The "MW, all listings" tile above is a wider measure (every tracked site that reports MW, any status, unverified directory listings included), so it is larger than Total listed.
Broker lease rates (CBRE/JLL): available on paid plans. Asking base rent per kW of critical IT capacity. Electricity is normally billed separately (metered pass-through), plus cross-connects and one-time fees. Signed deals, term and size change the number.

The top five operators—Equinix (14 sites), NTT DOCOMO BUSINESS Data Centers (9), NTT-ME Data Centers (8), NTT (6), and Telehouse (6)—control substantial infrastructure but fragmentation remains: no single operator holds more than 3.5% of tracked capacity.
This combination signals tight power availability relative to demand; new capacity additions face supply-side friction from grid limitations and utility interconnection timelines. Sites considering expansion or entry should expect protracted power supply negotiation and potential delays in achieving full operational capacity.
Keppel DC REIT completed acquisition of two hyperscale colocation facilities in Tokyo for $1.2B, consolidating regional hyperscale presence. STTGDC secured $588M in debt financing (announced October 2026) for a 70 MW campus fit-out and operations. AirTrunk announced $1B equity investment in Japan (October 2026) alongside a parallel $1B development program for a campus in Inzai, signaling confidence in long-term regional expansion despite near-term power supply headwinds.
