Messages from Keidanren Executives and Contributed articles to Keidanren Journals March, 2026 Taking on the Challenge of Quantum Computing

Takahito TOKITA Vice Chair, Keidanren
Representative Director, CEO, FUJITSU LIMITED

A century has passed since the birth of quantum mechanics. Now, we are currently at the dawn of a new quantum revolution. In 2025, the Japanese government positioned quantum as one of the key investment areas in its growth strategy. Quantum computers will open up computational domains that cannot be solved with conventional computing, and hold the potential to transform the world of computing.

For example, solving climate change issues will require extremely detailed simulations. The key to achieving this lies in a completely new calculation method that utilizes quantum superposition and quantum entanglement, and quantum computers leveraging them. It is expected to be a breakthrough that will surpass the limits of conventional computing power. This calculation method is also being considered for applications in a wide range of other fields, including ultra precise simulations for complex chemical reactions in the development of new materials and drugs, portfolio analysis and risk management in the financial sector, as well as supply chain and traffic control optimization in the manufacturing industry.

Although Japan possesses world-class cutting-edge technologies, up until now, it has struggled with societal implementation. I would like to leverage this experience to advance the implementation of quantum computers through a more strategic approach. The world-renowned Japanese manufacturing industry and healthcare sector possess vast amounts of data, a deep expertise cultivated in their established industries, and an awareness of issues faced on the frontlines. By combining the advanced analytical capabilities of quantum computers with these, we will be able to establish an advantage that is unique to Japan as a global leader. To achieve this, we must hone our skills by working with leading global research institutions, and have an unwavering determination to become the world's best in technology. In addition, Japanese companies and startups from a wide range of industrial fields must engage in discussions from the research stage and advance strategic and long-term initiatives aimed toward precise societal implementation.

Humanity has always advanced technology and overcome the barriers that stood in the way of its progress. Quantum computing initiatives will generate new industries and serve as a breakthrough to solve societal issues. Japan should make a unified effort to take on this challenge and pave the way toward a bright future.
