The result: vivid prints that never fade, with applications from eco-friendly packaging to anti-counterfeit security.
Maya Kawana, eldest daughter of SoftBank's Masayoshi Son, has become CEO of biotech startup Spiber after a private restructuring left roughly ¥36 billion in debt with the old entity. From Goldman Sachs to spider silk, we explore her rebuilding plan, the biomaterials race, and what this means for Japan's deep-tech ecosystem.
Sekisui Chemical has officially launched SOLAFIL, Japan's first commercially produced film-type perovskite solar cell. Lightweight and flexible enough for walls and curved surfaces, this next-gen technology positions Japan at the forefront of the global perovskite race against Chinese and European rivals.
Researchers at Osaka and Yamagata Universities have created a 'smart plastic' whose degradation can be toggled on and off with light. Using movable molecular rings, the material balances durability with biodegradability — and can even encode QR codes revealed by enzyme digestion. Published in ACS Nano.
Bio-venture Spiber's financial crisis delivers a fatal blow to Japan's Cool Japan Fund, pushing cumulative losses beyond $2.5 billion. With its third missed target triggering dissolution discussions, we analyze Japan's structural challenges in government-backed startup investment compared to Singapore's Temasek and other sovereign wealth funds.
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.
Japan's GX Promotion Organization will guarantee up to $1.2 billion in debt for JFE Holdings' next-generation electric arc furnace. This $2.2 billion project aims to cut 2.6 million tonnes of CO₂ annually by replacing a blast furnace. How does Japan's industrial decarbonization strategy compare to the EU's CBAM and America's IRA?
Power Diamond Systems demonstrated the world's first actual power conversion using a diamond MOSFET in a DC-DC converter circuit. Following their recent 200V/1A switching milestone, this breakthrough advances diamond semiconductors from device-level testing to real circuit operation.
Fusion power, maglev trains, and hydrogen aircraft are driving a resurgence in Japan's high-temperature superconductor (HTS) technology. Fujikura is investing $750M+ to boost wire production up to 8x, Toshiba partners with Airbus on superconducting motors, and Toyota integrates HTS into hydrogen cars. As competition with U.S. giant CFS intensifies, Japan's deep HTS supply chain emerges as a critical global asset.
Seiko Epson and Taiwan's Manz Asia have formed a strategic partnership to develop inkjet-based semiconductor manufacturing. Their 'additive' approach prints functional materials directly onto substrates without photomasks, cutting costs and environmental impact versus traditional photolithography. We explore their Lab-to-Fab equipment roadmap and Japan's edge in printed electronics.
Japan's Power Diamond Systems, a Waseda University spinoff, achieved the world's first 200V/1A switching operation with a diamond MOSFET. With 550V breakdown voltage and 0.8A drain current in a single device, diamond semiconductors could surpass SiC and GaN as the ultimate power semiconductor for EVs and renewable energy.
Spider silk — five times stronger than steel by weight — is finally becoming a mass-produced reality. U.S.-based Kraig Biocraft targets 10 tons per month while Japan's Spiber partners with 45+ brands. Explore Super Silk's potential in fashion, medicine, and defense, and how this bio-revolution is unfolding.
Citizen Electronics has built the first pressure sensor switch that also gives a physical click, reading 0.35 mm of travel across roughly 6,000 steps. Its metal spring tames hysteresis, the chronic flaw in pressure sensors, opening the door to analog game buttons and robot fingertips.
A Japanese research team from Fukui, Tohoku, Chiba, and Tokyo universities has theoretically proposed a new method to detect Majorana particles using spin currents. Not an observation but a proposal, it opens a fresh window onto the quasiparticle behind topological quantum computing, the same goal Microsoft's Majorana 1 chip pursues.
Chiba Prefecture sits atop an estimated 500-year supply of iodine, the key material in Japan-invented perovskite solar cells. If combined, they could form a fully domestic energy cycle. We break down the potential and the hurdles standing in the way.
Two wooden walls are bolted down and pulled against each other until one breaks. That is the Kabe-1 Grand Prix, where universities, construction giants and home builders compete for the title of Japan's strongest shear wall. Born after the 1995 Kobe earthquake, it doubles as a public destructive test. Here is how it works and how the 2025 tournament went.
Kyoto Institute of Technology and Chuo University have developed a cooling-free infrared sensor using semiconductor carbon nanotubes (CNTs) with 11x greater sensitivity than conventional materials. Building on Japan's legacy in CNT research since their 1991 discovery at NEC, this breakthrough could transform autonomous driving, security screening, and medical imaging. Here's what it means and how Japan is reacting.
As AI growth makes chip power consumption a critical global issue, Japan's next-generation chip technologies are drawing attention. Tohoku University's MRAM cuts power consumption to a hundredth of conventional chips, while the diamond semiconductors led by Saga University have hit 120 GHz operation and are heading toward space and 6G applications. A report on Japan's technological edge and the competition with the US and China.
No batteries. Just 280 grams of rubber. A Japanese bone-setter turned entrepreneur created "futto," a walking support device using rubber tubes as artificial muscles. Built with hardware store materials by a three-person family company, it now has peer-reviewed backing, a distribution deal with France Bed, and sales abroad. Here's how this $220 device answers a problem every aging society shares.
Beef tendon, a common Japanese hot pot ingredient, is being transformed into knee ligament implant material. A Waseda University startup has developed decellularization technology that could eliminate the need to harvest patients' own tissue for ACL reconstruction. Clinical trials are underway with commercialization targeted for 2028.
