Airtrunk: OSK1 Osaka West Data Center

OSK1 Osaka West Data Center, operated by AirTrunk, is a hyperscale-grade facility located in the western Osaka region of Japan — one of the country’s fastest-growing digital and cloud infrastructure hubs. Purpose-built to meet the needs of hyperscale, enterprise, and AI-driven workloads, OSK1 is part of AirTrunk’s Japan expansion strategy, complementing its existing Tokyo site (TYO1) and strengthening its presence across Asia-Pacific.

The site provides critical geographic diversity from Tokyo while maintaining low-latency connectivity to major Japanese network routes, international cables, and regional cloud availability zones. OSK1 plays a pivotal role in supporting Japan’s cloud ecosystem, delivering massive scale, operational resilience, and sustainability in one of Asia’s most connected markets.
