Tokyo, December 7, 2023 – Hitachi, Ltd. (TSE: 6501, "Hitachi") is actively leveraging rapidly evolving generative AI as a growth engine for the entire Group and is promoting an initiative called "AI Transformation" both internally and externally that will significantly improve business productivity and create new business opportunities. To further strengthen our efforts, the position of "Chief AI Transformation Officer" was created on December 1 to promote transformation using AI in each business area. Kimihiro Kaimori, Katsuhiro Samizo, and Jun Yoshida have been appointed as Chief AI Transformation Officers for the Green Energy & Mobility Sector, the Connective Industries Sector, and the Digital Systems & Services Sector, respectively.

As professionals with high-level business expertise in their respective business areas, the three are responsible for the company-wide AI transformation strategy within each sector, enhancing the effectiveness of the project by leveraging their respective business expertise, and leading the way in achieving results, such as productivity improvement.


Generative AI is one of the key next-technology technologies that will strongly support the creation of innovation. Hitachi is actively promoting the use of generative AI with a focus on creating value for customers and society, as well as transforming internal business processes throughout the entire Group. In May 2023, we established "Generative AI Center" which is formulating guidelines and creating use cases for safe and effective use. The center also promotes co-creation with customers in various industries by providing consulting, environment creation and operational support services tailored to customer needs.

Within the Hitachi Group, a company-wide project to reform internal processes using generative AI is being led by Toshiaki Tokunaga, Representative Executive Officer and Executive Vice President, General Manager of Digital Systems & Services Division. The project focuses on increasing productivity and refining system development and customer service. For example, we are promoting research and verification to improve productivity in software development, such as code generation, testing efficiency, and safety considerations when applying generative AI. In addition, Hitachi is focusing on advancing customer service to reduce the time required to investigate similar cases by integrating past inquiries and operational manuals with generative AI resulting in quick maintenance operations.

Hitachi will continue with generative AI trials throughout the entire Group, which has approximately 320,000 employees worldwide. Hitachi will apply its experience and technologies to co-creation activities with customers to accelerate AI transformation, in order to solve various issues and create innovations for the realization of a sustainable society.

Mission of the Chief AI Transformation Officer

The newly created "Chief AI Transformation Officer" will be responsible for coordinating and embedding the company-wide AI transformation strategy in each sector and will lead the implementation of the transformation in each sector based on their business expertise.

They will also serve as a hub between the sectors, facilitating the seamless sharing of validation results, technologies, and know-how, accumulating best practices, and promoting the creation of synergies with diverse knowledge to accelerate company-wide projects aimed at transforming internal processes through generative AI. This will accelerate the company-wide project that aims to transform internal processes through generative AI. In order to generate innovation using generative AI, they will also work to reform the organizational culture by fostering creative thinking and skills among employees, changing their mindsets, and instilling an understanding of AI transformation.
