STACK Tokyo TKY01 AI Hyperscale Data Center Campus – 36 MW

Status: Phase 1 Operational / Phase 2 Under Construction   |   Location: STACK INFRASTRUCTURE 1 Chome-2 Hara 270-1335 Inzai

Project Overview

The STACK Infrastructure Tokyo TKY01 Campus represents a strategic $600 million hyperscale digital infrastructure development located in the Inzai District of Chiba Prefecture, Greater Tokyo, one of Japan’s most important data center markets. Encompassing a 5.7-acre campus footprint, the facility consists of two specialized 18 MW data center buildings, delivering a combined 36 MW of gross utility capacity. The campus is purpose-built to address the rapidly increasing demand for cloud computing, high-density artificial intelligence, and advanced digital infrastructure from global hyperscale customers across East Asia.

Designed for Hyperscale and AI Workloads

The TKY01 campus is engineered to support the evolving requirements of hyperscale cloud platforms and high-density computing environments, with its two-building configuration providing scalable capacity for large deployments. The facility’s combined 36 MW utility capacity enables hyperscale customers to accommodate compute-intensive workloads requiring substantial electrical and cooling infrastructure. Its design supports cloud computing, enterprise applications, artificial intelligence training and inference, and other high-performance workloads, positioning TKY01 to serve the growing demand for accelerated computing across Japan and the wider East Asian market.

Large-Scale Infrastructure and Economic Impact

Backed by an estimated $600 million investment, TKY01 represents a significant expansion of digital infrastructure capacity within the Greater Tokyo region. The 36 MW campus provides a scalable platform for global hyperscalers seeking dedicated capacity within Japan’s mature technology ecosystem. Its 5.7-acre footprint and two-building configuration create additional supply for cloud platforms and AI-driven businesses while strengthening Chiba Prefecture’s position as a major data center destination. The development also supports the continued growth of Japan’s digital economy by enabling greater deployment of cloud services, enterprise computing, and high-performance AI infrastructure.

Strategic Connectivity in Greater Tokyo

Located in Inzai, Chiba Prefecture, TKY01 benefits from its position within one of Japan’s most established data center clusters. The location provides access to Greater Tokyo’s extensive telecommunications, fiber connectivity, power infrastructure, and metropolitan network ecosystem, enabling reliable connectivity to major enterprise and cloud markets. Its proximity to Tokyo allows hyperscale customers to deploy infrastructure close to one of Asia’s largest concentrations of businesses and digital users while maintaining access to regional and international network routes. The TKY01 development further strengthens STACK Infrastructure’s presence in Japan and reinforces the Inzai region’s strategic role in supporting the continued expansion of hyperscale cloud and AI infrastructure across the Asia-Pacific market.
