Deploying GW-scale infrastructure in Japan through deep regional partnerships that enrich local communities

Raiden plans, engineers and constructs large-scale data center campuses across Japan by putting local alignment first. We work directly with municipalities, community leaders, grid operators and power retailers, and regional vendors from day one, grounded in our core belief that digital infrastructure must be planned to enhance host communities.

This deep partnership creates a more sustainable ecosystem that eliminates development friction, allowing us to deliver GW-scale capacity faster, with complete scalability, global standards and full deployment flexibility from shell to turnkey fit-out.

Why data centers?

Direct economic value for regional communities

Data centers bring modern technology demand directly into regional Japan, creating tangible economic benefits for the towns that host them.

Direct financial investment

Billions of dollars of private capital brought directly into local economies.

Local job creation

Local and regional vendors hired for construction, civil works, engineering, facility management and ongoing maintenance.

New municipal tax revenue

Multi-decade tax payments that go straight to funding local schools, roads, healthcare and public services.

Improved local services

Partnering with cities to support civic projects, local vendor growth and regional workforce training.

Our integrated approach to builds

Complete execution and high-speed modular construction

Raiden is built to deliver large-scale capacity fast. We manage every step of the physical build and interconnection process.

  1. Power interconnection and delivery

    Binding grid interconnection and retailer power supply agreements, backed by early long-lead equipment procurement to guarantee on-time power delivery.

  2. Fast, modular construction

    Facilities deployed with scalable, modular building methods that cut delivery times, control costs and maximise work for regional construction partners.

  3. Fiber and network connectivity

    Direct partnerships with national carriers and regional fiber providers for low-latency, multi-route connections.

  4. Civil engineering and site permitting

    Thorough engineering studies, with environmental and development approvals managed in joint teams for fast, compliant site clearance.

  5. Community engagement

    Early engagement with local communities to establish clear mechanisms and paths for communication.

Case study: GigaStream Toyama

Master-planning a 3.1 GW hyperscale campus in partnership with Nanto City and Toyama Prefecture

3.1GW hyperscale campus, adjacent to one of Japan's most critical backbone grid substations

Raiden partnered early with Nanto City to master-plan a flagship 3.1 GW hyperscale campus situated directly adjacent to one of Japan's most critical backbone grid substations, connecting three 500 kV lines from multiple grids.

By forming a joint municipal task force from day one, we de-risked and secured all key aspects of the project while prioritising Toyama's regional ecosystem at every step: retaining local design firms, civil engineers, regional bank capital, general contractors and power subcontractors.

Officially designated as a METI Green Transformation (GX) Strategic Zone (Data Center Cluster Type), GigaStream Toyama proves how early local partnership accelerates development timelines, ensures grid harmony and converts massive digital demand into direct economic value for host communities.
