Data Center Power Index verdict for Tokyo — the market this facility sits in.
Full DCPI breakdown →DC Hub analyst read on Tokyo — the market this facility sits in (full deep-dive →).
Tokyo's data center market is severely constrained, with 275 tracked facilities delivering 557 MW across a fragmented operator base where no single player controls more than 3.4% of capacity. Equinix operates the largest footprint at 19 MW, followed by its subsidiary Equinix, Inc. at 12 MW and NTT DOCOMO BUSINESS Data Centers at 9 MW, with "Unknown" operators also claiming 9 MW—indicating either opacity in the market or assets in transition. The excess-power score of 19/100 coupled with a constraint score of 61/100 reflects a market where available capacity is severely limited and expansion headroom is minimal. The DCPI verdict of AVOID is unambiguous for acquisition-stage investors. With constraint scoring at 61/100—well above the 50-point threshold where power becomes a deal-breaker—any acquisition targeting greenfield expansion or significant load growth faces structural headwinds.…
