Shared context is a design choice
Hiramatsu separates how much meaning depends on context from whether that context is socially inherited or deliberately produced by management
Premise
Calling an organization ‘high-context’ is too coarse for executive diagnosis. Two teams may both rely on shared understanding while one inherits it through stable relationships and the other deliberately builds it through rotation, routines, training, and common information environments. Low-context communication can likewise arise from deliberate codification or weak common background.
Shigemi Hiramatsu’s four-type communication-context model adds this second axis—how context is formed—to Edward T. Hall’s high-/low-context distinction. The practical consequence is significant: context becomes something to diagnose at the level of a relationship or task and, within limits, something management can design. The question is no longer whether a company is ‘high’ or ‘low’ context, but which coordination pattern fits which work.

Model
In this series, Model names the editorial family primarily used to understand and explain communication: theories, frameworks, effects, traditions, principles and other conceptual resources. It is an umbrella for a route into the field, not a claim that every included object is a predictive model.
Editorial orientation · Category
Analytical Frameworks, Typologies & Heuristics
Organizes dimensions, distinctions, types or questions so that a situation can be examined systematically. A framework supplies structure, a typology distinguishes forms, and a heuristic offers a usable way to orient judgment.
