venus, and How to Jupiter, and examines whether this correspondence may amount to more than mere coincidence. Furthermore, the paper argues that, despite their distinct origins, both systems share the common endeavor of compressing the totality of complex human experience into a finite set of elements to render it describable. Through this discussion, the paper aims to offer a perspective that reframes astrology not merely as symbolic interpretation but as a descriptive system for organizing human experience.
