AirTrunk plans additional $1bn investment in data center campus in Inzai, Japan

Company plans to triple overall investment in country to $30bn
AirTrunk is planning to invest a further $1 billion in its data center campus in Inzai, Japan.
As reported by Nikkei Asia, the investment will be used to expand capacity and deploy liquid cooling technology at the campus, thus enabling the running of high-density AI workloads.
To fund this, AirTrunk has secured a $1bn green loan, led by Sumitomo Mitsui Banking Corp, MUFG Bank, and United Overseas Bank, among others.
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 new investment will bring AirTrunk's total investment across its Japan sites to $9 billion. During the next five years, it is targeting between $27bn and $30bn. The company also intends to increase its capacity in Japan from the current 530MW, to more than 1GW.
Founded in 2018, AirTrunk was acquired by Blackstone and the Canadian Pension Plan (CPP) for US$16.1bn in 2024, in what was the largest-ever deal in the space at the time. AirTrunk has data center campuses in operation and under development in Sydney (x3) and Melbourne ( x2 ) in Australia, as well as Singapore; Hong Kong; Johor, Malaysia; Tokyo (x2), and Osaka ( x2 ), Japan.
Earlier this year, the company announced it had acquired Indian operator Lumina CloudInfra, officially marking its entrance into India. It secured $2.3bn in funding for its campus in Johor Bahru, Malaysia, in July.
