Source: DC Hub (dchub.cloud), facility records as of 2026-11-12. Verified sites that report MW only; blank means no MW reported. 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.
DC Hub does not hold a lease-rate figure for this market yet.
Digital Realty is constructing the 24 MW KIX15 facility in Osaka, underscoring continued deployment despite these conditions.
The DCPI verdict of AVOID reflects a supply-demand imbalance on the power side. Together, these metrics indicate that acquiring or building incremental capacity requires negotiating power supply agreements in a market where available grid headroom is limited. No recent tracked deals have materialized in Osaka, suggesting current commercial terms may not align with deployment urgency.
OPTAGE's five-site presence establishes the largest operational footprint, followed by Equinix and NTT DOCOMO BUSINESS at three sites each. The absence of recent deal activity—no acquisitions, stakes, or partnerships recorded—contrasts with broader Japan momentum, where CapitaLand has acquired Osaka data center assets from Mitsui, and Itochu plans ten new facilities nationally by 2030. Kansai, the broader region encompassing Osaka, has emerged as a secondary data center hub as primary markets saturate, yet Osaka itself has not captured corresponding M&A or greenfield announcement volume.
