Based on the analysis of statistical and information sources, academic publications, and the authors’ personal experience, the article analyzes the peculiarities of Japanese minimarkets that rank among amazing Japanese inventions, creations, and practices and have become an integral part of the Japanese way of life and a trademark of the country. In the academic literature, there have been no comprehensive works focused on this phenomenon so far, and their regional peculiarities, especially the geography of stores operated by different chains, are almost completely neglected. The purpose of this article is to highlight the key academic discourse, to characterize the unique character and universality, which, in fact, constitute the phenomenon of konbini, as well as to identify their regional features. The study clearly shows that these stores, which came to Japan from the United States in 1973, have been completely transformed and are constantly evolving, changing the store concept and presenting a globally unique phenomenon. It describes the characteristics of the leading chains of these stores in their endeavor to gain even greater popularity among consumers and the innovations that have emerged in recent years, including those caused by the COVID-19 pandemic. Studying the phenomenon of konbini, the authors, on the one hand, note their transformation into an important element of social infrastructure, that meets the needs of modern society and is especially necessary in the context of rapidly progressing aging of the population, and, on the other hand, their certain negative impact, especially on the younger generation. The paper features an analysis of the regional characteristics of these stores and the cartographic material illustrating them. It is revealed that, within prefectures, the location of konbini correlates with the number of inhabitants (the number of stores is proportional to the population of municipalities), and each of the 20 konbini chains operating in Japan is located in its own specific area. The authors conclude that konbini facilitate the development of the country’s regions as a whole, and their role in Japanese society cannot be overemphasized. The Japanese experience can be relevant to other countries, including Russian chain stores
