Securitized Etiquette: How Intercoms Reshaped Domestic Interaction in Modern Japan

Scholarship on security technologies has focused on states and infrastructures, but this article shows how security logics reshaped everyday manners inside the home. Introducing the concept of "securitized etiquette," the article examines how video intercoms transformed domestic interaction in modern Japan. Situating contemporary practices within a longer history from the Meiji period to the present, it traces a shift from a "voice-calling culture" (koe o kakeru bunka) to technologically mediated interaction governed by logics of security and risk. By focusing on the materiality of manners, the article highlights domestic technologies as active participants in the reconfiguration of social relations and everyday governance.
