CONCEPT
Pioneering the Future of Digital & Green Society: Next-Generation Data Center
Ishikari Renewable Energy Data Center #1 boldly resolves the complex challenges facing 」apanese data centers,
simultaneously achieving decarbonization and strengthening digital infrastructure.
DC in DC
"Data Center within Data Center" housing multiple data center operators
Each 2nd and 3rd floor are divided into three and six data halls in total, which will be utilized by multiple data center operators. As the building and large-scale equipment are already in place, tenants need only prepare the equipment within the data halls.
RENEWABLE ENERGY
Achieving 100% renewable energy operation with two types of power supply
Ishikari Renewable Energy Data Center #1 will be operated using 100% renewable energy,
primarily produced in Ishikari. The power used in the facility will be generated through on-site PPA*,
with any shortfall supplied by green energy procured by ReENE Co., Ltd (a group company of Tokyu Land Corporation)
* On-site PPA: a method of directly supplying power by connecting user facilities and power plants with private lines.
NETWORK
IOWN®
Ishikari Renewable Energy Data Center #1 will resolve various issues facing remote data centers by the
implementation of IOWN®, promoted by the NTT Group.
* IOWN® is a trademark or registered trademark of Nippon Telegraph and Telephone Corporation (NTT).

IOWN®: Aiming for Optical Connectivity from Networks to Devices
IOWN® is a next-generation communication infrastructure concept promoted by the NTT Group. By implementing cutting-edge technology known as the All-Photonics Network (APN), it enables end-to-end photonic transmission across the network, thereby realizing high-capacity, low-latency, and low-power-consumption data communication.
※APN：All-Photonics Network

Realizing high-capacity, low-latency, and low-power-consumption data communication
Optical connectivity between data centers and servers has already been completed. Going forward, the scope of optical application will be extended to the micro-level of the network. This initiative aims to achieve 100 times greater power efficiency, 125 times greater transmission capacity, and 1/200 of end-to-end latency.
-
Potential of remote data centers expanded through IOWN®
IOWN® will eliminate network latency between data centers located in remote areas and major cities such as Tokyo and Osaka, thereby enabling customers to build distributed and highly available server environments. In addition, by connecting small-scale data centers in regions like Hokkaido and Kyushu, where green power plants are concentrated, and promoting their utilization, it will promote the local generation and consumption of renewable energy.
