Quantum Systems Establishes Permanent Japanese Subsidiary

Quantum Systems entered Japan's defence market on October 28, 2026. The company announced a permanent local presence through a new subsidiary, Quantum Systems Japan K.K., and a Tokyo office during German Chancellor Friedrich Merz's visit to the country. The subsidiary will provide a permanent local presence for working with customers and adapting systems to Japanese operational requirements.

Quantum Systems aims to support Japan’s growing requirements for integrated unmanned capabilities. The new office will focus on cooperation with Japanese customers and adapting unmanned systems to the needs of the Japan Self-Defense Forces. This move marks another stage in the company's international expansion, following the opening of an unmanned systems development center in Huntsville, Alabama, in August.

Partnerships and industrial cooperation

Quantum Systems is building on existing relationships with Mitsubishi Chemical and Panasonic through signed memorandums of understanding. The partnerships will combine Japanese manufacturing expertise with Quantum Systems’ experience in developing and producing unmanned systems.

The cooperation aims to strengthen the local industrial base and reduce dependence on foreign supply chains. The memoranda extend existing relationships and are intended to reduce reliance on overseas supply chains and support long-term access to defence technologies. Sven Kruck, co-CEO of Quantum Systems, stated that Japan recognized the evolving defense industry direction including unmanned systems, rapid innovation, and large-scale production capacity.

MOSAIC UXS and integrated capabilities

Quantum Systems will offer integrated air, land, and maritime solutions based on its MOSAIC UXS software platform. The company will draw on its experience across air, land and sea and on this platform, which coordinates unmanned systems across operational domains.

MOSAIC UXS enables different unmanned systems to operate in coordination. Martin Karkour, Quantum Systems' chief revenue officer, said the challenge is no longer simply acquiring individual platforms but ensuring that different capabilities can operate together across all domains. The company focuses on understanding operational gaps and working with Japanese partners to address them through integrated, mission-ready capabilities.

Leadership perspective on demand and innovation

Japan’s changing security environment is increasing demand for unmanned capabilities that operators can deploy, maintain and adapt. 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.

Sven Kruck added that Ukraine demonstrated why this mattered. He noted that technological superiority became decisive when personnel were in short supply and threats evolved rapidly. Quantum Systems is honoured to help strengthen Japan's defence industrial base.

Portfolio and operational scope

The company's portfolio includes unmanned systems, sensors and counter-unmanned technologies for defence, security and civil resilience customers. Quantum Systems employs more than 1,700 people across eight countries. The company is also expanding operations in Ukraine, with Germany funding the production of tens of thousands of the company's interceptor drones to defend against Russian strike UAVs.

Quantum Systems will work with Japanese customers and the Japan Self-Defense Forces to adapt unmanned systems to operational requirements.
