Colocation Services in Tokyo, Japan

Tokyo sits at the centre of Asia-Pacific digital infrastructure. For US and European companies expanding into APAC, it is the default first market: deep submarine cable density, redundant internet exchange access, a highly skilled local technical workforce, and a legal environment that harmonises cleanly with GDPR through the Japan-EU adequacy decision. The Tokyo metropolitan area is home to more than 60 commercial datacenters operated by global brands including Equinix (TY1 through TY12), NTT Communications (Otemachi campus), AT Tokyo (Koto-ku and Inzai), Digital Realty, and KDDI Telehouse. This density means enterprises can build genuine infrastructure redundancy within a single metro, with primary and secondary sites separated by tens of kilometres rather than hundreds. From a connectivity standpoint, Tokyo provides access to major internet exchanges including JPIX (Japan Internet Exchange), JPNAP (Japan Network Access Point), and BBIX. These exchanges carry the bulk of domestic and international transit traffic in Japan. Enterprises with latency-sensitive workloads, including financial trading, gaming, and content delivery, use Tokyo specifically because sub-millisecond latency to these exchanges is achievable across all major facilities. Tokyo also matters for compliance. Japanese law requires that personal data relating to Japanese residents is either stored in Japan or transferred to jurisdictions with equivalent protections. The EU-Japan adequacy decision under GDPR means European companies can use Tokyo facilities as a compliant data residency node for both inbound Japanese data and outbound EU data. For financial services firms, the Centre for Centre for Financial Industry Information Systems (FISC) standard governs how technology supporting Japanese banking operations must be managed, audited, and documented. Any enterprise planning to serve Japanese financial clients needs FISC-aligned operational practices, not just FISC-certified hardware.

The Tokyo colocation market is dominated by five operators that account for the majority of enterprise-grade capacity. **Equinix TY1-TY12.** Equinix operates the largest campus footprint in Tokyo, spanning twelve facilities across the metro area. TY1 through TY12 offer Equinix Fabric interconnection, direct access to JPIX, and carrier-neutral peering to thousands of networks globally. Power in Tokyo datacenters is delivered at 100V single-phase and 200V three-phase, both at 50 Hz. This is a critical difference from North American standards (120V/60Hz) and European standards (230V/50Hz). Equipment imported from the US may require step-down transformers or power supply swaps prior to racking. **NTT Communications, Otemachi.** NTT's Tokyo datacenters anchor their flagship Otemachi campus in the heart of Tokyo's financial district. NTT's facilities carry FISC certification alongside ISO 27001 and SOC 2 Type II. For enterprises serving Japanese banks or insurance firms, NTT Otemachi is the reference facility in terms of regulatory credibility. **AT Tokyo, Koto-ku and Inzai.** AT Tokyo operates facilities in the Koto-ku district of Tokyo and in Inzai city in Chiba prefecture. AT Tokyo is a Japanese specialist operator with no affiliation to US telecommunications carriers. Their facilities offer direct JPIX connectivity and are well-regarded in the domestic market for power density and physical security. **Digital Realty Tokyo.** Digital Realty operates multiple Tokyo facilities under their global PlatformDIGITAL model. Their Tokyo campus provides FISC compliance, ISO 27001, and access to the PlatformDIGITAL ecosystem of clouds, carriers, and managed service providers. **KDDI Telehouse.** KDDI operates its Telehouse Tokyo facilities with deep integration into KDDI's Japanese carrier network. Telehouse is particularly relevant for enterprises requiring direct interconnects to Japanese mobile and broadband carriers. For most western enterprises, the facility selection comes down to Equinix for global interconnection breadth, NTT for financial services compliance depth, and AT Tokyo for cost efficiency from a proven local operator.

Reboot Monkey is not a colocation provider. We do not own or operate datacenters and do not sell rack space or bandwidth. We are a third-party physical datacenter services company that operates inside customer-chosen Tokyo facilities. When your team colocates servers in Equinix TY3, NTT Otemachi, or AT Tokyo Koto-ku, Reboot Monkey's technicians can be dispatched to your cabinet to perform the physical work your remote team cannot. This is the fundamental distinction between a datacenter operator and a third-party support provider: the operator gives you rack space and power; Reboot Monkey gives you certified hands inside that rack space. Western enterprises expanding into Tokyo face a consistent operational problem. Their IT teams are in New York, Amsterdam, or Frankfurt. When a server goes down at 03:00 JST, nobody is on-site to reboot it, replace a failed drive, or reseat a cable. Reboot Monkey fills this gap with a locally based technician team available around the clock. Our vendor-neutral positioning means we operate across all major Tokyo facilities regardless of which operator your contract is with. If you have primary infrastructure in Equinix TY5 and a disaster recovery site in NTT Otemachi, one Reboot Monkey engagement covers both. This is the operational model that facility operators cannot offer: they are by definition limited to their own buildings. Two specific credentials our team brings to every Tokyo service call: active operations inside Tokyo metro facilities, and documented experience with Japanese datacenter access protocols including FISC-aligned ticketing and photo documentation requirements that financial services clients need for audit trails.

