Top Colocation Providers in Japan for Cloud Infrastructure

Over the past few years, Japan has emerged as one of the fastest-growing data center markets in the Asia-Pacific region. With the increasing shift toward cloud hosting, AI-driven applications, and enterprise-grade server deployments, the demand for reliable, secure, and high-performance colocation services in Japan has skyrocketed. According to recent industry reports, Japan’s data center market is expected to cross USD 20 billion by 2027, driven largely by hyperscale cloud expansion and the country’s strong regulatory ecosystem.

Another major trend contributing to this growth is the rising adoption of hybrid cloud infrastructure. More than 65% of enterprises in APAC now prefer combining public cloud with colocation for greater control, cost-efficiency, and compliance. And for global businesses, Japan continues to stand out for one major reason — world-class connectivity and some of the most advanced colocation providers in the world.

In this blog, we explore the top colocation providers in Japan for cloud infrastructure, understand what makes them ideal for cloud hosting workloads, and help you make an informed decision if you're planning to deploy your server or hybrid cloud architecture in Japan.

Why Japan Is a Strategic Hub for Cloud-Focused Colocation

Before diving into the top players, it’s important to understand why Japan has become a preferred location for cloud infrastructure deployment.

1. Excellent Network Connectivity
