Why prices sit where they do
Tokyo's constraint is land and grid, not only the price of electricity. Expansion increasingly happens at the edge rather than in the wards. Inzai, over the line in Chiba, is that edge: stable plateau ground, land in usable parcels and feeders with headroom, which is why AirTrunk, Colt, Digital Edge, Equinix and other campus operators cluster there. Interconnection did not fully follow them. Carriers, exchanges and the financial cross-connect fabric stay in the central legacy nodes, so the metro sells two products at two prices: rack space where the networks terminate, and megawatts on the Chiba side, joined by dense metro fibre. Published Tier evidence is less common than in some Western markets and should not be inferred from the operator name, so request the current facility design and certificate scope directly.
Frequently asked questions
How much does colocation cost in Tokyo (Inzai), Japan?

Why is colocation priced the way it is in Tokyo (Inzai), Japan?
Commercial electricity in Tokyo (Inzai), Japan is $0.185 per kWh, and power is the largest single input into a colocation rate.
