In addition to additional investments from existing investors, CVC funds related to Mitsubishi Electric, ANA Holdings, and Yamato Holdings joined as new participants. On the development side, JIJ will advance its AI agent service for mathematical optimization, “JijZept AI.” The service supports the cycle of requirements definition, mathematical modeling, and numerical experiments, and work is underway to add support for quantum programming. No official release date has been announced. In the quantum domain, JIJ will strengthen its software stack for gate‑model quantum computers, including the quantum programming language “Qamomile.” The company plans to develop middleware that combines quantum computers with HPC and classical optimization techniques, aiming for industrial deployment of quantum–classical hybrid computing. On the business side, JIJ will expand its development and deployment capabilities for mathematical optimization solutions, and use subsidiaries in the UK and Germany as footholds to pursue expansion across Europe and the United States. The company also plans to ramp up hiring for R&D, engineering, and business development roles. Key points • The total amount raised through the third‑party allocation is approximately ¥840 million, with Global Brain serving as the lead investor. • Funds will be allocated to expanding the mathematical optimization business, advancing “JijZept AI”, developing quantum‑oriented middleware, and overseas expansion. • JIJ will strengthen development of a quantum–classical hybrid platform that integrates gate‑model quantum computers, HPC, and classical optimization. • The company will expand its organizational structure for R&D and business development and pursue business growth centered on Europe and the United States.

JIJ has not disclosed its valuation or financial position, so it is not possible at this stage to fully assess the significance of this funding. Given the broad investment plan—which includes upgrading the AI‑driven optimization platform, quantum software development, overseas expansion, and hiring—how far approximately ¥840 million can support these initiatives is also an open question. Going forward, business progress, revenue growth, and the potential for additional fundraising will be important factors to monitor.

Do not give a high rating to summaries, paraphrases, explanations of technical terms, or generic observations such as "this will be worth watching" or "the timeline remains uncertain" if they could easily be produced by a general-purpose generative AI, even if they are well written. Use the following five-level rating scale. * **S — Advanced Original Expert Analysis**: Integrates multiple sources, comparisons, industry knowledge, or other information to provide important insights, evaluations, or a broader picture that would be difficult to obtain simply by reading the original sources individually * **A — Subject-Specific Expert Analysis**: Contains clear comparisons, reasoning, verification, or evaluation specific to the company, technology, or announcement being discussed * **B — Mainly Expert Explanation**: Provides specialist explanation or organization of the topic, but contains limited original analysis specific to the subject * **C — Organization and Summary of Primary Information**: Primarily summarizes primary information, but provides some added value through human editing, organization, or supplementary explanation * **D — AI-Level Summary and Formatting**: Offers little beyond the summarization and formatting of primary information that could be produced by a general-purpose generative AI, with almost no original analysis or informational value **Original reporting, proprietary data, original calculations, or the discovery of new facts are not required for an S rating.** An article may qualify for S if it compares and integrates multiple publicly available sources to provide important insights or a broader picture that readers could not easily obtain by reading those sources individually. However, do not give an S rating merely because the article contains a large amount of information, covers many subjects, or uses extensive technical terminology. In particular, consider the following points. * Does the article contain information or perspectives that would be difficult to obtain simply by reading the original announcement? * Does it contain comparisons, reasoning, verification, or evaluation specific to the subject? * Does it integrate multiple pieces of information to provide a new understanding or broader picture? * Could the content easily be produced by a general-purpose generative AI? * Are you avoiding giving a high rating merely because the article uses technical terminology or headings such as "Analysis" or "Key Points"? In your response, first briefly show the **S–D rating scale above**, and then clearly indicate **where this article falls within that scale**. Then briefly explain the following. * **Rating for this article: S / A / B / C / D** * **Reason for the rating** * **Specific passages that qualify as original analysis** If you are uncertain between two ratings, choose the lower one rather than the higher one.
