AirTrunk — TOK1 AI Expansion (Tokyo)

AirTrunk TOK1 in Inzai, East Tokyo, is undergoing a major expansion in 2026 supported by a $1.24 billion green loan, the largest of its kind in Japan. The project adds over 100 MW of new IT load, bringing the campus’s total capacity to over 300 MW. Designed for high-density AI workloads, TOK1 features advanced cooling systems and is powered by 100% carbon-free energy. This expansion is part of AirTrunk’s broader 530 MW Japanese platform, meeting the critical demand for AI and hyperscale cloud services in the Tokyo metropolitan area.
