Network as good as in the vicinity of Tokyo, with cutting-edge facilities

The "Fukushima Shirakawa Data Center" commenced operations in Shirakawa City, Fukushima Prefecture, which is located on the border with Tochigi Prefecture, in the southern part of the Tohoku region. It is an environmentally-friendly large-scale Data Center that combines the latest outdoor air conditioning and water-cooled air conditioning systems utilizing the cool climate.
We have adopted a modular approach that allows construction according to demand and an advanced air conditioning system.

The network is at the level similar to that in the suburbs of Tokyo. With latency (communication delay) of 3.5 milliseconds from the Tokyo metropolitan area, sufficient response can be obtained.

Won the Good Design Award in 2015

Fukushima Shirakawa Data Center won the Good Design Award for its thorough design of a special building type and for its design that perfectly embodies engineering.

Data Center that Provides New Value

Large suburban type data center in the East Japan area

A building, or a module, is built according to demand in the large area of 67,600 square meters totally. We are committed to provide you stable and high-quality infrastructure platform.

More than 90% of annual air conditioning can use outdoor air cooling

Simulations of temperature, wind speed, and atmospheric pressure were conducted based on operational experience at the Asian Frontier. The building shape and air conditioning facilities have been thoroughly reviewed to ensure that more than 90% of the annual load on the outside air can be used.

Closed network between services, connecting providers

Closed network between services, connecting providers

Depending on what for and how your system is used, you can have closed network to major cloud providers or non-IDCF data centers, connection to major domestic internet exchange points (IXs), and/or mutual connections with on-premises. Complicated tasks such as operation of systems requiring heavy traffic streaming or configuration of hybrid systems with on-premises or multicloud are easliy done.

Ideal for disaster recovery demand

Comparison of earthquake probability in Fukushima Shirakawa DC Area and Tokyo, Nagoya and Osaka

In addition to physical data distribution, such as backup sites and Data Center redundancy, this location, which is considered to have a very low probability of a major earthquake occurring in Japan, also helps to reduce the risk in the event of a major disaster by enabling power suppliers to be diversified.

Data Center without the necessity of entering

When you use the Data Center, we will take care of burdensome relocation and operations, and work that needs to be done in the Data Center. We will reduce the burden on our customers.


Better understanding of Fukushima Shirakawa Data Center

I'm worried about the latency (round trip time of communication between locations). Isn't there any problem in response?
Image of the base configuration within 10 milliseconds from Tokyo or Osaka

The latency between Tokyo and Fukushima Shirakawa Data Center is around 3.5 milliseconds.
In general, the delay is proportional to the physical distance between locations: around 10 milliseconds between Tokyo and Osaka, 15 milliseconds between Tokyo and Hokkaido/Kyushu, and around 35 milliseconds between Tokyo and Okinawa. (according to our investigation)
Delays are minimized by designing optical fiber for the shortest route from Tokyo to Fukushima Shirakawa.

Fukushima Shirakawa is far from the Tokyo metropolitan area. What should we do in case of emergency?

Many customers rarely visit the Data Center during the operation phase after the start of use.
You can rest assured that the Data Center staff of IDC Frontier can take care of everything from introduction and server configuration to emergency operations.

No need to enter the Data Center! Freedom from care by the point system/provision of a camera server as standard

There is no disaster recovery (DR) better than diversification!

More and more customers are choosing the Fukushima Shirakawa Data Center because they feel it is a good location away from the Tokyo metropolitan area.
The Fukushima Shirakawa Data Center is powered by Tohoku Electric Power, enabling power supply to be differentiated from other power companies such as Tokyo Electric Power and Kansai Electric Power.

What companies are using the Data Center?

The Data Center is used by customers in a variety of industries, including enterprise companies, government agencies, and Web service operators.
The Fukushima Shirakawa Data Center is also one of the delivery points for the IDC Frontier cloud services. Therefore, there are many cases where customers who used a cloud at the time of startup have shifted to the use of the Data Center in consideration of costs and usability after the expansion of services and increase in the number of virtual machines.
Regardless of usage applications and scales, we place top priority on peace of mind and create an environment that satisfies customers. We look forward to serving you.


Access management

High security is offered by employing the two-factor authentication, a combination of contactless IC cards and biometric authentication.

Intrusion prevention

Turnstiles prevent unauthorized entry such as tailgating, and all entries and exits are logged.

High capacity power

Main and backup power supply systems. For emergency, uninterruptible power supplies (UPSes) and gas turbine-based power generators, which can run with stockpiled fuel for 48 consecutive hours, are fully equipped.
