Japan's Space Data Inc. and CYPHIC, the country's only electronic warfare startup, have launched a strategic partnership combining digital twin technology with anti-GPS spoofing capabilities. A deep look at how Japanese defense tech startups are tackling modern electronic warfare threats.
Japanese fusion startup Helical Fusion and veteran manufacturer Sugino Machine have jointly developed the world's only dedicated machine for producing high-temperature superconducting coils. Standing 6 meters tall and weighing 12 tons, this device is essential for building the "Helix HARUKA" demonstration reactor, bringing Japan closer to achieving the world's first commercial fusion power in the 2030s.
Japanese startup Milk. is developing technology that combines satellite-derived "hyperspectral cameras" with color AI to detect cancer—including which organ is affected—from a simple urine test. With 98% accuracy even for pancreatic cancer, this innovation could revolutionize how we screen for humanity's deadliest enemy.
Japanese startup AirX has signed a binding order with Brazil's Eve Air Mobility for two eVTOL "flying car" aircraft, with options to expand to 50 units in a deal potentially worth $150 million. Targeting 2029 for sightseeing and last-mile transport services in Tokyo and Osaka, this agreement marks a major milestone in Japan's push toward urban air mobility — following successful demo flights at Expo 2025 Osaka.
Japanese startup AstroX has raised $15 million in Series A funding to develop its revolutionary Rockoon launch system — using high-altitude balloons to carry rockets to the stratosphere before firing them into space. Based in Fukushima's Minamisoma, the company aims to reach space by 2026 and achieve orbital insertion by 2029, challenging the global space launch industry with a low-cost, flexible alternative.
Japanese space startup ALE announces "Starlight Challenge," its third attempt to create the world's first artificial shooting stars after two previous setbacks. Targeting a 2028 space demonstration and commercialization by 2029, this ambitious project blends space entertainment with atmospheric science research.
University of Tokyo-born startup Pale Blue enters the Orbital Transfer Vehicle (OTV) business after being selected for JAXA's Space Strategy Fund. With its unique water-based propulsion technology, the company aims to create "branch line transportation" in space. A deep dive into Japan's growing space industry.
Singapore startup Flint begins mass production of biodegradable paper batteries. Made from cellulose, decomposing in 6 weeks, with no lithium or cobalt. Pilot programs with Logitech and Amazon underway, AA/AAA formats expected in 2026. Could this be the solution to battery waste?
UTokyo Matsuo Lab spinoff Akari raises ¥5 billion ($33M) from Mitsubishi Electric, reaching ¥100 billion+ valuation. Learn how this 5-year-old AI startup achieved profitability from day one, partnered with 1,000+ companies, and is building the "next-generation industrial OS" for Japan's manufacturing sector.
Japanese startup AirKamuy has developed a cardboard military drone priced at just $2,000—one-tenth the cost of conventional fixed-wing UAVs. The AirKamuy 150 assembles in 5 minutes, flies at 120 km/h for 2 hours, and is attracting attention from Japan's Ministry of Defense and Coast Guard. How is this disruptive innovation reshaping defense technology?
