Miyake, Japan: Submarine Cable Landing Point

Miyake is a landing point located in Japan, serving as a terminus for submarine cable infrastructure that connects within the Japanese archipelago. Two submarine cables land at Miyake, both operating exclusively within Japan, making this a domestically focused landing point rather than an intercontinental gateway. The cables here support intra-national connectivity, linking island communities within Japan's coastal and island chain geography.

The cables landing at Miyake are oriented toward inter-island and regional domestic connectivity. Both the 5 Villages 6 Islands cable and the Izu Islands Cable System connect Japanese endpoints to one another, establishing Miyake as a node within Japan's internal submarine cable network rather than a point bridging international corridors.

Cables Landing at Miyake

The 5 Villages 6 Islands cable has a length of 355 km and reached ready-for-service status in 2019, currently listed at draft status. This cable connects endpoints within Japan, providing a relatively short domestic link across the region it serves.

The Izu Islands Cable System reached ready-for-service status in 1996, making it the earlier of the two cables landing at Miyake. Also connecting endpoints exclusively within Japan, this system has provided domestic submarine connectivity for nearly three decades. No length is recorded for this cable in available records.

Regional Context

Among Japan's 68 submarine cable landing points, Miyake hosts 2 cables, placing it in the lower tier compared to major hubs such as Shima with 12 cables, Maruyama with 9, and Chikura with 8. Closer peers include Hachijo, Minamiboso, and Naha, each hosting 4 cables. Miyake's two-cable profile reflects its role as a specialized domestic node rather than a high-density international landing hub.

Network Role

Miyake functions as a two-cable domestic terminus within Japan's submarine cable graph. Both cables landing here connect Japanese endpoints to one another, meaning the landing point serves the inter-island connectivity needs of Japan's island communities rather than bridging Japan to overseas networks. The Izu Islands Cable System, operational since 1996, and the more recent 5 Villages 6 Islands cable together give Miyake a modest but sustained presence in Japan's domestic submarine infrastructure.

With 51 submarine cables distributed across 68 landing points in Japan, the national network is extensive, and Miyake occupies a supporting role within it, dedicated to domestic island connectivity. Its position as a two-cable landing point makes it a single-purpose node in Japan's broader intra-national submarine cable graph, ensuring that the island communities it serves maintain a dedicated undersea link to the wider Japanese network.
