Shii Izumi is a Japanese writer who explores the borderlands of symbol, myth, and psychology. For many years, they have been searching for ways to read the “meaning” that lies within the inner world, working privately on research and creative projects.

Along the way, several projects crystallized: the Greek-mythology–based symbolic system Theogonia Oracle, the dream-interpretation series Dream Translation, and the observation-based human-understanding tool Understanding Others Test.

These works were first made public in August 2025, which marked the beginning of Shii Izumi’s outward-facing creative activities. Since then, they have been developing a body of work that weaves together creative writing, psychology, and mythic thinking to explore human beings as living stories.

Profile

Shii Izumi is a Japanese writer and symbolic interpreter whose work is grounded in symbol, myth, and psychology. Their main focus is to read the meanings and narrative structures that dwell in the inner world, combining mythic thinking with psychological perspectives.

Their main fields of work include the Greek-mythology-based symbolic system Theogonia Oracle, the creative dream-interpretation series Dream Translation, and the observation-based human-understanding tool Understanding Others Test.

Shii Izumi began sharing their work publicly in August 2025. Since then, they have continued to develop multiple projects, working in both creative and analytical modes around a central theme: symbolic approaches to understanding each person’s unique story.

Major Projects

Theogonia Oracle

A symbolic system that reinterprets the gods of Greek mythology as a set of 24 oracle cards designed to illuminate a person’s inner themes.

The cards organize Olympian and primordial deities into “light” and “shadow” aspects, blending mythic structure with psychological insight. Beyond its divinatory function, it serves as a symbolic framework for self-reflection and understanding others.

Dream Translation (Japanese only)

A creative dream-interpretation series that transforms dream symbols into quiet, reflective prose. Rather than offering literal explanations, it re-reads dream imagery as inner narrative.

Worldview & Approach

At times, a faint echo of ancient myth brushes quietly against the human heart.
That slight tremor opens the door to an inner story.

— Shii Izumi

At the center of Shii Izumi’s creative and interpretive work is the idea that personal inner experience often takes on a mythic structure. Feelings such as anxiety, desire, intuition, and conflict can resonate with the forms of old myths and allegories.

This perspective is closely connected to an interest in Jungian views of symbol and in the archetypal structures found in myth. Izumi consistently uses an approach that reads “inner stories” through symbols, whether they appear in dreams, relationships, or turning points in life.

Theogonia Oracle is designed as a symbolic system that reorganizes the qualities of Greek deities into light and shadow aspects, offering one way to understand personal themes through a mythic framework. In Dream Translation, the psychological implications concealed in dream images are rendered into quiet, poetic prose in order to grasp the meanings that lie behind them.

The Understanding Others Test analyzes how differences in traits can create friction or misunderstanding, organizing them from an observational and structural point of view. Together, these diverse projects share a common core: reading the stories that live within people through the language of symbol.
