An acquisition of e-shelter by Nippon Telegraph & Telephone Communications is the latest in the NTT Corp's overseas expansion due to a dwindling home market.
NTT bought South African IT firm Dimension Data for 382 billion yen ($3.2 billion) in 2010, followed by takeover deals with a combined worth of 85.5 billion yen ($715.42 million) of two US cloud computing firms, Virtela Technology Services Inc and Raging Wire Data centres in 2013.
The talks were first reported by the Nikkei business daily.
E-shelter is a data centre developer and provider founded in 2000. It has data centres in Hamburg, Berlin, Frankfurt, Zurich, Vienna, and Munich.
