AirTrunk expands in Japan with new data centre development in Osaka

OSK1 will be AirTrunk’s third data centre in Japan and first outside of the Tokyo region

Asia Pacific & Japan (APJ) hyperscale data centre specialist, AirTrunk is rapidly expanding its hyperscale data centre platform in Japan with the announcement of its first data centre development in Osaka.

Scalable to over 20 megawatts (MW), AirTrunk OSK1 (OSK1) is strategically located in west Osaka and will provide regional diversity in a new major availability zone, complementing the company’s existing Japan data centres in east and west Tokyo.

Collectively, AirTrunk will offer more than 430MW of capacity across its three data centres in the country, servicing some of the world’s largest technology companies.

AirTrunk Founder & Chief Executive Officer, Robin Khuda, said: “A surge in artificial intelligence applications and enterprise cloud adoption is driving huge demand for critical digital infrastructure in key markets across Japan.

“The addition of OSK1 to our portfolio will firmly cement AirTrunk as a trusted market leader in hyperscale data centres and demonstrate our unwavering commitment to supporting Japan’s digital future. AirTrunk’s data centres, strategically located in Japan’s two primary hubs in Tokyo and Osaka, are enabling our large cloud customers to scale in the region,” Mr Khuda said.

OSK1 will be powered by a dedicated onsite 77kV substation, improving both reliability and efficiency. In line with AirTrunk’s commitment to Net Zero by 2030, the new data centre is designed to an industry low power usage effectiveness and offers renewable sourcing options to customers.

AirTrunk Head of Japan, Nori Matsushita said: “In less than two years, we have opened two hyperscale data centres and today announce a third development in Japan. As we expand our platform beyond Tokyo into another primary data centre hub in Osaka, we will continue to deliver digital infrastructure that is both scalable and sustainable.”

“The development and ongoing operations of OSK1 will have a positive impact on the local economy, generating new jobs, enabling public cloud growth, fostering sustainable innovation, and contributing to the local community.” Mr Matsushita said.

OSK1 will be financed through the company’s incremental sustainable financing in Japan, maintaining AirTrunk’s linkage to ESG across all its financing platforms.

The facility will be the company’s 11th data centre in the APJ region that also includes data centres in Australia, Hong Kong, Singapore and Malaysia. Collectively the platform will offer more than 1.4 gigawatts (GW) across the region.

The announcement follows AirTrunk’s recent new development announcements, HKG2, its second data centre in Hong Kong, and JHB1 in Johor Bahru, it’s first in Malaysia.
