A single fusion reactor needs about 10,000 km of high-temperature superconductor tape, and five years ago almost no one could make that much. Now four Italian physicists at startup Suprema are building Europe's largest tape plant to break in. But the companies that already dominate this wire are mostly Japanese: two of the four global fusion-grade producers are based in Japan. Inside the race over the thin ribbon fusion runs on.
Ultra-pure water is the invisible backbone of chipmaking, so clean that a stadium of it may hold less impurity than a single sugar cube. Three Japanese firms, Kurita, Organo and Nomura Micro Science, lead the world. We unpack their technical edge and the contest with global rivals like Veolia.
China overtook Japan in net external assets at the end of 2025, dropping it to third place — yet Japan's holdings hit a record high. Here is what the numbers really mean for the yen.
At the APEC trade ministers meeting in Suzhou, China, Japan's industry minister demanded that exporting countries rectify arbitrary rare earth curbs. A look at the slow squeeze on Japan, its roots in a Taiwan remark, and Tokyo's exit strategy.
Kawasaki Heavy Industries—maker of jets, bullet trains and motorcycles—has opened a physical AI development hub in Silicon Valley, teaming up with NVIDIA, Analog Devices, Microsoft and Fujitsu. We unpack why a 130-year-old industrial giant is betting on AI that acts in the real world, and where Japan stands in the US-China robotics race.
OpenAI is moving to offer its newest cyber-focused AI model, GPT-5.5 Cyber, to the Japanese government and industry. Former NSA Director Paul Nakasone, now an OpenAI board member, flew to Tokyo to pitch critical-infrastructure cooperation. We unpack the contrast with Anthropic's tightly controlled Claude Mythos, the China-threat framing, and what it means that OpenAI wants Japan as its first international partner.
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.
Hoku Energy K.K., the Japanese subsidiary of UK-based Hoku Infrastructure, will build Japan's first new-build 100% hydrogen mono-firing thermal power plant in Aomori Prefecture. The 106.6MW Daiichi Plant, awarded under Japan's 3rd Long-Term Decarbonized Power Source Auction, is scheduled to start operations in the early-to-mid 2030s. We compare it with hydrogen power efforts by Plug Power, MHI in Utah, Linde, Air Liquide, and South Korea's Doosan, and explain what it means for Japan's GX strategy.
On May 19, Japan's ruling LDP unveiled a policy proposal calling for stablecoins and tokenized deposits to be treated as national financial infrastructure — and added to PM Takaichi's Big-Boned Policy in June. We compare Japan's approach with the Web3 hubs of Singapore, Hong Kong and the UAE.
NEC has completed the East Micronesia Cable System (EMCS), a 2,250-kilometer optical submarine cable that gives three Pacific island nations their first-ever fiber connectivity. For Tarawa, Nauru, and Kosrae — roughly 100,000 people who had only known the 600-millisecond delay of satellite internet — the upgrade is transformative. The backstory is equally striking: in 2018, China's HMN Tech (formerly Huawei Marine) underbid NEC and Alcatel Submarine Networks by more than 20%. A 2020 US diplomatic warning to Micronesia, the World Bank's withdrawal, and a 2021 Japan-US-Australia rescue plan rewrote the project. Five years later, the cable is in the water.
Brazilian Foreign Minister Mauro Vieira visited Japan on May 17–19 for the inaugural Japan-Brazil Foreign Ministers' Strategic Dialogue. Here's what oil-dependent Tokyo wants from South America's resource giant amid the Hormuz crisis.
Kawasaki Heavy Industries has begun pitching a technology that produces naphtha—the building block of plastics—from hydrogen instead of crude oil. Built on its commercial gas-to-gasoline plant in Turkmenistan, the proposal lands in the middle of a Japanese petrochemical crisis triggered by the Strait of Hormuz disruption.
TSMC's Japanese subsidiary JASM posted a quarterly profit of NT$951 million (about $30 million / ¥4.78 billion) in Q1 2026 — the first time the Kumamoto fab has been in the black since mass production began in December 2024. We unpack what the 14-month turnaround means against the backdrop of Japan's ¥1.23 trillion in subsidies, the Sony-Denso-Toyota partnership, TSMC's Arizona and Dresden expansions, and Rapidus's high-stakes 2nm bet.
Anthropic's Head of Global Affairs Michael Sellitto arrived in Tokyo May 15 and confirmed the company is weighing participation in the cyber defense corporate alliance proposed by Japan's ruling LDP. Modeled on US Project Glasswing, the framework will test Japan's distinctive 'middle path' — an AI Promotion Law with no penalties, sitting between the EU AI Act's hard regulation and the deregulatory turn under the Trump administration.
The SI second hasn't changed since 1967. By 2030 it likely will. From Earth's rotation to atomic vibrations to optical transitions—this is the history of how we've defined the second, and a field guide to the candidate atoms and national labs racing to define it next.
PM Sanae Takaichi pledges to effectively double research funding and build a 'new technological nation,' targeting AI, semiconductors, and quantum to compete with the US, China, and Korea. We examine the reality behind the plan—Japan's 3.44% R&D-to-GDP ratio, declining PhD numbers—and whether the strategy can work.
Japan's ruling LDP is pushing to build a dedicated rare earth mining vessel for ~100 billion yen ($640M) at Minamitorishima. Here's why JAMSTEC's Chikyu isn't enough, the 2028 commercialization roadmap, and how Japan's strategy compares with US and EU efforts.
About 283,000 barrels of Azerbaijani crude procured by ENEOS arrive at Negishi Refinery in Yokohama on May 12 — the first Central Asian crude ever to reach Japan. We unpack the type of oil, Azerbaijan's production capacity, and the wider patchwork now stitched together from the US, Mexico, Russia (Sakhalin-2), and beyond — plus the paint-thinner shortage that won't go away.
Honda's Zero EV brand launches its first model—the 0 Alpha compact SUV—in India by early 2027, exporting back to Japan. After cancelling three North American EVs and posting record losses, Japan's #2 automaker is betting on Rajasthan over Ohio. We unpack the gamble, the rivals waiting in India, and why this could rewrite Japanese EV strategy.
At a Fireblocks event in Tokyo, SMBC Group CDIO Kazuho Isowa and Mitsui & Co.'s Shinsuke Waka outlined Japan's on-chain finance strategy. January 2028 will bring simultaneous tax and financial-law reforms. ZipangCoin is going cross-border on public chains. And 95% of JPYC trades are now executed by AI. We compare Japan's cooperative model with JPMorgan's $5 billion-a-day Kinexys.
