ST Telemedia Global Data Centres (STT GDC), a carrier-neutral data center operator headquartered in Singapore, today announced its expansion plan for two new data centers in Tokyo, Japan, which will be developed by and pre-leased from Goodman Group, an Australian owner, developer, and manager of industrial property.

Notably, STT GDC’s partnership with Goodman Group marks the company’s entry into the Japan data center market.

Tokyo, Japan Data Centers – STT GDC

STT GDC’s two new data centers in Tokyo, Japan comprise a development potential of 60 megawatts of IT power across two buildings, spanning 646k sqft (60k sqm) of gross floor area. Specifically, STT GDC’s Tokyo, Japan data center campus will be located within Goodman Business Park in Inzai City, Chiba Prefecture, within the Greater Tokyo area.

Development Plan

Goodman Japan will develop the shell and core of the Tokyo data centers and pre-lease the buildings on a long-term basis to STT GDC. Subsequently, STT GDC will fit-out and then operate the data centers, with the first building expected to be ready for service in Q2 2024.


STT GDC will target the significant capacity demands of hyperscale companies and enterprises seeking large-scale facilities. For example, in May 2019, Google purchased land at Goodman Business Park in order “to meet the growing needs of Google Japan’s customers, such as Cloud”.

Additionally, STT GDC’s hyperscale data centers will support the expansion of 5G communication services in Japan. Indeed, by 2029, Japan is estimated to reach 151 million 5G subscriptions in the country.
