“JISDA, formally known as Japan Integrated Security Design Agency and headquartered in Tokyo’s Chiyoda Ward, announced the availability of the ACM-01 ‘Shiraha’ on April 14, 2026, positioning it as a purpose-built training platform intended to be used, damaged, and replaced rather than preserved.”
“The Shiraha is a fixed-wing unmanned aerial vehicle with a wingspan of 1.9 meters and a wooden airframe. Every component, from structural materials through subsystems, is sourced and manufactured within Japan. JISDA describes the pricing not as a market promotion but as the result of deliberately stripping the design down to the minimum specifications required for training use, cutting costs at every stage without targeting performance benchmarks that only matter in operational deployments. For short-range operational roles beyond training, the company has indicated the design is expandable — extended range, enhanced communications, and additional capabilities can be added, though each addition carries a corresponding cost increase above the base 70,000 yen figure.”
“The Shiraha’s development is directly informed by field research JISDA’s founding team conducted in Ukraine over approximately three years before the company’s formal establishment in November 2025. That research extended beyond Kyiv and rear-area logistics nodes to areas near active front lines, including locations approximately 20 kilometers from the line of contact…”
