STACK Infrastructure has secured ¥39.7 billion (approximately USD $255 million) in green financing to advance construction of its 36MW TKY01 data center campus in Inzai, Greater Tokyo. The funding, fully underwritten by Natixis CIB and Société Générale, supports the development of one of Japan’s largest AI-ready and sustainability-aligned digital infrastructure projects.
The first 18MW phase of TKY01 is scheduled for completion in 2026, followed by an additional 18MW expansion in 2027. Located on a 5.7-acre (2.3-hectare) site, the campus is engineered for scalability, high resiliency, and security to meet demand from hyperscalers, AI platforms, and enterprise clients. The green financing underscores STACK’s alignment with Japan’s environmental standards and growing institutional confidence in sustainable data center investment.
STACK’s expansion in Japan includes an 80MW campus in Osaka (KIX01) and large-scale projects underway in Australia and Malaysia. The company’s Asia-Pacific footprint continues to expand rapidly as regional cloud and AI workloads drive new capacity requirements across key digital hubs.
