Visualizing Film Narrative: Applying the C4 Model to "Oi, Ohoi", a Systems Approach to Narrative Structure Analysis

This paper introduces an innovative methodology for film narrative analysis by adapting the C4 model from software engineering to humanities scholarship. Using the hypothetical film "Oi, Ohoi" (2025)-which depicts the life of Edo period female painter Katsushika Oei-as a case study, this research demonstrates how hierarchical system modeling can illuminate complex narrative structures, character relationships, and thematic development. The C4 model's four-level abstraction (Context, Container, Component, Code) enables both macro-level contextual analysis and micro-level examination of specific expressive techniques. This interdisciplinary approach bridges information science and film studies, offering new tools for understanding how narratives function as complex systems. The methodology proves particularly effective for analyzing films with intersecting social, psychological, and artistic dimensions, revealing structural patterns invisible to traditional close reading alone.
