AirTrunk OSK2 Infrastructure in East Osaka
Status: Live / Operational (Initial Phase) | Location: East Osaka, Kansai Region, Japan
Project Overview
The official commissioning of AirTrunk OSK2 in December 2025 marks a massive strategic victory for the Australian hyperscale giant in the Japanese market. Located in East Osaka, OSK2 is a purpose-built 110 MW facility designed to provide regional diversity to the Kansai area, complementing the existing OSK1 site in West Osaka. This launch is a cornerstone of AirTrunk’s broader mission to scale its Japan footprint to over 530 MW, making it one of the largest non-domestic operators in the country. Advanced Cooling for the Generative AI Surge
OSK2 is not merely a capacity play; it is a specialized response to the 2025 surge in Generative AI adoption across Northeast Asia. To accommodate the latest generation of NVIDIA Blackwell and Hopper-based GPU clusters, AirTrunk has deployed a hybrid cooling architecture. The facility is equipped with Direct-to-Chip Liquid Cooling capabilities, allowing it to manage the extreme thermal loads produced by 70kW+ racks. This high-density engineering enables OSK2 to achieve an industry-leading PUE of 1.15, ensuring that massive AI workloads can be processed with minimal energy waste a critical factor given Japan's stringent energy efficiency targets. Regional Resilience and Connectivity
By establishing a major presence in East Osaka, AirTrunk provides much-needed geographic redundancy for global cloud service providers (CSPs) who have historically been concentrated in Tokyo. OSK2 acts as a high-speed gateway, connecting the Kansai region directly to global digital markets via subsea cables landing in the nearby Shima and Toyohashi stations
