DX & AX

Through digital transformation (DX) and AI transformation (AX#1) initiatives such as promoting data utilization and generative AI adoption, streamlining business processes, and the democratization of DX, we will improve employee productivity and effect the transformation from information aggregation to advanced information utilization, contributing to further business expansion of the Hitachi Group.

Utilization of AI

We are leading the way in rapidly developing generative AI technologies and promoting the creation of an environment in which our employees can utilize them.

We have deployed an AI assistant within the Hitachi Group. This allows users to use generative AI safely, securely, and at low cost.

By providing functionality that enables users to reference knowledge accumulated throughout the Hitachi Group, we can form a collective set of knowledge and contribute to the creation of better business results.

Utilizing AI to improve internal business efficiency


As AI technology continues to evolve and its adoption in business enters a full-scale phase, the Hitachi Group is developing a common platform that enables employees worldwide to use AI safely and securely. The AI assistant exclusively for Group employees has become established as an AI tool that supports daily operations and promotes AI utilization across regional boundaries, with the aim of improving productivity and operational quality globally. Beyond general-purpose operational support, we are also advancing AI utilization tailored to specific industries and operational characteristics. For example, in service desk operations, AI automatically responds to inquiries based on product specifications, manuals, and FAQs, among other tasks.

Amid advances in AI, AI agents, which autonomously make decisions, take action, and support business operations, have become a key focus for achieving business transformation. The Hitachi Group is also capitalizing on this trend. We are advancing the use of AI agents that integrate business systems and knowledge across the organization, improving the efficiency and sophistication of individual operations, and promoting autonomous operational support that goes beyond simple conversational AI. In addition, AI agents seamlessly support everything from information collection and analysis through decision-making support and business process automation, contributing to higher productivity across operations. Furthermore, we are developing the platform that supports the use of these AI agents and gradually expanding their application to business operations.

Going forward, the Hitachi Group will continue to promote and advance the global use of AI and accelerate value creation as One Hitachi by leveraging AI agents that transform business processes. Through these initiatives, we aim to apply the AI utilization expertise developed within the Hitachi Group to customer-facing products and services over the long term.
