Colocation providers in Japan

Operators with tracked data centers in Japan, sorted by sites, then published capacity. Sites / operational; MW is the sum of what each operator publishes for these sites. Some entries are hyperscaler or enterprise sites that do not sell colocation — check the facility card.

Colocation markets in Japan

Availability in Japan: what the numbers do and do not say

Published megawatts describe how facilities are designed, not how much power is available to a new customer today. Vacancy is confirmed only in an operator's proposal for a specific hall and ready-for-service date. Where operators have told Coloprice that a market is sold out to a date, the facility cards say so; otherwise assume nothing and ask each provider the same question.

What the colocation price includes — and what it does not

  • Included in the base fee: rack or cabinet space, a committed power circuit, cooling, physical security, and usually a basic remote-hands allowance.
  • Billed separately: metered electricity above the allowance (or a per-kWh rate on retail contracts), cross-connects, IP transit, additional remote hands, and one-off setup or installation fees.
  • Wholesale contracts add annual escalators, ramp schedules and power-commitment minimums; retail contracts add overage rates and bandwidth caps. Compare providers on the same committed kW, density, term and connectivity.

FAQ

Who are the largest colocation providers in Japan?

By tracked sites: Equinix with 17. By published IT capacity: Ada Infrastructure with 601 MW. Facility counts and MW come from operator pages and registries; the table above lists every operator with a tracked site in Japan, including some that do not sell space.

Is there colocation capacity available in Japan right now?

Coloprice tracks 110 facilities here (92 operational, 18 under construction or announced) but does not track vacancy. Availability, rack density and delivery dates are confirmed only in a current proposal for a specific hall — send the same brief to several providers and compare.

How do I get comparable colocation quotes in Japan?

Send every provider one brief: committed kW, density per rack, redundancy, carriers and cloud on-ramps, start date, term and expansion rights. Ask for space, power, metered electricity, cross-connects, installation and remote hands as separate lines, then compare against the Tokyo benchmark. The form below routes one brief to matching operators; no operator pays for position.
