Mouse Computer has introduced the X2, a lightweight and compact Windows 11 notebook featuring AI capabilities, upgradeable memory, and extensive connectivity, exclusively launching in Japan with potential future imports.
Mouse Computer has unveiled the X2, a compact Windows 11 notebook built around a 12.2-inch 1920 x 1200 display and a chassis that weighs 981g. The machine is aimed at users who want a very portable laptop without giving up the kind of connectivity and upgrade flexibility often removed from smaller designs. According to Japanese reports, the model also carries Copilot+ PC support on its Ryzen AI variants.
The X2 is offered with three AMD processor choices. At the entry point is the Ryzen 5 216, followed by the Ryzen AI 5 340 and the Ryzen AI 7 350. That spread gives Mouse a way to serve both lower-cost buyers and users who need more headroom for heavier multitasking or on-device AI features.
Despite its size, the laptop is unusually well equipped. Coverage from Japanese and international tech sites says the X2 includes Gigabit Ethernet, Wi-Fi 7, Bluetooth 5, HDMI, USB Type-A ports and a microSD card slot. It also has a 2-megapixel webcam with a physical privacy shutter, Windows Hello facial recognition, and a 180-degree hinge that lets the screen lie flat.
Battery capacity is set at 60Wh. Mouse says that translates to about 12.5 hours of video playback or roughly 25 hours at idle under JEITA 3.0 testing, though real-world results will vary. The display is reported to cover 100% of the sRGB colour space, and the chassis has been tested to MIL-STD-810H standards.
One of the X2’s more notable features is its upgrade path. The machine ships with 16GB of RAM in a single-channel layout, but one SODIMM slot is left open, allowing users to expand to 32GB with a compatible DDR5-5600 module. That approach is uncommon in thin-and-light laptops, many of which rely on soldered memory.
For now, the X2 appears to be a Japan-only launch. Sales are scheduled to begin in October through Mouse Computer’s Japanese online store, with pricing in local reporting starting at ¥199,800 for the base model and rising to ¥259,000 for the top Ryzen AI 7 configuration. For buyers outside Japan, that leaves import channels as the only immediate option, along with the usual questions over shipping, duties and warranty support.
