Nintendo shares climbed as much as 6.8% in Tokyo Tuesday to mark a third straight day of gains -- their longest winning streak since mid-March. Embattled Switch 2 maker Nintendo enjoyed its biggest stock gain in two months on Tuesday as concerns about overvaluation in the AI sector sent investors on the hunt for bargains elsewhere. Nintendo shares climbed as much as 6.8% in Tokyo to mark a third straight day of gains -- their longest winning streak since mid-March. The advance is part of a broad rally in Japanese video game stocks that saw Bandai Namco Holdings and Konami Group rise more than 9% on Tuesday. The revival in Japanese gaming shares comes after months of headwinds brought on by a memory chips supply crunch and worries it will hit hardware sales.

ANA President and CEO Koji Shibata speaks during a news conference in Tokyo on April 30. Many major Japanese companies, namely electronics makers, enjoyed rosy earnings in the year ended in March thanks to significant artificial intelligence-linked investment worldwide, but they are looking ahead with caution amid high costs for fuel and materials spurred by the war in Iran. Chipmaker Kioxia saw its group net profit double from the previous year to an all-time high of ¥554.4 billion ($3.48 billion). President and CEO Hiroo Ota described the financial performance as a "historic feat." Kioxia benefited from rising demand for memory chips amid a rush to build more data centers due to the growing use of AI.

The building that houses Recruit Holdings' headquarters in Tokyo. Investors have shown confidence in Recruit's HR Technology unit, where Indeed is leveraging AI to improve matching and raising average revenue from each job posting even as hiring demand remains soft. Recruit Holdings shares climbed the most on record after the Japanese owner of Indeed.com The stock jumped as much as 19%, its biggest intraday increase since the company went public in 2014, even as the Topix index fell, after issuing an outlook for ¥787 billion ($5 billion) in operating profit on ¥4 trillion in sales for the fiscal year to March 2027. That exceeds analysts' average projection for ¥723 billion and ¥3.9 trillion, respectively.

Shares are up more than 300% this year for the Tokyo-based company. Kioxia Holdings' shares were untraded in a glut of buy orders Monday morning after the supplier of storage for artificial intelligence data centers reported soaring profit and gave an outlook that trounced expectations. The Tokyo-based company said it expects to earn an operating profit of ¥1.3 trillion ($8.2 billion) during the June quarter, above the record profit it earned for the full year ended March. Its quarterly profit also surged past expectations, surpassing that of Toyota's, making Kioxia one of Japan's most profitable businesses. Kioxia's shares are up more than 300% this year.

SoftBank Group has reported a surge in quarterly profit due to valuation gains on its OpenAI investment, boosting confidence at the Japanese company to bet even more on the ChatGPT-maker. The gains on OpenAI outweighed lackluster investment gains elsewhere in the Tokyo-based technology group's portfolio while war in the Middle East roiled markets. That points to growing reliance on the U.S. startup, which faces rising competition from Anthropic and Google and is reportedly trailing its highest internal targets. SoftBank earned a net income of ¥1.83 trillion ($11.6 billion) in its fiscal fourth quarter, compared with the average analyst estimate of ¥295.2 billion. The profit could be attributed entirely to its booking $25 billion in valuation gains on OpenAI in the quarter, according to Bloomberg Intelligence analyst Kirk Boodry.

This'anti-goal' prompt trick keeps ChatGPT from going rogue A simple prompt structure using XML tags can stop ChatGPT, Claude, and Gemini from doing things you never asked for. All too often, ChatGPT, Claude, and Gemini overstep their instructions because they're so focused on making you happy. For example, an AI may jump ahead and completely rewrite a document when all you wanted was some focused feedback, or it may draft a brand-new recipe when you just wanted help substituting an ingredient. You might think the solution is to tell the AI chatbot what it do in your prompt.

A Maholo humanoid robot carries out a series of tasks at the Institute of Science Tokyo's Robotics Innovation Center, during the center's opening last month. Artificial intelligence is transforming the way we work across industries. Two recent developments in Japan show how technology could help the nation cope with a shortage of talent in the fields of science and medical research. Some researchers have launched an effort to deploy AI-powered robots to carry out complex wet-lab experiments, which could free staff from time-consuming, repetitive work. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

Japan Airlines says it will trial humanoid robots as workers at Tokyo's Haneda Airport, with tasks including baggage handling and cabin cleaning.

AI models surpassed the highest score recorded for a human test taker in this year's University of Tokyo entrance exam, a new study shows. If an artificial intelligence model such as ChatGPT had taken the entrance exams for Japan's top university in 2026, it would have been assessed as top of the class and admitted for scoring higher than any human test takers, a study by AI startup LifePrompt has found. The research used three major AI models -- ChatGPT 5.2 Thinking by OpenAI, Gemini 3 Pro Preview by Google and Claude Opus 4.5 by Anthropic -- and had them take the actual entrance exam used by the University of Tokyo in February 2026 to assess candidates for courses set to start in April. The university's category 3 science exam, often taken by those who want to enter the institution's medical school, is considered the most difficult exam to pass in Japan. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

Beijing's insistence that Meta unwind its deal with a Chinese A.I. start-up marks an escalation in the geopolitical fight over advanced tech. TAIPEI - Manus, an artificial intelligence startup, began with an idea among three engineers in Wuhan, China, united by an obsession with AI and a shared ambition to build a global venture. From the outset, they looked beyond China. Their big break came in March last year. Manus had drawn the attention of Silicon Valley investors with an AI agent capable of carrying out tasks on its own.
