News Releases

MC Digital Realty, Inc. (hereinafter “MCDR”) and OPTAGE Inc. (hereinafter “OPTAGE”) have agreed to collaborate on enhancing connectivity between data centers in the Saito area and central Osaka.
By combining MCDR's KIX Campus in Saito, Osaka, with OPTAGE's DCI (Data Center Interconnection) service “Flex Dark Fiber,” the two companies will provide customers at KIX Campus with additional connectivity options to major data centers in central Osaka.
This collaboration will enable customers to build flexible network configurations tailored to their needs while ensuring redundancy through diverse fiber routes.

1. Background and Objectives

The rapid growth of generative AI and cloud services has led to increasing demand for data centers worldwide. As a result, DCI services are becoming increasingly important, with growing demand for high-quality, low-latency, and resilient network connectivity.
In Japan, critical digital infrastructure, including data centers, is concentrated in the Tokyo metropolitan area. From the perspective of enhancing the resilience of digital infrastructure, one of the key challenges is to promote the geographic decentralization of these facilities and strengthen telecommunications networks. Against this backdrop, the development of integrated data center and network infrastructure to support growing AI demand is becoming increasingly important in the Kansai region.
OPTAGE provides high-quality connectivity to major data centers in central Osaka and other areas through its extensive optical fiber network throughout Kansai. MCDR operates KIX Campus, a large-scale data center campus located in Saito (Ibaraki and Minoh, Osaka).
By combining OPTAGE's high-quality network connectivity with MCDR's high-density data center infrastructure, the two companies aim to meet the diverse and evolving needs of customers in the AI era.
Through solutions that leverage the strengths of both companies, MCDR and OPTAGE will contribute to further strengthening digital infrastructure in the Kansai region.

2. Strengths of Each Company

MC Digital Realty

MCDR operates KIX Campus in the Saito area of Osaka, with a total IT power capacity of 74 MW. The campus currently consists of four data centers, all designed to support high-power, high-density IT environments while offering scalability to meet future demand.
KIX13 has obtained DGX-Ready Data Center certification, providing an infrastructure environment capable of supporting AI workloads.
MCDR also plans to open KIX15, a new data center with 24 MW of IT power capacity, in the fourth quarter of 2028.
Lastly, MCDR is promoting the “Kansai AI Infrastructure Co-Creation Project,” centered around the KIX Campus, and working to strengthen connectivity with data centers and major network hubs in the Osaka metropolitan area through collaboration with telecommunications carriers and technology partners.

OPTAGE

OPTAGE provides the DCI service “Flex Dark Fiber,” built on its optical fiber network spanning the Kansai region. OPTAGE will significantly enhance the optical fiber network connecting the Saito area with central Osaka in response to the growing demand for connectivity between data centers.
Route-diverse redundancy will be provided between the KIX Campus (KIX10, KIX11, KIX12, KIX13, and KIX15) and central Osaka by leveraging this optical fiber network.
One of these routes will be a high-quality, short-distance route utilizing an underground path. Similarly, a redundant configuration using diverse routes can be provided between OPTAGE’s Sonezaki Data Center, “OC1,” and the KIX Campus.
In addition, OPTAGE's domestic DCI service “AOC (All-Optical Connect),” which connects OC1 and major data centers in the Tokyo metropolitan area via an all-optical network, will enable the company to meet wide-area network connectivity needs between Tokyo and Osaka, as well as within the Kansai region.
