STT GDC’s Tokyo campus comprises TYO1 and TYO2 in Goodman Business Park, Inzai. Its 70.8 MW combined planned IT capacity is not all operating: TYO1 launched in June 2025, while TYO2 targets late-2027 operation. The October 2026 JPY93 billion green loan supports fit-out and subsequent operation of both buildings, not proof of drawn funding. TYO1 has dual 66 kV feeds and closed-loop cooling design. TYO2’s future liquid-cooling provision and TIA-942-C Design and LEED Gold targets do not establish installed systems or achieved certifications. Occupied IT load and lease-title details remain unverified.

JPY93 billion green loan announced October 27, 2026 for TYO1/TYO2 fit-out and subsequent operation. Not capex or operating capacity. Standard Chartered was Lead Coordinator and, with Societe Generale, Green Loan Coordinator. Mizuho Bank, OCBC and UOB supported the financing alongside them; their exact contractual roles are not specified and are mapped as other, not inferred lenders. Societe Generale involvement is retained here, while its structured link is held because two canonical identities exist.
