Mitsubishi Electric’s ME Innovation Fund Invests in JIJ for Quantum Mathematical Optimization Middleware

Mitsubishi Electric Corporation announced August 4, 2026, its ME Innovation Fund has invested in JIJ Inc., a Japanese startup developing middleware for mathematical optimization using quantum computers and related technologies. The company’s JijZept development platform is designed to help organizations solve diverse operational challenges through mathematical optimization without requiring specialized expertise. This is the fund’s fifteenth investment and supports Mitsubishi Electric’s broader strategy to advance research and development toward practical implementation of quantum technologies.

JijZept Middleware and Optimization Capabilities

JIJ develops middleware positioned between operating systems and applications to provide common functions supporting mathematical optimization. Mathematical optimization is a method for finding the minimum or maximum value of problems under given constraints using mathematical algorithms. The JijZept platform supplies modeling tools, solvers, and execution environments converting complex business problems into computable forms. The platform supports both classical and quantum optimization approaches.

Yu Yamashiro, CEO of JIJ Inc., stated the company uses mathematical optimization and quantum computing technologies to transform complex business challenges into computational forms. By combining JIJ’s strengths with Mitsubishi Electric’s expertise in quantum-related technologies, the parties look forward to advancing the application of quantum and optimization technologies in business.

Integration Path and Commercial Outlook

According to Mitsubishi Electric, quantum computing is transitioning from the research stage to practical application. The company has positioned quantum computing as a key priority of its overall R&D strategy. The ME Innovation Fund investment will enable Mitsubishi Electric to explore combining JIJ’s middleware-based development environment with its application development and software implementation knowhow, as well as its quantum technologies. This includes Mitsubishi Electric’s ongoing work in interconnection technology for quantum computers, a current focus area.

Komi Matsubara, Executive Officer (Vice President, Business Innovation) at Mitsubishi Electric Corporation, noted JIJ has many talented people with advanced expertise in using quantum technologies for optimization purposes and provides a development environment which enables varied 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, the company expects to accelerate the development of more robust solutions for customers.

Going forward, Mitsubishi Electric aims to establish technological superiority in quantum computing and accelerate R&D to achieve early commercial adoption. The ME Innovation Fund, established in 2022 and co-managed with Global Brain Corporation, invests in startups with collaboration potential across Mitsubishi Electric’s business domains and digital innovation areas.

Bottom Line

Mitsubishi Electric’s investment in JIJ supports exploration of middleware and quantum technology collaboration for industrial applications.
