Kitadaito is a submarine cable landing point located on Kitadaitōjima, an island in the village of Kitadaitō, Shimajiri District, Okinawa Prefecture, Japan. As an island community, its connectivity to the broader Japanese telecommunications network depends on submarine cable infrastructure. Two submarine cables land at Kitadaito, both operating entirely within Japanese territorial waters and providing intra-national rather than intercontinental connectivity.
The two cables landing here — Kitadaito Island and Daito Loop — together form a domestic inter-island corridor linking Kitadaitōjima with other points within Japan. Both cables are among Japan's newer additions to the country's submarine cable network, with ready-for-service dates in 2022 and 2025 respectively. This pairing of cables represents a relatively focused, domestically oriented landing point designed to serve the specific connectivity requirements of this remote island community.
Kitadaito Island is a domestic submarine cable with a length of 410 km, with a ready-for-service date of 2022. Its other endpoints are located within Japan, making it an entirely intra-national link. The cable connects Kitadaitōjima to other Japanese landing points, providing the island with a substantial submarine cable link to the mainland or nearby island infrastructure.
Daito Loop is a shorter domestic submarine cable measuring 18 km, with a ready-for-service date of 2025. Like the Kitadaito Island cable, its endpoints are confined within Japan. At 18 km, the Daito Loop is a comparatively short system, suggesting it serves as a local inter-island loop connecting nearby island communities within the Daito island group.
Within Japan's submarine cable landscape of 51 cables across 68 landing points, Kitadaito ranks in the top 90% of Japanese landing points by cable count, hosting 2 cables. This places it well below major Japanese hubs such as Shima (12 cables), Maruyama (9 cables), and Chikura (8 cables), and also below mid-tier landing points such as Hachijo, Minamiboso, and Naha, each hosting 4 cables. Kitadaito's profile is consistent with a remote island landing point serving local connectivity needs rather than functioning as a major international gateway.
Kitadaito serves as a two-cable domestic landing point, enabling inter-island submarine connectivity within Japan for the Kitadaitōjima community. The Kitadaito Island cable, at 410 km, provides the primary long-distance domestic link, while the shorter Daito Loop at 18 km appears to serve local intra-island group connectivity. Together, these two systems ensure that Kitadaitōjima has redundant submarine cable access within the domestic Japanese network.
Both cables carry recent RFS dates — 2022 and 2025 — indicating that Kitadaito's submarine cable infrastructure represents modern additions to Japan's broader network. In the regional submarine cable graph, Kitadaito occupies the role of a dedicated island-access landing point, ensuring that a geographically isolated community in Okinawa Prefecture maintains robust domestic submarine cable connectivity.
