With Artemis II home safely, we look at Japan's contributions to lunar exploration: Toyota's Lunar Cruiser, MHI's regenerative fuel cells, Bridgestone's lunar tires, and the rest of the hardware keeping crews alive on the Moon.
Casio and JAXA have demonstrated ±5cm positioning accuracy using LED-based visible light communication technology 'picalico' in a simulated lunar environment. With no GPS available on the Moon, this warehouse-born technology could become essential infrastructure for future lunar bases and rover operations.
Japanese space startup Synspective successfully launched its 8th StriX SAR satellite via Rocket Lab's Electron rocket from New Zealand. The company is building a 30-satellite constellation and holds a role in a 283.1 billion yen Japanese defense program, competing with Finland's ICEYE and America's Capella Space in the global SAR market.
Tohoku University spinoff Space Quarters has successfully demonstrated electron beam welding in simulated zero-gravity and lunar gravity environments aboard an aircraft. The company achieved a world-first by welding sintered lunar regolith — the sandy material covering the Moon's surface. With its ultra-compact 7 kg welding system and JAXA partnership, this breakthrough brings humanity one step closer to building infrastructure in space.
Japanese space laser startup Orbital Lasers has closed a $20 million Series A round backed by nine investors including Keio Innovation Initiative and JIC Venture Growth. Spun out from satellite operator SKY Perfect JSAT in 2024, the company develops compact, high-efficiency space lasers for debris removal via laser ablation and high-precision 3D terrain mapping via satellite LiDAR. We explore how it compares to Astroscale and SpaceX, and what it means for Japan's booming space startup ecosystem.
Japanese space startup Astroscale has announced its ISSA-J1 mission to realize a 'space safety patrol' service in orbit. As the space debris crisis intensifies with over 130 million pieces of junk circling Earth, this article explores how Astroscale's first-mover advantage in on-orbit servicing compares to rivals like ClearSpace and SpaceX, and what it means for Japan's growing space industry.
Chiba Institute of Technology has achieved the world's first ground combustion test of thrust vector control (TVC) using a gas hybrid rocket. Part of the Hestia Project, which aims to launch small satellites via balloon-based "Rockoon" method, this breakthrough demonstrated successful thrust vectoring at 2.0 kN over 8 seconds — opening a new path for affordable space access.
As AI demand pushes terrestrial data centers toward their limits in power and cooling, a new frontier is opening in orbit. Japan's NTT Group and SKY Perfect JSAT are moving first through their joint venture Space Compass, built on the IOWN optical platform, while Google's Project Suncatcher and the startup Starcloud race to put solar-powered AI infrastructure in space. Inside Japan's edge in inter-satellite optical links, and the radiation, cooling and launch-cost problems still unsolved.
Japan's Ministry of Defense has signed a landmark $1.8 billion contract for a satellite constellation project. A special purpose company "TriSat Constellation," formed by Mitsubishi Electric, SKY Perfect JSAT, and Mitsui, will lead the effort alongside domestic space startups like Synspective and iQPS. A deep dive into Japan's pivotal shift in space defense strategy.
Japanese space startup SpaceOne launched its third KAIROS small rocket on March 5, 2026 after repeated delays, but flight was aborted about 68.8 seconds after liftoff, a third straight failure following Flights 1 and 2. Learn what the company changed, what went wrong this time, and where its "space delivery service" dream stands now.
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 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.
A Japanese-led research team has detected the largest sulfur-bearing organic molecule ever found in interstellar space, a 13-atom ring compound near the Milky Way's center. The discovery bridges simple space chemistry and complex building blocks of life found in comets and meteorites, offering a key missing link in understanding life's cosmic origins.
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.
PASS (Portable Active Seismic Source), a compact seismic device developed by the University of Tokyo, has been selected for NASA's Artemis IV mission. Astronauts will use this staff-like tool to generate vibrations and map the Moon's subsurface structure. Learn how this Japanese innovation will support water resource exploration, mineral surveys, and foundation assessments for future lunar bases.
