A new system module building has been opened in response to growing demand, in addition to Japan's first containerized data center facility with outside-air cooling systems!
As a cloud-services base for western Japan, the facility supports disaster recovery efforts.
IIJ Matsue Data Center Park was opened in Matsue-shi, Shimane Prefecture, in April 2011 as a major hub for IIJ cloud services. Following the initially opened Site 1, Site 2 was opened in November 2013 on property adjacent to Site 1. The two sites are the same size. In June 2025, a system module building was opened. It will be used as facility accommodating equipment for the provision of our services, such as cloud and security services, while responding to the growing demand for IT services generated by businesses.
This data center features IZmo and co-IZmo/I containerized IT modules and larger system modules which were developed by IIJ leveraging its extensive expertise in data center operations. It provides the same features and reliability as a conventional data center. To ensure a stable power supply, the facility has a redundant power receiving system, emergency generators, and UPS systems. It also has security systems that include intrusion detection and other surveillance camera systems as well as an entry/exit management system.
To address energy issues, we also adopted a type of air-conditioning system that uses outside air to reduce the power consumed by air-conditioning equipment, which accounts for the bulk of data center power usage. In FY2026, we will install a solar power generation system on the system module building, in addition to the system already installed on the administration building and in other places on the premises of the facility. We will continue to enhance our measures to achieve carbon neutrality, including the procurement of electricity from off-site power generation equipment and initiatives to provide electricity that is generated by and stored in data centers to communities.
Main applications
- Site for IT services (cloud, network, security services) that IIJ provides
- Installation of customer-dedicated containers
Main specifications
- Uses containerized data center modules and system modules developed by IIJ
- Realizes energy savings from outside-air cooling systems (developed by IIJ)
- Contributes to carbon neutrality by using electricity derived from renewable sources of energy
About the Matsue Data Center Park name
The naming is a nod to the IT modules being installed in a park-like setting, as opposed to the concrete buildings data centers are conventionally housed in.
