Osaka, Japan - December 17, 2025 - Asia-Pacific hyperscale data centre operator AirTrunk has announced plans to develop a new 100 MW data centre campus in Osaka, expanding its footprint in Japan as cloud and AI infrastructure demand continues to accelerate across the region.
The project, known as OSK2, will be located in East Osaka and will complement AirTrunk’s existing OSK1 facility in West Osaka, which currently delivers 20 MW of capacity. Once fully built out, the new campus will lift AirTrunk’s total capacity in Japan to around 530 MW, strengthening its position as one of the largest hyperscale platforms in the country.
AirTrunk said the Osaka expansion forms part of a broader investment programme in Japan valued at approximately USD 8 billion, reflecting sustained demand from global cloud service providers and large enterprises deploying AI-intensive workloads.
The company has already invested more than USD 1.5 billion in the Japanese market to date, with Osaka and Greater Tokyo identified as priority regions due to connectivity, power availability and proximity to major enterprise customers.
The OSK2 campus is designed to support high-density, latency-sensitive workloads, including large-scale AI training and inference. While AirTrunk has not disclosed construction timelines or phased delivery milestones, the company confirmed the site will be developed as a hyperscale campus, allowing capacity to be brought online in stages as customer demand materialises.
Industry observers note that Osaka has emerged as a key secondary hub for hyperscale development in Japan, offering geographic resilience and lower land constraints compared with central Tokyo. Recent investments by global and regional operators underline growing interest in the Kansai region as cloud and AI workloads spread beyond traditional core metros.
With OSK2, AirTrunk’s broader platform will reach more than 2 GW of total capacity across Asia-Pacific and the Middle East, spanning markets including Japan, Singapore, Australia, Hong Kong and Malaysia. The company positions its campuses around large-scale sites, long-term power access and infrastructure designed specifically for hyperscale cloud architectures.
The announcement comes amid intensifying competition among data centre developers in Japan, as hyperscalers race to secure capacity capable of supporting next-generation AI models. Power availability, grid stability and sustainability credentials are increasingly shaping site selection and investment decisions, making large, pre-planned campuses such as OSK2 strategically attractive.
As AI workloads continue to push rack densities higher and increase east-west traffic within facilities, operators are under pressure to deliver scalable capacity quickly while maintaining reliability and performance. AirTrunk’s Osaka expansion signals confidence that demand for hyperscale and AI-ready infrastructure in Japan will remain strong well into the next decade.
