STACK secures JPY ¥39.7bn green loan for Tokyo data centre

STACK Infrastructure has secured a green financing facility totalling JPY ¥39.7 billion to support the ongoing development of its 36MW TKY01 data centre campus in Inzai, Greater Tokyo.

The funding arrangement will be utilised for the delivery of the 36MW TKY01 site, with the first 18MW building scheduled for completion in 2026 and a further 18MW expansion expected to be available in 2027. The facility received backing from several prominent Japanese and international lenders and was fully underwritten by Natixis CIB and Societe Generale, who also served as green loan coordinators.

Capacity boost

TKY01 is situated on a 5.7-acre site in Inzai, a hub for large-scale data centre projects in Greater Tokyo. The campus is being developed to meet the varying needs of cloud, artificial intelligence, and enterprise clients, featuring advanced security measures, robust resiliency, and AI-ready capabilities. Once fully delivered, the campus will provide 36MW of scalable infrastructure capacity for customers in one of the region's most supply-constrained markets.

According to STACK Infrastructure, Tokyo is regarded as a pivotal digital infrastructure market within Asia. The addition of the TKY01 campus is intended to address the growing regional demand for efficient and reliable digital services, particularly as supply constraints continue in metropolitan hubs.

"This transaction underscores STACK's ability to align with long-term capital partners and deliver sustainable, scalable capacity in Japan. As demand for mission-critical digital infrastructure continues to accelerate across the region, this financing ensures we can expand with scale, speed, and certainty," said Preet Gona, Chief Executive Officer of STACK APAC. 

Green financing

The structure of the green financing facility is designed to embed sustainability considerations within the development and operation of the TKY01 campus. Natixis CIB and Societe Generale, as underwriters and green loan coordinators, worked to ensure the capital aligned with environmental objectives, which is consistent with a broader regional move towards sustainable data centre design and operation.

STACK Infrastructure stated that the sustainability focus of this funding allows the company to expand efficiently in existing and new markets while adhering to environmental guidelines. The company is also moving ahead with additional large-scale developments, including an 80MW campus in Osaka (referred to as KIX01), as well as further projects across Australia and Malaysia.

Regional expansion

Alongside the ongoing Tokyo and Osaka projects, STACK Infrastructure is increasing its footprint within the Asia Pacific market through other significant undertakings. Collectively, these developments aim to strengthen STACK's capacity to serve hyperscale requirements, particularly in locations facing high demand and limited existing infrastructure.

TKY01's phased rollout is expected to address both immediate and future needs as digital transformation accelerates in Japan and the wider region. With security, resiliency, and scalability as core principles of its design, the campus will play a key role in supporting cloud, AI, and enterprise solutions as they expand their operations in Greater Tokyo.

The successful completion of this green financing round reaffirms institutional and lender confidence in STACK Infrastructure's strategic direction within Asia Pacific, as well as its commitment to environmental responsibility in the provision of critical digital infrastructure.
