This map is designed to keep track of the fictional story locations used in Enstars stories, by placing them as close to their real-life equivalents as possible; this map does not cover Okinawa's cities, features, and geography broadly. Additionally, location placements on my map are not necessarily 1:1, and are instead estimations or compromises. Use the links below to learn more about the real places these locations may be based off.
As I am not from Okinawa, these are educated guesses, so I welcome feedback through email or inbox in how to improve it.

Contextualizing Minimization and Ambiguous Sizing
For narrative convenience, Ensemble Stars's stories scale the distances between locations down to about 10% the size of real-world Okinawa so that characters can move around the story more easily. However, this treament is unique to Okinawa: it is not implemented for the other locations the characters traverse in the game. Ensemble Stars would have you believe Okinawa is a region small enough to walk from place to place comfortably, but Okinawa is quite large and topographically diverse.
Japan is no stranger to treating the location and size of the Ryukyu Islands as malleable and vague; in doing so, administrations can morph Okinawa's borders to suit various narratives that benefit the mainland in political contexts. Politicians and bureacrats treating Okinawa as small and inordinately close to Asia allows for them justify the use of Okinawan land as a satellite military outpost. Conversely, by treating Okinawa as too far from the mainland, Okinawa gets fetishized as a "small, remote island," which helps bureacrats justify the mainland watching over and managing it (as it is far from "civilization").
By choosing to portray Okinawa as a small and easily traversable archipelago, Ensemble Stars inherits the bias of guesstimating and minimizing Okinawa's size. Mapping the locations Ensemble Stars uses proposes a form of Okinawa that is scaled-down, so this context is essential in order to avoid perpetuating the idea of an amorphous and minimized Okinawa. The map on this website shows Okinawa to scale, and places where those locations would actually be if faithful to reality.
