Building 1 of Canon IT Solutions' West Tokyo data centre holds 2,300 racks in 16,964 m2, and the site's second building adds 2,880 more - 5,180 racks across 33,703 m2 in Nishitokyo, on the firm ground of the Musashino Plateau about 20 km from central Tokyo and away from the major rivers. Density is the selling point: liquid-cooled configurations go to 100 kW per rack, delivered through cooling distribution units with redundant piping so that a failure is contained within one rack. Design PUE is 1.4. Each building takes two independent power feeds, floors bear 1.5 tonnes per m2, and the structure combines base isolation with vertical damping to hold computer-room floor acceleration below 250 cm/s2. Canon ITS rates the facility Tier 4 against the Japan Data Center Council's facility standard, a Japanese scheme rather than an Uptime Institute award. Published marks run to ISO/IEC 27001, ISO/IEC 20000, ISO 22301, ISO 14001, PCI DSS, a SOC 2 Type 1 report and compliance with the FISC guidelines, and the Tokyo Metropolitan Government recognised the site as a top-tier greenhouse-gas performer in 2025.

Frequently asked questions

What rack density does the West Tokyo data centre support?

Up to 100 kW per rack on direct liquid cooling, delivered through cooling distribution units with redundant piping so a fault is isolated to a single rack. Design PUE is 1.4.

How many racks does Canon ITS run at Nishitokyo?

5,180 across the two buildings - 2,300 in Building 1 and 2,880 in Building 2 - within 33,703 m2 of gross floor area.

What does the Tier 4 rating on the West Tokyo site refer to?

The Japan Data Center Council's facility standard, which Canon ITS applies to the building. It is a Japanese scheme with its own criteria and its own audit, and it is a different thing from an Uptime Institute Tier IV award.

How is the Nishitokyo building protected against earthquakes?

Base isolation at the foundation plus vertical damping, engineered to keep floor acceleration in the computer rooms below 250 cm/s2, on Musashino Plateau ground chosen for stability. Floor loading is 1.5 tonnes per m2.
