Send us a Tokyo requirement What to check first

Where the space is

The Tokyo market, district by district.

Central Tokyo

Otemachi, Chuo, Koto and Shinagawa: the carrier-neutral buildings and the JPIX exchange sites, including KDDI Otemachi, NTT DATA Otemachi, Toyosu and Equinix TY2.

Inzai, Chiba

The hyperscale cluster east of the city. MC Digital Realty’s campus reached 100 MW in April 2026, and Equinix TY12x offers up to 54 MW in a seismically isolated building.

West Tokyo, Saitama and Kanagawa

West Tokyo held about 40% of Greater Tokyo’s live supply in 2024. Azure’s Japan East region is in Tokyo and Saitama.

Osaka

The usual disaster-recovery pair for Tokyo, now a full cloud region in its own right.

Before you sign

What buyers overlook in Tokyo.

Data centers are not interchangeable, and the differences usually show up after the contract is signed. These are the checks we run before a Tokyo shortlist.

Power
TEPCO had about 9.5 GW of data center requests by August 2024, mostly within 50 km of Otemachi, and publishes a map of areas where it can connect power faster. New capacity takes years, so energized space is the near-term route.
Earthquakes and floods
Buildings differ: some are base-isolated, some built to the 1981 code, and flood elevation varies by site. We ask for each building’s seismic and flood ratings before a shortlist.
Contracts
Terms are often under Japanese law with the Japanese text prevailing, and exclusive space can be treated as a building lease. We work through the terms with you and the provider before you sign.
Finance and data rules
Financial institutions follow the FISC Security Guidelines (14th edition, March 2026), and Japan’s APPI sets rules for sending personal data abroad. We check which providers support both.
Exchange latency
JPX’s arrownet is about 3 microseconds one way from its co-location area, against about 60 microseconds through an access point, so trading firms need the right building.

How we work

Find it. Contract it. Build it. Manage it.

Take the whole lifecycle or just the stage you need. One lead owns the schedule, the providers and the paperwork, from the first Tokyo requirement to day-two operations.

STAGE 1

Find the right space

A shortlist of Tokyo facilities that fit on power, density, connectivity and price, with site tours and a side-by-side comparison.

STAGE 2

Contract it

Bids leveled and terms negotiated: price per kW, escalators, expansion rights, renewal options and the MSA.

STAGE 3

Build out the racks

Cabinet layouts, PDUs, structured cabling, cross-connects and access control, with every vendor coordinated until go-live.

STAGE 4

Manage it

Remote hands, capacity and invoice checks after go-live, and Portfolio Desk if you run several sites.

Questions

Colocation in Tokyo: common questions.

How much does colocation cost in Tokyo?

CBRE put the average at about US$280 per kW per month in Q1 2026. Keppel, citing industry data, gives JPY 20,500 to 30,000 per kW per month for 2024–25, up from 17,000 to 20,500 in 2021–23. Prices are rising with power costs.

Central Tokyo or Inzai?

Central Tokyo for exchanges, carriers and JPX co-location. Inzai for larger, newer campuses at hyperscale size. Many firms pair a central Tokyo cabinet with capacity outside the city.

Will the contract be in Japanese?

Often, at least in part. Some providers’ English terms state that the Japanese version prevails and that Japanese law applies, so the review has to cover both.

Can financial firms use colocation in Tokyo?

Yes. Most follow the FISC Security Guidelines, and providers such as Equinix list FISC among their Tokyo certifications. We check each shortlisted building.
