German drone maker Helsing has enlisted Japanese e-commerce and finance firm Rakuten to help finalize a deal to sell its unmanned systems to Japan's army, a spokesperson for Rakuten said on Monday. Japan's Ground Self-Defense Force is currently testing Helsing's HX-2 strike drone, as Tokyo looks to modernize its military and counter an increasingly assertive China. The field tests will run until the end of September, the spokesperson said. Helsing struck an "initial agreement" for the Japanese government to use its systems earlier this year, a spokesperson for the Munich-based company said, adding that the move was made possible by an unnamed "local brokerage partner." Japan's Ground Self-Defense Force did not immediately respond to a request for comment.

Rakuten Group is working with defense AI startup Helsing to bring the German company's military drones to Japan. The Tokyo-based online shopping mall operator served as the point of contact between Helsing and the Japanese government, according to a Rakuten spokesperson. The country's Ground Self-Defense Force will conduct field tests of Helsing drones through the end of September, he said, without providing further details. The tie-up, which would be one of Helsing's first partnerships in the Asia-Pacific region, was first reported by the Nikkei. Japan, which for decades restricted arms exports, has been stepping up defense spending, and the country's companies have followed suit. E-commerce pioneer Rakuten has shifted some of its focus to the sector: It's partnered with a Ukrainian government agency to develop defense technologies, while subsidiary Rakuten Mobile has taken part in joint U.S.-Japan military trials of mobile technologies.

Can robots save an aging Japan? A mechanical wolf robot used to ward off bears and wild boars at a cabbage farm in the village of Shimo Higashiyama, in Yamagata Prefecture. It's hard to explain why Japanese love the cherry blossoms, called sakura. Robots do not appreciate the soft evanescence of the sakura. Nor do they understand why a snowbound town in northern Japan has dedicated itself to the cultivation of a winter variety. But the residents of Nishikawa have discovered -- at least, they thought they had discovered -- that they need robots for their sakura.

Japan's AI gamble: Can technology offset the cost of an ageing society? Beneath the business towers of Tokyo's Otemachi district, a test is taking place to see whether artificial intelligence can help solve one of Japan's biggest economic challenges: a shrinking workforce. Deep underground, Marunouchi Heat Supply Company operates a 30km (18.6-mile) network of heating and cooling pipelines serving offices, commercial buildings and transport facilities in one of Japan's most important business areas. The company is now using AI to manage this complex infrastructure with the goal of moving towards more automated operations by 2027. Developed with the Tokyo-based AI company Preferred Networks, the project uses PlantPilot, an AI system trained on historical operating data and the expertise of experienced engineers.

"We can't help thinking that the boom in generative AI-related stocks is about to end," an official of a bank-affiliated securities firm said.

Chipmaker Kioxia's market value halves from peak on AI selloff Kioxia overtook auto giant Toyota in market cap value in mid-June, but its ranking has since dropped to the fourth-largest Japanese company, as traders grow more critical over artificial intelligence. Japanese memory chipmaker Kioxia Holdings' market capitalization halved in just a month since becoming the nation's most valuable company, on growing concerns the artificial intelligence-driven rally in the sector has gone too far. Kioxia shares tumbled as much as 16% in Tokyo's morning trading on Friday, down 52% from last month's peak and losing at least ¥30 trillion ($185 billion) in value. In mid-June, Kioxia overtook auto giant Toyota in market cap value after the stock rallied more than 600% from the start of the year, driven by exuberance about demand for memory and data storage amid an AI boom. Its ranking has since dropped to the fourth-largest Japanese company. "The chip sector is vulnerable to the silicon cycle, and we've seen this pattern many times before," said Yugo Tsuboi, chief strategist at Daiwa Securities.

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.
