AirTrunk has announced plans to develop a second hyperscale data centre campus in Osaka, expanding its footprint in Japan as demand for cloud and artificial intelligence infrastructure continues to rise.
The new facility, known as OSK2, will be located in East Osaka and is designed to deliver up to 100 megawatts (MW) of IT capacity. It will complement AirTrunk’s existing OSK1 data centre in West Osaka, which currently provides 20MW, offering geographic diversity and increased resilience across the Kansai region.
With OSK2 included, AirTrunk’s total hyperscale capacity in Japan is expected to reach approximately 530MW. The company estimates its total investment across existing and planned Japanese projects will be around US$8 billion (approximately JPY1.2 trillion) over the coming years.
AirTrunk operates hyperscale data centres across Asia Pacific and the Middle East, supporting large-scale cloud platforms and increasingly compute-intensive AI workloads. OSK2 will become the company’s 14th data centre globally, contributing to a platform that exceeds 2 gigawatts of secured power capacity across six markets.
Since entering Japan, AirTrunk has invested around US$1.57 billion (JPY244 billion), with projects generating employment during construction and ongoing operations, as well as increased engagement with local contractors and suppliers. The company currently employs more than 100 staff in Japan and recently opened a larger headquarters in Tokyo’s Roppongi Hills Mori Tower to accommodate planned workforce growth.
Japan’s expanding hyperscale capacity aligns with broader national digital initiatives, including Society 5.0 and the government’s Priority Plan for a Digital Society, which place cloud computing and AI infrastructure at the centre of economic and public-sector modernisation. Policymakers have identified large-scale, energy-efficient data centres as critical enablers of AI adoption across industry, government and research.
The OSK2 project is expected to support these objectives by providing additional capacity for global technology companies operating in Japan, while strengthening the country’s role as a regional hub for cloud and AI services.
