Murakami, Japan: Submarine Cable Landing Point

Murakami is a landing point located in Japan that serves as a terminus for submarine cable infrastructure connecting points along the Japanese coastline. As a country with 51 submarine cables landing across 68 landing points, Japan maintains one of the most extensive submarine cable networks in the Asia-Pacific region. Murakami contributes to this network as the landing site for one submarine cable, the Awashima-Murakami system, which links two points within Japan itself.

The Awashima-Murakami cable represents a domestic, intra-country connection, placing Murakami within the category of landing points that serve regional Japanese connectivity rather than intercontinental corridors. With a single cable landing here, Murakami functions as a terminus node rather than a multi-cable hub, supporting inter-island or coastal domestic links within the Japanese submarine cable graph.

Cables Landing at Murakami

Awashima-Murakami is a submarine cable with a length of 66 km, with a ready-for-service (RFS) date of 2022, currently listed as draft status. The cable connects two landing points within Japan, running between Awashima and Murakami. Its short length is consistent with a domestic inter-island or coastal route rather than a long-haul international system. No additional technical specifications, such as capacity or fiber pairs, are available for this cable.

Regional Context

Among the submarine cable landing points in Japan, Murakami hosts a single cable, placing it at the lower end of the national distribution when compared to major hubs such as Shima, which serves 12 cables, Maruyama with 9 cables, and Chikura with 8 cables. Landing points such as Hachijo, Minamiboso, and Naha each host 4 cables, illustrating that Murakami, with one cable, represents a more specialized or smaller-scale node within Japan's overall submarine cable geography. Murakami ranks within the top 68 percent of Japan's 68 landing points by cable count.

Network Role

Murakami functions as a single-cable terminus within Japan's domestic submarine cable network. The Awashima-Murakami system, at 66 km in length, enables connectivity between Awashima and the Murakami landing point, supporting a localized domestic corridor rather than a broad international or intercontinental route. As a draft-status cable with an RFS year of 2022, the system represents a relatively recent addition to Japan's submarine infrastructure.

Within Japan's broader submarine cable graph, Murakami occupies a modest but defined position as a domestic endpoint. Its role highlights the diversity of Japan's landing point network, which spans both major international hubs handling transoceanic traffic and smaller domestic nodes like Murakami that serve shorter, intra-national routes between the Japanese islands and coastline.
