Overview
NTT DATA Group Corporation is the IT services arm of the Japanese telecommunications group NTT. Its corporate profile gives consolidated net sales of ¥4,638.7 billion for the fiscal year ended 31 March 2025 and a consolidated workforce of 197,800 people[3]. The company’s disclosure archive includes a notice dated 25 September 2025 announcing the delisting of its shares[4], after which NTT DATA became a wholly owned subsidiary of its parent. Because it is no longer listed, this ranking uses the most recent full-year figure on the company’s own profile page. That figure is one fiscal year older than the data used for most other entries. NTT DATA provides consulting, systems integration, application management, infrastructure and data-centre services across Japan, the Americas, Europe and Asia-Pacific.
