Konami has sued in California over the leaked Metal Gear Solid 2 source code that surfaced on 4chan. The real target: the anonymous leaker. We break down what leaked—9/11-era cut scenes, a phantom Wii port—why Konami is suing, and how it stacks up against past game-industry leak responses.
Japan's government and three megabanks gained access to a frontier AI model for cyber defense, with the digital minister calling to expand it to critical infrastructure. Set against the new US executive order and the EU AI Act, here is how Tokyo's approach differs.
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.
Yokohama National University spinoff LQUOM has closed a 1.23 billion yen ($7.7M) Series B to build quantum repeaters, the missing piece of the quantum internet. Here is what that means, and how it stacks up against Aliro in the US, USTC in China, and Japan's planned Tokyo-Osaka quantum backbone.

But similar PM-led intelligence bodies overseas have produced both spectacular successes (foiling the 2006 transatlantic bombing plot) and deep abuses: Korea's KCIA election interference, NSA mass surveillance, GCHQ's legal loopholes, BND monitoring German politicians for the NSA. What lessons should Tokyo draw?
