NTT Data Begins Sales of 'NIKKEI KAI', Promoting Trusted Generative AI Utilization

Nikkei (Nikkei Inc., headquartered in Chiyoda-ku, Tokyo; President and CEO: Nobuhisa Iida, hereinafter 'Nikkei') and NTT Data Corporation (headquartered in Chiyoda-ku, Tokyo; President and CEO: Masanori Suzuki, hereinafter 'NTT Data') will begin sales collaboration on June 19, 2026, to promote the adoption of their enterprise-focused generative AI service, 'NIKKEI KAI'.

The two companies will combine Nikkei's highly reliable business information and data with NTT Data's customer-centric implementation capabilities to support enterprises in adopting generative AI with confidence. By enabling evidence-based information utilization in business processes such as research, planning, proposal development, and decision-making, the collaboration aims to enhance corporate productivity and elevate the quality of decision-making.

Generative AI is rapidly spreading as a technology that supports increased corporate productivity and new value creation. However, its business application faces challenges such as unclear sources of generated information and hallucination—instances where outputs contain factually incorrect content. These issues hinder its use in critical operations like strategic decision-making and business evaluation.

In response, there is growing demand for systems that generate responses based on reliable primary sources while clearly citing references. Nikkei possesses extensive business and industry data accumulated over many years, providing a trustworthy information foundation for corporate activities.

'NIKKEI KAI', the central offering of this partnership, leverages a comprehensive database including Nikkei's publications such as The Nikkei, industry-specific journals, and statistical data. The generative AI performs search and summarization functions to deliver responses with clearly cited sources. Enterprises can directly apply these responses to decision-making and business evaluation, as they can verify the underlying evidence.

NIKKEI KAI features the following key capabilities:

- Over 20 million articles and reports, with more than 2,000 new entries added daily

- Long-term trend analysis enabled by data dating back to the year 2000

- Industry information covering 53 media sources and approximately 550 industries

- 100,000 statistical series and startup data for around 20,000 companies

- Flexible delivery models including SaaS, API, and MCP

Through the sales of this service, NTT Data will provide its enterprise clients with opportunities to adopt trustworthy generative AI. Customers can utilize evidence-backed information throughout their internal workflows, including research, planning, proposal creation, and decision-making. Nikkei will deliver new forms of information utilization through generative AI, built upon its proprietary business data and insights. The collaboration enables enterprises to combine internally accumulated knowledge with high-reliability external information.

Through this sales partnership, both companies aim to establish generative AI as a foundational tool for corporate decision-making and business transformation. They plan to promote broader adoption across enterprises and expand access to the service. Furthermore, by integrating trusted information with generative AI, they aim to advance information utilization across entire corporate workflows. The companies will continue expanding their service offerings at the intersection of media, data, and technology.
