Okinawa Cellular Cable

Okinawa Cellular Cable is a submarine cable system operating within Japan, with landing points at Kagoshima, Nago. It provides dedicated submarine fiber capacity between these locations, supporting telecommunications, internet access, and enterprise connectivity. 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.
