As we reported last week, Japan is expanding its push into quantum computing with a $335 million investment aimed at building domestic capacity. The Ministry of Economy, Trade, and Industry will fund more than 10 companies, including Fujitsu (FJTSY) and KDDI (KDDIY). The focus spans both hardware and software, with support for superconducting and optical quantum systems.

Now, the latest news suggests Fujitsu plans to build a superconducting quantum computer with over 10,000 physical qubits and 250 logical qubits by fiscal 2030. The project is part of Japan’s post-5G R&D program, which runs through 2027 under the New Energy and Industrial Technology Development Organization (NEDO). Fujitsu will lead this effort in partnership with research institutions, including RIKEN and AIST. Shares of Fujitsu are up 10% over the past five trading days.
Japan-Backed Quantum Plan Supports Fujitsu’s Growth Path
The upcoming machine will use Fujitsu’s STAR architecture, an early-stage fault-tolerant design first announced in 2024. According to the company, this approach is well-suited for materials science and energy modeling, two early use cases with strong computational needs. In 2025, Fujitsu launched a 256-qubit superconducting system, developed under the RIKEN collaboration that began in 2021. The company now plans to install a 1,000-qubit machine at its new facility in 2026, as a stepping stone toward the larger 10,000-qubit target.
In parallel, Fujitsu is working on diamond spin-based qubits in collaboration with Delft University of Technology and QuTech. The company expects to integrate these with superconducting chips by fiscal 2035 to build a 1,000 logical qubit system. Fujitsu is also developing its next-generation high-performance computing platform, powered by the FUJITSU-MONAKA processor line, which will support both classical and quantum workloads.
Japan’s broader quantum strategy calls for 10 million domestic users by 2030 and aims to create over $320 billion in new market value. Regional innovation hubs and a new research center, G-QuAT, will support talent development and commercial use. While quantum computing remains a long-term play, Fujitsu’s government-backed roadmap signals continued investment in high-tech infrastructure across Japan.
Fujitsu’s Technical Indicators
Fujitsu’s short-term technical indicators are mixed, with a Sell signal on momentum but a Strong Buy based on moving averages, supported by a share price above both the 20-day and 50-day trend lines.
