RIKEN unveiled two supercomputers on the same day: RIKYU for AI for Science and ROQUO for quantum-HPC. Both are Japan's first to run GB200 NVL4 and Quantum-X800 InfiniBand. We compare them with US efforts like xAI's Colossus and the DOE Genesis Mission, and China, to read Japan's bet on purpose over scale.
HOKUSHIN-1, a cubesat from three Japanese universities, was deployed from the ISS on June 19. Why it proves deep-space tech in low orbit first, where failure is cheap.
Muon-catalyzed fusion needs no plasma and no 100-million-degree heat, and it is not 1989's discredited cold fusion. A Japan-led team made the first direct observation of muonic-molecule resonance states, closing a long-standing theory-experiment gap.
Sinfonia Technology, better known for semiconductor robots, has paired a cold crucible melting furnace with a disk atomizer to make highly spherical powder from high-melting metals like titanium and molybdenum. A look at the unglamorous powder that feeds metal 3D printing, and Japan's stake in it.
A Kyushu University team showed for the first time that RPS19, long known as an anemia gene, also suppresses cancer by keeping p53 working. The finding hints at repurposing existing MDM2-inhibitor drugs.
Toray's new TSW-K/M/V RO membranes remove over 99.9% of salt and enough boron to run seawater desalination in a single pass, trimming energy, equipment and cost. Here's why it matters worldwide.
Kubota says its existing waste-melting furnaces destroyed three regulated PFAS at over 99.999 percent, with greenhouse-gas markers below detection. We check whether 'destroying forever chemicals' is really the breakthrough it sounds like.
Since 2016, a Japan-led ALMA team kept breaking distance records for oxygen in the early universe. In 2026 they finally caught the cold neutral gas itself: [O I] 145μm in four galaxies ~13 billion years back. The decade-long quest, and how it complements the Webb-led race.
New image analysis confirms Japan's 228-gram transformable robot SORA-Q (LEV-2) moved about 0.13m and turned 180 degrees on the Moon entirely on its own, earning a Science Robotics cover. Built with help from a toy maker, the palm-sized machine opens a new path for small-scale exploration aimed at caves, steep slopes and, eventually, Mars.
Mitsubishi Electric is building an orbital transfer vehicle under Japan's Space Strategy Fund. We map the race: America's speed-and-price game led by Impulse Space, China's dual-use Shijian maneuvers, and Japan's unconventional bet on the docking skills it honed resupplying the ISS.
A Tohoku University team grew rice to the heading stage in soil mimicking the Moon's surface, using fertilizer made from nothing but air and electricity via plasma. The unlikely inspiration? Gundam's beam saber. As NASA pushes toward a lunar base, it could become foundational tech for growing food in space.
