Amazon Web Services will build a 420 Tbps subsea cable connecting the United States and Japan, scheduled to begin commercial operations in 2029.
The system, named Sta’O’Nuk, will run 20 fiber pairs across the Pacific Ocean, linking a new landing station in Washington state to an undisclosed site in Japan. It represents the first international subsea cable to land in Washington state in nearly three decades.
Landing station and tribal partnership
AWS partnered with Toptana Technologies to develop the American cable landing station and backhaul network in Ocean Shores, Washington. Founded in 2022 by the Quinault Indian Nation, Toptana is the only Indigenous-owned cable landing station operator on the US West Coast.
Construction has begun on the Ocean Shores facility, designed to support up to four subsea cable systems. Assured Communications serves as program manager and operational service provider for the station, while the Quinault Indian Nation granted AWS permission to use the name Sta’O’Nuk, which translates to “lightning serpent” in the Quinault language.
Washington state last saw international subsea arrivals in 1999, when Pacific Crossing-1 landed at Harbour Pointe and Alaska United East connected in Lynnwood. Toptana previously outlined a 17,700-square-foot, 1 MW station footprint when it first announced site plans in 2022.
Transpacific cloud capacity
Hyperscale cloud providers have shifted from purchasing capacity on shared consortium routes to financing and constructing dedicated private pipes across Asia-Pacific corridors. Direct cable ownership provides AWS with lower latency, predictable operating costs, and dedicated bandwidth between its data center regions in North America and East Asia without reliance on third-party commercial carriers.
The Japanese landing location and local terminal partners remain unannounced as construction advances toward the 2029 target.
