AirTrunk has secured a JP¥191.6 billion (US$1.24 billion) green loan to refinance and expand its TOK1 hyperscale data centre campus in East Tokyo, marking the largest data centre financing completed in Japan.
The loan, arranged under AirTrunk’s Green Financing Framework, will refinance existing facilities and fund the next development phases of the TOK1 campus. The site is scalable to more than 300MW, with construction already underway to add over 100MW of IT capacity to support rising demand for cloud and artificial intelligence workloads.
The financing was led by SMBC, MUFG, Crédit Agricole CIB and Société Générale as Global Coordinators, with a total of 12 banks acting as Mandated Lead Arrangers and Bookrunners.
“Japan is one of the world’s most important cloud and AI markets, and we’re committed to building the digital infrastructure that enables its long-term growth,” said Robin Khuda, Founder and CEO of AirTrunk. “This landmark financing enables us to accelerate the expansion of TOK1 and continue delivering the capacity our customers need today, while preparing Japan for the extraordinary compute demands ahead.”
AirTrunk said its total investment in Japan has now exceeded US$8 billion (JP¥1.2 trillion), following the recent announcement of its OSK2 hyperscale data centre in Osaka and the establishment of its Japan headquarters.
At full build-out, the company’s four campuses in Japan—TOK1, TOK2, OSK1 and OSK2—are expected to deliver around 530MW of total capacity for cloud and AI workloads.
“This is the largest data centre financing ever completed in Japan and a testament to the deep collaboration between AirTrunk and our banking partners,” said Masato Hori, Associate Vice President Treasury Japan at AirTrunk.
The green loan also aligns with Japan’s Green Transformation (GX) strategy, which aims to mobilise JP¥150 trillion in public and private investment to support decarbonisation and next-generation infrastructure.
