Equinix, NTT and Sakura Plan 2026 IOWN Trial Linking 2 Japan Data Centers for AI

1 articles · Updated · Telecompaper EN · Jun 30

Summary

  • The three companies will start a proof of concept in the second half of 2026 connecting Sakura Internet's Ishikari Data Center in Hokkaido with an Equinix facility in Tokyo.
  • NTT East will provide the link through its All-Photonics Connect service powered by IOWN, testing whether low-latency, high-capacity optical networking can better handle distributed computing and AI workloads.
  • The trial is also meant to assess operational performance between the two sites, offering a real-world test of long-distance data-center interconnection for AI infrastructure in Japan.

Insights

As Tokyo's grid strains under AI, can this new optical network to Hokkaido truly solve Japan's critical data bottleneck?
Will Japan's 'light-speed' network let AI models train across distant data centers as if they were a single supercomputer?
