AirTrunk plans to invest an additional $1 billion to expand its Inzai data center campus in Japan and deploy liquid cooling for high-density AI workloads. The expansion will be funded by a $1 billion green loan led by Sumitomo Mitsui Banking Corporation, MUFG Bank, and United Overseas Bank.
AirTrunk's CEO, Robin Khuda, said that the campus - dubbed TOK1 - is likely to be the first in Japan able to host large-scale AI deployments. He added: "Due to geopolitical reasons, we are seeing more and more customers looking to Japan from a North Asian perspective."
The investment will bring AirTrunk’s total Japanese investment to $9 billion. The company targets $27bn-$30bn in investment over five years and plans to grow its Japan capacity from 530MW to more than 1GW.
Founded in 2018, AirTrunk was acquired by Blackstone and the Canada Pension Plan Investment Board for $16.1bn in 2024. It operates or is developing campuses across Australia, Singapore, Hong Kong, Malaysia, and Japan. Earlier this year, AirTrunk entered India by acquiring Lumina CloudInfra. In July, it secured $2.3bn in funding for its Johor Bahru campus in Malaysia.
