This examines the intersection of historical literature and modern business strategy by analyzing customer-centric marketing through two distinct lenses.
It first explores how the Kojiki and Nihon Shoki, Japan's oldest chronicles, served as early examples of audience segmentation by tailoring their language and tone to either domestic or international readers. The discussion then transitions to a contemporary case study of Casio’s Sa-Dokei, a specialized watch designed exclusively for sauna enthusiasts.
By identifying unmet needs such as high-heat resistance and specific timing functions, Casio successfully applied the same principles of targeting and situational utility found in ancient texts. It illustrates that effective marketing requires a deep understanding of who the audience is and how to adapt communication to fit their specific context. Underpinning both examples is the idea that success stems from prioritizing the user's perspective to create meaningful value.
