Commentary:
Yu Yamashiro, Founder and CEO of JIJ:
“Since JIJ was founded, we have worked at the intersection of quantum computing and mathematical optimization to address complex challenges across industries. Technologies developed through our research are now being deployed in day-to-day enterprise operations, and we believe this financing reflects confidence in both our technology and our ability to bring it into practice.
JIJ began with my desire to ‘see the future through computation.’ I believe that making complex challenges computable creates better choices and helps society move forward.
With this financing, we will advance our AI-enabled optimization platform and prepare for integration with gate-based quantum computers. By drawing on both mathematical optimization and hybrid quantum-classical computing, we aim to make a greater contribution to solving complex industrial challenges. By combining cutting-edge research with implementation expertise and bridging academia and industry, we will continue to advance our mission: “Making society computable to unlock humanity’s potential.”
Yasuhiko Yurimoto, President & CEO, Global Brain Corporation:
“We are deeply honored to lead this round once again, following our previous investment. Since our initial investment in 2023, JIJ has established a strong track record of adoption across a wide range of industries, addressing real-world business challenges. JIJ’s technology has also earned high acclaim globally, and we are truly excited to see them leverage this capital to accelerate their expansion both domestically and internationally. Global Brain remains fully committed to supporting JIJ as they rapidly grow as a leading player in the quantum optimization field.”
Shunpei Tatebayashi, General Manager, KDDI Corporation
“As international competition in quantum technologies continues to intensify, accelerating commercialization and industrial adoption has become a key policy priority in Japan.
Against this backdrop, JIJ Inc. has steadily expanded its business in the field of mathematical optimization since our initial investment. In 2025, KDDI further strengthened its collaboration with JIJ by entering into a strategic partnership focused on the development and commercialization of quantum computing technologies. Quantum technologies are expected to create value across a wide range of industries in the years ahead. By combining JIJ’s quantum optimization technology with KDDI’s AI and quantum computing platform, we aim to accelerate the industrial application of quantum computing and unlock new value across diverse industries.”
Komi Matsubara, Executive Officer (Vice President, Business Innovation), Mitsubishi Electric Corporation
“JIJ has many talented people with advanced expertise in using quantum technologies for optimization purposes. It is also providing a development environment that enables diverse users to solve complex, real-world business challenges through mathematical optimization. By combining Mitsubishi Electric’s quantum computing technologies with JIJ’s quantum and mathematical optimization platform, we expect to accelerate the development of even more robust solutions for customers.”
Yoshiaki Tsuda, Executive Vice President, Director of Future Creation, ANA HOLDINGS INC.
“ANA operates approximately 1,000 flights a day, dealing with vast amounts of data across various scenarios in our pursuit of optimal operations. When I was previously in charge of flight scheduling, the optimization model we used took an entire night just to process a single scenario, which made daily operations quite challenging.
We decided to make this investment with high expectations that JIJ’s quantum technology-enabled mathematical optimization platform will be widely implemented in society as solutions for such complex planning tasks. While our collaboration has already begun—including the selection of our joint proposal under the Space Strategic Fund—we aim to mutually enhance the corporate value of both companies through the optimization of airline operations.”
Kenji Mori, Manager, Innovation Promotion, Yamato Holdings Co., Ltd.
“We made this investment in recognition of JIJ Inc.’s exceptional technological capabilities as a leader in Japan’s quantum annealing research, as well as their end-to-end support—from strategy to implementation—for complex challenges. We expect their technology to play a major role in optimizing the Yamato Group’s business resources. Going forward, we plan to support their growth by sharing our logistics expertise. At the same time, we look forward to exploring various collaborative opportunities—ranging from enhancing frontline operations to optimizing the entire supply chain—as we jointly unlock the potential of quantum technology in logistics.”
Hideaki Yajima, President & CEO, Fujitsu Ventures Limited:
“JIJ combines deep expertise in mathematical optimization and quantum technology with the ability to take advanced computing technologies from foundational research and middleware development through to deployment in industrial settings. This breadth of capability sets JIJ apart, even among companies operating globally in the field.
JIJ also holds a distinctive position at the intersection of academia, industry, and technology ecosystems around the world. We believe the company will play an increasingly important role in turning advanced technologies into practical value for industry.
Mathematical optimization and quantum technology are also closely aligned with the Fujitsu Group’s strategic areas of focus. Since our initial investment, collaboration between JIJ and the Fujitsu Group has continued to expand. Through this follow-on investment, we look forward to deepening that relationship and working together to create new value.”
