Ogasawara Cable Network

Ogasawara Cable Network is a submarine cable system operating within Japan, with landing points at Chichijima, Hachijo, Hahajima. 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. This cable is part of GeoCables' continuous monitoring program — RIPE Atlas probes measure latency around the clock, flagging anomalies when RTT deviates significantly from established baselines.
