Australian-founded data centre giant AirTrunk has unveiled plans to invest around A$43 billion in Japan, dramatically expanding its computing capacity as artificial intelligence drives unprecedented demand for digital infrastructure across Asia.
The Blackstone-owned company plans to more than double its Japanese data centre capacity to more than 1 gigawatt, strengthening its position in one of Asia’s largest cloud and artificial intelligence markets.
The commitment follows AirTrunk’s recent announcement of approximately A$30 billion of investment in India and demonstrates the scale of capital now flowing into infrastructure required to support AI models, cloud computing and digital services.
AI infrastructure race accelerates
AirTrunk was founded in Australia and has grown into one of the Asia-Pacific region’s largest hyperscale data centre operators.
Blackstone and the Canada Pension Plan Investment Board acquired the company in 2024 in a deal valuing it at roughly A$24 billion.
Japan offers a combination of large technology customers, reliable infrastructure and strong demand for cloud services, although access to electricity and suitable development sites remains a significant constraint.
AirTrunk chief executive Robin Khuda has argued that governments able to provide regulatory certainty and faster infrastructure approvals will be best positioned to attract the next generation of AI investment.
The scale of the Japan commitment provides another indication that the AI boom is becoming an infrastructure story as much as a software story.
Building the computing capacity required for advanced models demands enormous investment in electricity networks, fibre connections, land and cooling systems.
AirTrunk’s latest expansion also provides a striking comparison with Australia, where developers increasingly face community opposition, grid constraints and debate around the energy and water requirements of new data centres.
