Japan bets on cardboard drones to revolutionize its defense and become one of the global leaders in the field

Cardboard weapons. Like many countries since the beginning of the large-scale invasion of Ukraine by Russia, Japan is turning towards a revolution in its defense by putting drones and unmanned systems at the heart of its new strategy. The small difference is that Tokyo has decided to turn to Air Kamui, a bold company specializing in the production of military drones… made of cardboard.

This choice to turn to Air Kamui is part of Tokyo’s proactive policy to support innovative startups, seeking to inject new technological approaches more quickly into the development of its defense capabilities.

Defense Minister Shinjiro Koizumi has clearly stated that “strengthening ties with defense-focused startups is essential” in order to achieve the set goals. The country aims to become “the Self-Defense Force that makes the most use of drones and other unmanned assets in the world.” An objective that marks a significant turning point for this traditionally cautious nation in terms of autonomous systems, notes the specialized site Defence Blog.

Designed to be shot down during training

Lightness, biodegradability, reduced cost, large-scale manufacturing speed… far from being a mere gadget to stand out from other drones, cardboard presents many advantages, especially for target drones designed to be shot down during training. Instead of investing in costly composite cells for drones destined for destruction, cardboard offers an economical and effective alternative, allowing more frequent training without the constraints of recovery and refurbishment.

Beyond the acquisition of drones, Japan aims to be a global leader in the operational integration of unmanned systems in its various military branches. In addition to mass production, this includes developing doctrines, training teams, establishing logistics and maintenance, and gaining operational experience through intensive use of unmanned systems in real conditions.

This evolution is part of a broader context of strengthening Japan’s defense. Tokyo has committed to doubling its military spending relative to GDP. Unmanned systems are a priority investment, drawing lessons from recent conflicts that have demonstrated the transformative role of drones.
