Quantum Systems Establishes Japanese Subsidiary and Tokyo Office

The German defense company formed Quantum Systems Japan K.K. and plans to expand industrial cooperation with Mitsubishi Chemical and Panasonic under signed memorandums of understanding.

Quantum Systems announced on October 28, 2026 that it is establishing a permanent presence in Japan through a new subsidiary, Quantum Systems Japan K.K., and a local office in Tokyo. The company announced the move during Chancellor Friedrich Merz of Germany’s visit to Japan. It marks Quantum Systems’ next step in building an industrial presence in the country and its wider Pacific footprint.

The expansion follows the company’s opening of a Huntsville, Alabama outpost in August.

Quantum Systems Japan partnerships

Quantum Systems is building on existing relationships with Mitsubishi Chemical and Panasonic through signed memorandums of understanding intended to deepen industrial cooperation with and in Japan. The partnerships will combine Japanese manufacturing expertise with Quantum Systems’ experience in developing and producing unmanned systems. According to the company, the approach will bring it closer to Japanese customers, expand opportunities for industrial cooperation and contribute to more resilient domestic supply chains. The release does not detail the scope of either agreement.

Japan’s changing security environment is increasing demand for unmanned capabilities that operators can deploy, maintain and adapt to operational requirements. Building local industrial capacity is part of meeting that demand, as it reduces dependence on overseas supply chains and secures long-term access to defense technologies.

“Japan has understood where defence is heading: unmanned systems, rapid innovation and the industrial capacity to deliver at scale. Ukraine has shown why this matters. When personnel are scarce and threats evolve fast, technological advantage is decisive. Japan’s manufacturing strength and our operational experience are a powerful combination. We are proud to put down roots in Japan and honoured to help strengthen its defence industrial base,” said Sven Kruck, co-chief executive of Quantum Systems.

Multi-domain focus and MOSAIC UXS

Quantum Systems aims to support Japan’s growing requirements for integrated unmanned capabilities. To that end, it will draw on its experience across air, land and sea and on its MOSAIC UXS software platform, which coordinates unmanned systems across operational domains.

“Japan’s defence requirements are evolving, particularly as unmanned systems become an integral part of its future self defence force structure. The challenge is no longer simply acquiring individual platforms but ensuring that different capabilities can operate together across all domains. Our focus is on understanding where these operational gaps exist and working with Japanese partners to address them through integrated, mission-ready capabilities,” said Martin Karkour, chief revenue officer of Quantum Systems.

With its Japanese subsidiary and industrial partnerships, Quantum Systems will work directly with Japanese customers and industry. The company plans to focus on closer technological cooperation and on adapting its capabilities to Japan’s operational requirements. Quantum Systems employs more than 1,700 people across eight countries.
