A facial recognition system has been introduced at ticket gates at Ikebukuro Station on the Tobu Tojo Line in Tokyo. Hitachi and Tobu Railway on Wednesday introduced a facial recognition system at ticket gates at Ikebukuro Station in Tokyo's Toshima Ward. Passengers can pass through the ticket gates hands-free if they register their facial data and commuter pass information in advance. The companies hope to encourage other railway operators to adopt the system, which can be installed by simply adding cameras and other equipment to existing ticket gates. The system was jointly developed in cooperation with three ticket gate manufacturers, including Toshiba. This is the first time that the system has been installed at a major terminal station in Tokyo.

Masayoshi Son speaks at an annual SoftBank World event in Tokyo on Tuesday. SoftBank Group founder Masayoshi Son said that in the not-so-distant future, nuclear fusion technology will offer the most realistic solution for powering AI data centers' ballooning needs. Natural gas will provide the bulk of data centers' power needs for the time being, Son said Tuesday. But he predicted that nuclear fusion -- the process by which the sun and other stars generate energy -- has a role to play, predicting the world will need 3 terawatts of data center capacity in 2040. Many technological and financial challenges remain for fusion technology to become a viable energy source, however, according to BloombergNEF. "Fusion will become the main source of a new kind of cheaper, clean and safe energy here on Earth," said Son, 68, at an annual SoftBank World event in Tokyo.

A dog has been rescued from Ben Nevis after it is suspected to have fallen ill from eating discarded cannabis. Christina Bluhme, a dog trainer from Esher in Surrey, was halfway up the UK's highest mountain when her black Labrador Tokyo collapsed on the trail. Lochaber Mountain Rescue Team came to their aid and stretchered Tokyo down from the 4,413ft (1,345m) peak to a local vet. Bluhme said Tokyo had made a full recovery after the incident during a trip to Scotland last weekend. She said vets believe she ingested cannabis left on the trail.

Smoke rises from an oil refinery following a Ukrainian drone attack on Moscow last month. Kremlin insiders say recent Ukrainian strikes have strengthened Russian President Vladimir Putin's resolve to keep fighting. Russian President Vladimir Putin is rejecting calls to negotiate peace with Kyiv, three sources close to the Kremlin said, with Ukraine's recent drone strikes on Russia's oil refineries and ports strengthening his resolve to keep fighting for now. Two of the sources, speaking on condition of anonymity, said that Putin was instead likely to escalate the conflict, now well into its fifth year. One of them, who meets regularly with the president, described a "high probability" of escalation in the coming months.

Such AI-generated content attracted approximately 335 million views on social media, resulting in financial losses estimated at ¥2 billion to ¥4.5 billion for celebrities and artists, according to the study. The estimated losses were calculated based on licensing fees related to using a person's likeness or voice, as well as the advertising value of view counts. However, the nonprofit added that the "actual financial losses might be significantly larger than the estimate," as the calculation only covered cases they were able to find. Only 1.1% of companies said they had guidelines on how to deal with these violations. Some 52% said they were "currently considering" options, while the rest had no plans as of date.

Since their listing in 2024, Kioxia's shares have surged on runaway demand for AI memory chips. Bain Capital has sold its entire stake in flash memory chipmaker Kioxia Holdings, closing a chapter on a deal that's transformed the Japanese tech and investment landscape. "We don't have a stake any more in Kioxia," Bain Managing Partner David Gross said in an interview. The U.S. private equity firm has logged record-setting returns after a global spending spree on AI catapulted Kioxia's shares more than 4,800% from their debut, transforming the chipmaker into one of Japan's most valuable companies. "It's worked spectacularly for all the stakeholders involved," Gross said.

China had previously restricted the import of Nvidia's H200 chips on concerns that a flood of American-designed AI processors would hinder the government's long-held goal of developing an indigenous chip industry. China plans to allow its top artificial intelligence companies to buy a limited number of H200 chips from Nvidia, a sign the country is easing restrictions on the coveted U.S. technology, according to The Information news site. Chinese officials have informed companies such as Alibaba Group Holding, ByteDance and DeepSeek that they will have permission to purchase some of the processors, which are used to develop AI models, the news site said Wednesday. The companies need to say how many chips they need -- and why -- to get approval, according to The Information. The chips have emerged as a geopolitical flash point for the world's two largest economies.

Japan's Terra Drone plans to set up a system enabling domestic production of up to tens of thousands of interceptor drones a year, the company's head, Toru Tokushige, said in a recent interview. As well as domestic development for such defense drones, the Tokyo-based company aims to speed up work to establish supply chains that do not rely on imports by promoting the development and production of drone components at home. In March, Terra Drone announced its full-scale entry into the defense drone market, in addition to civilian-use drones. As part of the move, the company has acquired two Ukrainian firms that develop interceptor drones. In Russia's invasion of Ukraine and the Middle East conflict, cheap drones are said to have changed the concept of war by shooting down expensive missiles and attacking important enemy bases.
