AirTrunk, a hyperscale data centre operator with projects across Asia Pacific and the Middle East, has secured a JP¥191.6 billion (US$1.24 billion) green loan to support the refinancing and continued development of its TOK1 hyperscale data centre campus in East Tokyo.
Structured under AirTrunk’s Green Financing Framework, the loan will refinance existing facilities and fund development capex for the next phases of TOK1. These phases will add additional capacity to the campus, which is already scalable to over 300 MW. AirTrunk recently commenced construction to add over 100 MW of IT load at TOK1 to support near-term customer demand.
“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. AirTrunk has been investing deeply in Japan for this reason – to build the hyperscale platform that will underpin the country’s digital future and connect it to the broader region,” said AirTrunk Founder & Chief Executive Officer, Robin Khuda. “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.”
The financing was led by SMBC, MUFG, Crédit Agricole CIB and Société Générale as Global Coordinators. In total, 12 banks acted as Mandated Lead Arrangers and Bookrunners (MLABs) including all four Global Coordinators plus BNP Paribas, The Chiba Bank, DBS Bank, E.SUN Commercial Bank, Mizuho Bank, Natixis, Oversea-Chinese Banking Corporation (OCBC), and United Overseas Bank (UOB).
Sumitomo Mitsui Banking Corporation General Manager, Global Structured Finance, Takehisa Manabe, said, “AirTrunk’s TOK1 campus represents the scale, efficiency, and innovation required to support Japan’s rapidly expanding cloud and AI ecosystem. SMBC is proud to act as Global Coordinator for this landmark transaction, which demonstrates how green financing can channel capital toward mission critical digital infrastructure while advancing the nation’s GX agenda.”
MUFG Bank, Ltd. Managing Executive Officer, Head of Financial Solutions Group, Daisuke Bito, said, “This financing showcases the important role that financial institutions play in enabling sustainable growth in Japan’s digital economy. As Global Coordinator/Structuring Bank and syndication lead, MUFG strongly shares AirTrunk’s commitment to energy efficiency and long-term investment, which aligns with our priorities in responsible financing, and we are pleased to support the next phase of development at TOK1.”
Crédit Agricole CIB Managing Director, Head of Corporate and Leveraged Finance/Distribution and Asset Rotation, Satoshi Oda, said, “As a global leader in green and sustainable finance, Crédit Agricole CIB is proud to partner with AirTrunk on a project that sets a new benchmark for data centre financing in Japan. The transaction reflects growing investor confidence in high efficiency digital infrastructure that can meet the surging demand for compute capacity driven by AI and cloud technologies.”
Societe Generale Co-head of Infrastructure and Telecom, Media & Technology for Asia Pacific, Eugene Tan, said, “This milestone financing highlights the increasing convergence of sustainability and digital transformation. Societe Generale is delighted to support AirTrunk as it expands TOK1, delivering the resilient and low carbon infrastructure that Japan’s technology sector requires to thrive in the AI era.”
The financing forms part of AirTrunk’s broader investment in Japan and follows the recent announcement of OSK2, the company’s second Osaka hyperscale data centre as well as its new Japan headquarters. With this expansion, AirTrunk’s total investment in Japan has now exceeded US$8 billion (JP¥1.2 trillion) to support existing and planned projects over the coming years.
The financing also supports the government’s Green Transformation (GX) ambitions, which aim to mobilise JP¥150 trillion in public–private investment to accelerate Japan’s decarbonisation and next generation infrastructure. Green and transition finance are central pillars of this strategy.
Japan’s Basic Plan for Artificial Intelligence (2025) identifies hyperscale data centres as essential for national compute capacity, secure data localisation, and safe AI deployment. AirTrunk’s continued expansion directly advances these priorities.
At full build-out, AirTrunk’s four Japan campuses – TOK1, TOK2, OSK1 and OSK2 – will deliver ~530MW of total capacity for cloud and AI workloads, providing one of the largest hyperscale platforms in the country to support domestic and global technology customers.
