— For furthering the development of digital platform business in the Inzai area by utilizing fiber-optic lines,
which offer high quality, speed, and security, owned by ARTERIA Networks —

ARTERIA Networks Corporation (Head Office: Minato-ku, Tokyo; President and CEO: Koji Kabumoto; hereinafter ARTERIA Networks) decided to install a dedicated line with a bandwidth of up to 100 Gbps to connect to the Tokyo 2 Data Center (hereinafter: NRT 10) of MC Digital Realty, Inc. (Head Office: Minato-ku, Tokyo; Representative Director and CEO: Bampo Tezuka; hereinafter MCDR) which is scheduled to be completed in the Inzai area in September 2021.


The Inzai area attracts attention from major foreign IT companies, major system integrators, and data center operators, with its vast land, abundant power supply, high ground stability, and convenient access from Tokyo and Narita airport. It is one of the main areas where large-scale data centers are concentrated.

ARTERIA Networks conducts strategic expansion of its optical networks in the Inzai Area. The company has a competitive advantage in the access to landing stations that connect to international submarine cables in areas such as the northern area of Ibaraki Prefecture and Minamiboso area of Chiba Prefecture, as well as a major data center area in Tokyo which is a nexus for both domestic and foreign connections, actively promoting collaboration and cooperation with data center operators.

In order to meet the needs of foreign major cloud operators and system integrators, as communication traffic increases and promotion of digital transformation accelerates with the spread of COVID-19, ARTERIA Networks has decided to install a dedicated line to the cutting-edge NRT 10 data center of MCDR, with the intent to contribute to the world-wide business development in Inzai Area.

This allows DynaEther, a low-latency, high-quality dedicated line service of up to 100 Gbps, to be available within a short delivery time for customers demanding access to major data centers in Tokyo and landing stations that connect to international submarine cables from the NRT 10 data center.

ARTERIA Networks will continue to actively strengthen and expand fiber optic networks to meet the demand for high-quality networks which are vital in operating large-scale data centers in the Inzai area, and contribute to the further development of digital platform business in the Inzai area.

Mr. Bampo Tezuka, Representative Director and CEO of MC Digital Realty, expressed his vision as follows.

"In addition to using large-scale data centers, customers in our NRT Connected Campus want an environment that allows them to transact large amounts of global traffic. By collaborating with Arteria Networks, we will provide data center services that can meet a wide range of customer needs including such significant traffic demand. "

Robert Davidson, Senior Director of Network Strategy in Digital Realty Asia Pacific, said,

“Beyond Japan, Digital Realty operates key centers of data exchange on PlatformDIGITAL® in major cities across Asia Pacific such as Singapore, Hong Kong, Sydney, and Melbourne. Once this new interconnection path to the nearby submarine cable landing station is deployed, customers who use our data centers cross-regionally will have high-speed, low-latency access to Digital Realty’s global connected data community. As an alternative to the Tokyo Metro area, where network hubs have been traditionally concentrated, we will provide new distributed network hub functions connecting Japan to the rest of the world.”

Yasutoshi Kikuchi, Executive Officer and CTO at ARTERIA Networks, commented about this collaboration:

“Our company has worked on creating our own fiber optic networks to flexibly meet the needs of the customers in a timely manner. By installing our equipment to connect to MCDR’s NRT 10, we can synergize the two companies and exponentially increase the value of the Inzai area. We aim to contribute to the growth of our customers’ business by providing access to major data centers in Tokyo and submarine cables that connect to other countries from NRT 10.”

●High quality and reliable full bandwidth guarantee

Because fixed bandwidth is allocated per line, bandwidth is fully guaranteed and robust security is provided.



There are no restrictions on Layer 3 or higher protocols, so it can be used widely.


●Secure link-down forwarding