The two most requested on-site services in Tokyo are remote hands and smart hands. They are related but distinct. **Remote hands** covers basic physical tasks: power cycling servers and networking equipment, inspecting indicator lights and reporting status, replacing pre-shipped hardware components, managing cable runs and labelling, and escorting vendor engineers during scheduled maintenance windows. Remote hands tasks do not require deep technical judgement. A competent technician can complete them following written instructions provided by your team. For western enterprises whose Tokyo footprint is largely stable, remote hands is the ongoing support model that keeps operations running without the cost of a full-time local hire. **Smart hands** covers technically complex work: configuring network devices at the CLI level, troubleshooting hardware diagnostics including POST errors and IPMI access, performing OS-level recovery procedures, and coordinating multi-vendor hardware replacements involving Dell, HPE, Cisco, Juniper, and Arista equipment. Smart hands engagements require a technician who can read your runbook and make reasoned decisions on-site when conditions do not match the expected state. In Tokyo specifically, smart hands demand is elevated by two market characteristics. First, the density of high-value financial and trading infrastructure means equipment failures carry significant revenue impact, creating urgency for technically capable on-site response rather than basic break-fix. Second, many western enterprises running equipment in Tokyo also operate across multiple facilities (an Equinix primary site plus an NTT DR site is a common architecture), creating coordination complexity that basic remote hands cannot address. Reboot Monkey handles both service tiers in Tokyo. Our technicians are dispatched with the task brief, facility access documentation, and relevant equipment specifications. All work is photo-documented, time-stamped, and reported in writing. This documentation trail satisfies both internal change management requirements and FISC audit trail standards for financial services clients. See our dedicated pages for [remote hands in Japan](/en/remote-hands/japan/) and [smart hands in Japan](/en/smart-hands/japan/) for full service specifications.

Beyond day-to-day support, Reboot Monkey handles infrastructure deployment projects in Tokyo datacenters. **Rack and stack.** When your enterprise ships new server hardware to a Tokyo facility, it does not arrive pre-installed. The equipment arrives in transit packaging, requires physical inspection, needs to be mounted and cabled in the correct rack positions, and must be powered on and verified before your remote team can take it over. Reboot Monkey manages this complete process: receiving coordination with the facility shipping dock, unpacking and inspection, rack mounting following your cable plan, power cabling to correct PDU positions (100V or 200V as specified), network cabling to your switching infrastructure, and power-on verification. We document each step with photographs submitted to your change management system. For enterprises deploying GPU servers for AI workloads in Tokyo, the rack and stack process involves additional complexity. High-density GPU nodes often exceed standard power draw requirements, require specific rack unit clearances for thermal management, and may need facility pre-approval for power circuit upgrades. Our technicians coordinate these facility-level requirements on your behalf so your infrastructure team in the US or EU can manage the process remotely. **Server migration.** Moving infrastructure between Tokyo datacenters (for example, migrating from an initial facility to a new primary site) is a physically intensive project that most western IT teams cannot execute remotely. Reboot Monkey manages the on-site elements: decommissioning at the source facility, secure transit between facilities within the Tokyo metro, re-racking at the destination, and return-to-service verification. For time-sensitive migrations, we coordinate simultaneous work at both facilities. See our [rack and stack in Japan](/en/rack-and-stack/japan/) page for service scope and lead times.

Two Japanese regulatory frameworks affect how foreign enterprises must manage datacenter operations in Tokyo. **APPI (Act on Protection of Personal Information)** is Japan's primary data protection law. For foreign companies colocating servers in Japan, APPI governs how personal data about Japanese individuals is stored, transferred, and managed. The practical datacenter implication is that physical access to servers containing Japanese personal data must be controlled, logged, and auditable. Reboot Monkey's documentation model, which includes photo records of every cabinet access, timestamped service reports, and complete technician access logs, provides the physical access audit trail that APPI compliance programmes require for hardware-level events. **FISC (Centre for Centre for Financial Industry Information Systems)** sets the technical and operational standards for IT systems supporting Japanese financial institutions. If your Tokyo datacenter infrastructure supports banking, securities, or insurance operations in Japan, FISC standards apply. FISC requires detailed physical access controls, documented change management for hardware work, and specific incident response protocols. The FISC Security Guidelines specify that every physical access to production financial infrastructure must be recorded with identity verification and task documentation. Reboot Monkey's service delivery model was built to satisfy exactly these requirements: every technician is badged into the facility under their own credentials, work is photo-documented against a specific ticket, and reports are delivered to your change management system in a format compatible with FISC audit evidence requirements. For US enterprises, neither APPI nor FISC creates barriers to operating in Tokyo. Both frameworks require operational discipline rather than prohibiting foreign operators. The practical requirement is that whoever performs physical work inside your Tokyo cabinets does so under a documented, auditable process. Third-party providers operating informally or without documentation discipline create compliance risk. Reboot Monkey's structured delivery model eliminates this risk. EU enterprises benefit from the Japan-EU adequacy decision, which means data transfers between the EU and Japan are treated as transfers to an adequate jurisdiction under GDPR, simplifying the legal basis for running EU-data workloads on Tokyo infrastructure.

