DC Hub profiles data centers across Japan, with the strongest concentrations in Osaka, Tokyo and Tama. Operators with the most facilities here include Digital Realty, NTT DOCOMO BUSINESS (Data Centers), Equinix, NTT and IDCフロンティア. Osaka and Tokyo have a published Power Index outlook covering power availability and grid context. Digital Realty is listed in Tokyo, Inzai-City and Minoo-Shi. In Osaka, listed operators include NTT DOCOMO BUSINESS (Data Centers), OPTAGE Inc. and カゴヤ・ジャパン株式会社. In Tokyo, listed operators include Equinix, NTT DOCOMO BUSINESS (Data Centers) and Colt Technology Services Group. Markets are ordered by power availability in the Data Center Power Index (DCPI) where a market is scored, then by listed facilities, and the table can be sorted by market name or by that order. Each facility profile covers power, location and operator detail, and each market links to its Power Index and market pages. Entries come from tracked public source records rather than a verified census, so read the list as a guide to where Japan capacity sits, not as a complete tally.
