APAC data center firm AirTrunk is expanding its footprint in Japan with a new campus in Osaka.

The company this week announced plans to develop its second hyperscale data center in Osaka, OSK2.

Located in East Osaka, OSK2 will deliver up to 100MW of total campus IT capacity. OSK1, located in West Osaka, offers 20MW.

Timelines for delivery weren't shared.

Robin Khuda, founder & CEO of AirTrunk, said: “Japan plays a pivotal role in AirTrunk’s platform growth across Asia-Pacific. As Japan’s cloud and AI adoption accelerates, our continued investment in Osaka and Tokyo reflects our long-term commitment to building the scalable infrastructure that underpins this transformation. Japan is not only a key market for us, but a partner in shaping the future of hyperscale and AI innovation. AirTrunk’s Japan investment is one of the largest investments by an Australian company and brings Australia closer to Japan.”

The company said the move will take its total capacity in Japan to 530MW. AirTrunk has invested some $1.57 billion (JPY244 billion) in the country to date.

AirTrunk country head, Japan, Nori Matsushita, added: “OSK2 represents a significant milestone in our commitment to Japan. By expanding in Osaka, we’re not only meeting the growing demand for hyperscale and AI infrastructure, but also creating new opportunities for local talent, suppliers, and communities. This investment strengthens Japan’s position as a digital leader in Asia-Pacific and ensures our customers have the resilient, scalable capacity they need to innovate.”

Founded in 2018, AirTrunk was acquired by Blackstone and Canada Pension Plan Investment Board for US$16.1bn last year in what was the largest-ever deal in the space at the time.

AirTrunk has data center campuses in operation and development in Sydney (x3) and Melbourne in Australia, as well as Singapore; Hong Kong; Johor, Malaysia; Tokyo (x2), and Osaka, Japan.

The company said OSK2 will be its 14th data center, taking its total capacity to more than 2GW.

After announcing plans in October 2023, ground was broken on OSK1 in February 2024. The 16,500 sqm (177,605 sq ft) building will offer 5,400 sqm (58,125 sq ft) of technical space and feature an on-site substation. The company said the facility will service a new major cloud availability zone
