A paddy field in central Japan was swallowed by bright yellow flowers. Water primrose, a South American invader, regrows from the tiniest stem fragment. We look at why farmers cannot kill it, how the same plant is wrecking waterways in France, Britain and the US, and why eradication may be impossible.
Seven months after metal-organic frameworks (MOFs) won the 2025 Nobel Prize in Chemistry, where does the technology actually stand? A status check on Atoco's air-to-water devices, scaled-up carbon capture by Svante and Kobe Steel, China's lead in MOF research output, and why an Atomis executive says a Nobel does not lower the hurdles.
Eleven days, 44 countries, 400 delegates. We score the five expectations from our pre-meeting article against the MOFA outcome communique: emperor penguin protection blocked, tourism rules deferred, Annex VI stalled, only the transparency resolution delivered.
Roadkill of the Amami black rabbit, a 'living fossil' found only on two southern Japanese islands, hit a record 185 in 2025. The grim milestone is a side effect of Japan's celebrated invasive-species eradication programs — including a 24-year mongoose campaign declared complete in 2024.
A Japanese research team — University of Tokyo, JAMSTEC, and the National Institute of Polar Research — has produced the first direct observational evidence that warm-water microbes carried into the Arctic Ocean are altering its nitrogen and phosphorus cycles. Aboard the R/V Mirai between 2015 and 2020, they tracked how UCYN-A2, a nitrogen-fixing organism normally associated with subtropical seas, surged into the Arctic basin during the early ice-melt year of 2017 — and why that matters for the world's most rapidly warming ocean.
Calbee is switching 14 of its flagship snacks — including Potato Chips Lightly Salted, Consomme Punch, and Kappa Ebisen shrimp chips — to monochrome 'petroleum-saving packages' from May 25. The cause: ink shortages triggered by the Hormuz Strait crisis. A symbolic case of geopolitical risk reaching Japan's shelves, compared with parallel moves at Lindt, Lamb Weston and Smithfield Foods.
Between March and May 2026, Japan launched a wave of perovskite solar cell demonstrations across the country—world efficiency records, rice paddies, mountain tea fields, skyscraper windows, highway parking areas, and Toyota's Woven City. We unpack for international readers why everything is happening at once.
Japan's Resonac (formerly Showa Denko) will switch its Kawasaki ammonia plant to 100% waste-plastic-derived hydrogen by April 2030, ending its reliance on natural gas reforming. The world's only long-running commercial gasification chemical recycling plant processes 70,000 tons of plastic waste annually to produce 120,000 tons of ammonia, with 80%+ CO2 reduction. Now backed by Japan's first CCfD-style price-gap subsidy. A circular alternative to urban mining.
Tourist numbers up from 5,000 to 120,000 a year, sea ice at record lows, emperor penguins now Endangered. What ATCM48 in Hiroshima and Japan's Antarctic protection law amendment must confront.
Toshiba Energy Systems, Airbus, and Toyota are racing to commercialize superconducting motors that promise 10x the power density of conventional motors. Dubbed the 'ultimate motor,' the technology enables hydrogen aircraft and hydrogen-engine cars while leveraging Japan's decades of niche superconductor expertise. As eVTOL startups falter, why is Japan's aviation motor technology suddenly central to the global decarbonization race?
Susumu Kitagawa of Kyoto University, joint winner of the 2025 Nobel Prize in Chemistry, has long advocated turning air itself into a resource through metal-organic frameworks (MOFs). His porous crystals can sort and capture CO2, water vapor and other molecules, putting Japan in direct conversation with players like Switzerland's Climeworks in the rapidly evolving direct-air-capture industry. Here is how a basic-science breakthrough from Kyoto could rewrite the economics of decarbonization.
On March 25, 2026, five partners, NYK Line, NTT Facilities, Eurus Energy, MUFG Bank, and the City of Yokohama, launched a world-first floating data center powered entirely by solar panels and batteries at Yokohama Port. How does this off-grid demonstration differ from the MOL-Hitachi used-ship concept, and what does it say about Japan's answer to the AI power crisis?
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.
