Japan's Ministry of the Environment reports total waste of 38.11 million tons for FY2024 (down 2.2% YoY) with a recycling rate of just 19.3%. Why is Japan, famous for its cleanliness, so far behind Germany (67%) and South Korea (60%)? A look inside the world's most incineration-dependent waste system.
Microplastic pollution isn't limited to oceans — it's now raining down on forests too. A TU Darmstadt study first proved that airborne plastics settle on tree canopies and accumulate in forest soil. With 67% of Japan covered in forests, the implications are enormous. Japanese researchers have also pioneered breakthroughs in understanding how trees trap airborne microplastics.
Japan Research Institute proposes an Ocean Industrial Complex combining deep-sea robotics, rare earth mining, and blue carbon. With a successful trial extraction of rare earth mud from 6,000m depth and breakthrough underwater wireless tech, Japan's ocean strategy is becoming reality.
WWF Japan reveals shocking data on pet-origin invasive species, while Amami Oshima achieves the world's largest mongoose eradication. A deep dive into 20 years of Japan's invasive species law.
JAMSTEC research reveals microplastic density near Japan is 27 times the global average. An estimated 28,000 tons sink to the deep sea annually, and fishing-related plastic accounts for half of all coastal debris. Plus: the world's first ocean plastic center opening June 2026.
Itochu Corporation launches a joint venture with America's largest e-recycler ERI to tap Japan's urban mines for rare metals. With Chinese lithium giants also eyeing the market, we break down the business battle over Japan's hidden treasure trove of 6,800 tons of gold and 60,000 tons of silver.
Japan's steel industry accounts for about 40% of the country's industrial CO2 emissions. The government now aims to create a green steel market exceeding 3 million tons annually by the early 2030s, combining hydrogen reduction, electric arc furnaces, and CCUS. Here's how Japan plans to standardize carbon footprint metrics and respond to the EU's CBAM.
Japan's natto exports hit a record 5,248 tons in 2025, up 44% year-over-year. Driven by global health trends and fermented food hype, natto is conquering new markets. But packaging regulations and Korean competitors pose challenges. Plus: how the world eats natto.
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.
Rohm has achieved its NEDO-funded technical target for 8-inch SiC MOSFETs two years ahead of schedule, demonstrating over 50% power loss reduction versus conventional silicon IGBTs. We explore what this means for EVs, renewable energy, and Japan's power semiconductor consolidation race involving Toshiba, Mitsubishi Electric, and Denso.
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.
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?
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.
Toyota announces mass production of water electrolysis systems by 2029, developed with Chiyoda Corporation. With 5MW domestic and 20MW international units, Toyota bets on hydrogen alongside EVs and hybrids. How Japan's multi-pathway strategy compares to the global EV-first approach.
Asahi Kasei has begun installing its Aqualyzer C3 containerized alkaline water electrolyzer in Jyväskylä, Finland — the country's first commercial hydrogen station. Backed by a Toyota-linked foundation, this marks a significant entry for Japanese electrolyzer technology into the Nordic green hydrogen market dominated by European giants like Siemens Energy and Nel ASA.
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.
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.
Agro Ludens started mass-producing CoMeat, a rice-derived mycoprotein made with koji fermentation, at its Nasu plant in Tochigi in April 2026. It uses processing-grade rice, not table rice, and Japan's agriculture ministry approved mycoprotein as a new-market rice use in March. Plus: Japan's swing from rice shortage to rice glut, Beyond Meat down 99%, and why JR East is now farming.
Shibaura Institute of Technology and AIST have measured the stable carbon isotope ratios of PFOA and PFOS, a world first for PFOS, using an Orbitrap that reads the chemical fingerprint without burning the sample. River spike tests proved it works on real environmental water, opening a path to identifying PFAS pollution sources. The bench work was a senior thesis. Japan made its 50 ng/L tap water standard legally binding in April 2026.
