AT TOKYO to Launch “ATBeX Tokyo West Access Point” within
SECOM Trust Systems’ Secure Data Center
Enabling Seamless Private Connectivity to Mega Clouds from
Tokyo’s Western Area

AT TOKYO Corporation (Headquarters: Koto-ku, Tokyo, President and Chief Executive Officer: Tatsuya Izumida; hereinafter “AT TOKYO”) is pleased to announce the establishment of the “ATBeX¹ Tokyo West Access Point” (hereinafter “ATBeX Tokyo West AP”) within the Secure Data Center (SDC) operated by SECOM Trust Systems Co., Ltd. (Head Office: Shinjuku-ku, Tokyo; President and Representative Director: Tatsuyuki Nishimura). Service launch is scheduled for October 1, 2025.

AT TOKYO has been expanding its network platform service “ATBeX” nationwide, providing flexible connectivity to various service providers. ATBeX enables not only inter-data center connections but also seamless access to mega clouds², IXs³, ISPs, telecommunications carriers, and content providers. As part of its ongoing expansion to build a nationwide business platform, AT TOKYO will now open the new ATBeX Tokyo West AP.

With the growing adoption of hybrid environments combining on-premises and cloud infrastructure, and the rapid expansion of generative AI usage, demand for cloud connectivity continues to rise. The new access point will be located within the SDC campus, which includes the existing “New Secure Data Center” and “SDC Annex,” as well as the upcoming “SDC TC4” scheduled to open in October 2025.
SDC is highly regarded by customers requiring stringent security standards and high-quality, reliable infrastructure. Customers using SDC will be able to connect directly to ATBeX via in-house cabling.

Furthermore, by leveraging ATBeX’s nationwide business platform, customers in SDC can establish interconnections not only with AT TOKYO’s data centers but also with other data centers across Japan that are connected to ATBeX. This enables the construction of a wide-area, flexible network environment.
