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.
Mazda launched the third-generation CX-5 in Japan on May 21, 2026, starting at 3.3 million yen (around $20,800). With 5 million sold globally, this redesigned SUV is Mazda's bet on hybrids and combustion as the EV boom cools, and how it stacks up against Toyota RAV4, Honda CR-V, Tesla, and BYD.
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.
Fujitsu's new Kozuchi Physical OS isn't trying to build a smarter robot brain. It's trying to make the whole physical space intelligent. Here's how its edge-plus-sovereign-cloud design differs from NVIDIA Cosmos and Google DeepMind's Gemini Robotics — and how it fits into Japan's $126B Physical AI ambition.
An Osaka University team has shrunk a key step in magnetic tunnel junction fabrication from hours to about 1.7 seconds using flash-lamp annealing—up to thousands of times faster than conventional methods, with implications for MRAM mass production and flexible sensors.
Kyoto University spinout Toregem Biopharma will begin Phase 2 trials of TRG035, the world's first tooth-regeneration drug, in summer 2026, dosing 24 children with congenital tooth agenesis. A pre-Series C round of ¥850 million brings cumulative funding, grants included, past ¥4.6 billion. A look at how Japan's university-biotech funding stack works, and why a super-aged society may produce this kind of innovation first.
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.
Caviar's definition of 'best' has shifted from geography to aquaculture technology. As China supplies 60% of the world's farmed caviar and Russian product disappears under sanctions, a landlocked Japanese prefecture is challenging the global hierarchy with a hybrid land-based farming system that combines patented closed-loop tech with rare ultra-soft spring water.
Why a Nissan deep in restructuring picked Red Hat for its next-generation in-vehicle OS. We unpack the trap of in-house software development that cost Volkswagen's CARIAD 14 billion euros, and the path Nissan chose to avoid it.
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.
A black, sponge-like slab that floats with just lamp light has racked up 1.8 million views in a week. Developed at Nagoya University by Tomonaga Ueno, the carbon-nanotube aerogel is lighter than air and could quietly reshape EVs, eVTOL aircraft, drones and spacecraft. Here's how it actually works, and why the startup Sora Material thinks it's an industrial workhorse, not just a viral trick.