Tokyo's colocation market is not homogeneous. Three buyer segments drive the majority of enterprise demand from western companies. **Financial services and fintech.** Tokyo is the primary financial technology hub in APAC, home to the Japan Exchange Group and a rapidly growing fintech ecosystem. Western banks and trading firms colocate in Tokyo primarily to achieve sub-millisecond order routing latency to Japanese markets. For these clients, the physical datacenter is the trading infrastructure. Reliability, uptime, and documented change management are not operational preferences but regulatory requirements. FISC applies to any infrastructure that touches Japanese financial market data. Reboot Monkey's documented service model and experience with FISC-aligned ticketing requirements makes us the appropriate operational partner for financial services clients in Tokyo. **Gaming and content delivery.** Japan is among the largest gaming markets globally. Western game publishers and platform operators colocate game server infrastructure in Tokyo to serve Japanese and broader East Asian player bases. Latency performance is the primary requirement: Tokyo-based servers achieve single-digit millisecond round-trips to Korean, Taiwanese, and southeastern Chinese player populations that would require significantly higher latency from a Singapore alternative. Reboot Monkey provides rack and stack, hardware replacement, and smart hands support for gaming infrastructure in Tokyo, including emergency support for critical game launch windows. **Technology companies and SaaS platforms.** Western SaaS companies expanding into Japan require Japanese-resident infrastructure for performance, data residency, and customer trust reasons. Japanese enterprise buyers often require confirmation that their data is stored in Japan. Tokyo colocation provides the infrastructure layer for this requirement. For engineering teams managing Tokyo infrastructure from US or EU headquarters, the need for reliable on-site support across Equinix and NTT facilities is immediate from day one of production traffic.

Tokyo ranks among the more expensive colocation markets in APAC, reflecting land costs, power infrastructure investment, and the premium placed on facilities in the metro. The following ranges reflect general market conditions and do not represent Reboot Monkey pricing (we provide support services, not colocation hosting). **Rack space.** A full 42U cabinet in a Tier III Tokyo facility (Equinix, NTT, Digital Realty) is estimated at USD 800-1,400 per month at standard power densities of 4-8 kW per rack. High-density racks for GPU and AI infrastructure carry a significant premium, reflecting the additional power and cooling infrastructure required. **Power.** Tokyo power pricing is higher than most US markets and broadly comparable to Northern Europe. The shift from standard 100V infrastructure to 200V three-phase delivery for high-density compute is increasingly standard at Equinix TY and NTT facilities for GPU clusters. Enterprises drawing 10+ kW per cabinet should budget for power as a distinct line item. **Cross-connects.** Direct connectivity to JPIX, JPNAP, or BBIX via cross-connect carries a one-time installation fee and a monthly recurring charge per facility. Enterprises with bandwidth-intensive workloads should model interconnect costs as a material component of their Tokyo infrastructure budget. **On-site support.** Reboot Monkey's support services in Tokyo are priced independently of colocation contracts. Remote hands engagements for routine tasks are billed per task or on a retainer basis for enterprises with ongoing monthly support needs. Smart hands and project work (rack and stack, migrations) are scoped and quoted per project. Contact us via [/en/contact/](/en/contact/) to discuss current rates. For enterprises comparing Tokyo against Singapore or Sydney as their APAC primary colocation market: Tokyo carries higher absolute rack costs than both alternatives but offers materially better latency to Northeast Asian markets and a more developed financial services infrastructure ecosystem.

Tokyo is rarely a standalone deployment for western enterprises. Most use it as the anchor for a broader Japan or APAC infrastructure strategy. At the country level, Tokyo is the dominant datacenter market in Japan but not the only one. Osaka is Japan's second market, with a separate power frequency (60 Hz versus Tokyo's 50 Hz), its own colocation facilities, and relevance for disaster recovery. The Tokyo-Osaka geographic separation is the standard enterprise DR architecture in Japan. For enterprises building multi-site Japan infrastructure, Reboot Monkey can support operations at both Tokyo and Osaka facilities under a single engagement. At the APAC level, Tokyo typically connects to Singapore for Southeast Asia coverage, Hong Kong for China access, and Sydney for the Australia and Pacific region. These four cities form the backbone of most western enterprise APAC networks. Reboot Monkey operates across all four markets, which means the same operational model and documentation standards apply consistently across your APAC footprint rather than requiring separate vendor relationships in each city.
