Okinawa Remote Islands

Okinawa Remote Islands is a domestic submarine cable network within Japan, connecting 9 coastal and island locations including Aguni, Ama, Hateruma, Itoman, Kumejima, and 4 more. The system provides essential telecommunications infrastructure for communities that would otherwise depend entirely on satellite or microwave links. Japan's island geography makes it one of the most cable-dependent nations on Earth, with dozens of domestic submarine systems connecting its archipelago. GeoCables tracks this cable using RIPE Atlas measurements from four probes in Minsk, Almaty, Tbilisi, and Jerusalem, comparing live RTT against historical baselines to catch performance shifts early.
