Japanese PC maker Mouse Computer has laid out its business strategy and product roadmap for the second half of 2026 to the press. The headline is an "AI mini PC" designed to run large language models (LLMs) on your desk. It promises enough performance to handle models on the scale of 100 billion parameters without relying on the cloud, packing up to 128GB of memory into a compact chassis. The company also outlined plans for affordable mini PCs and a sub-1kg lightweight notebook, rolling out a distinctive lineup over the coming months.

An "AI Mini PC" That Runs LLMs Locally Takes Center Stage

The clear focus of the roadmap is a mini PC built squarely around local AI. Mouse Computer said an "AI mini PC" capable of running LLMs on the order of 100 billion parameters (the parameter count indicates a model's scale, with higher numbers pointing to more capable processing) will be one of the pillars of its late-2026 lineup.

A specific model is the "DAIV CX," a high-end machine with up to 128GB of memory in a compact body, slated for August. Because the size of model an LLM can handle depends heavily on memory capacity, fitting large amounts of memory into a small chassis is a configuration aimed squarely at people who want to run AI locally.

NVIDIA's Japan representative, who also serves as a vice president at its U.S. headquarters, joined the event. In a conversation with Mouse Computer's president, the two discussed how the compact AI development machine "NVIDIA RTX Spark" and local AI are reshaping the way people use PCs, underscoring that running AI on your own desk is becoming a new battleground for mini PCs.

Affordable Mini PCs and Lightweight Notebooks for Differentiation

Against a backdrop of steadily rising PC prices, Mouse Computer is emphasizing affordability. The NUC-style mini PC "mouse CA" can be configured with chips such as the Ryzen 5 3501U/6600H or Ryzen 7 H255, and features a simple design that fits naturally into a living room. Rather than chasing raw performance, it is positioned as an accessible, budget-friendly option.

On the business side, the company plans to launch a mini PC built on an all-new concept in October, alongside its existing "Mouse Pro CR." In the mobile space, the "mouse X2," a 12.1-inch Copilot+ PC weighing under 1kg, is planned for autumn or later, and the company is also preparing a 12.2-inch lightweight notebook that comes in under 1kg.

Gaming and Creator Lineups Refreshed Too

In gaming PCs, a strength of the company, it showcased the "G TUNE PG-A7G80," combining a Ryzen 7 9800X3D, a GeForce RTX 5080, 32GB of memory, and a 2TB SSD. It is the model being supplied in 100 units to a national high-school esports tournament and the 20th Asian Games. For entry-level buyers, the "NEXTGEAR J5" pairs a 15.6-inch high-refresh display with an RTX 3050 to keep the price down.

The creator-focused DAIV series is also expanding. The "DAIV Z5," a Copilot+ PC, packs a Core Ultra 7 356H and an RTX 5070 (8GB) into a thin, light 15.3-inch body measuring 15.9mm thick and weighing 1.54kg. On the display front, the company is lining up dual-mode LCD panels that switch by use case, OLED panels, models certified to Pantone's color standards, and panels supporting the DCI-P3 standard used in film production. A major new gaming desktop was also teased at the venue.

Record Earnings and a Return to "Monozukuri"

Behind this aggressive plan are strong results. Revenue for fiscal 2025 hit a record 73 billion yen, up 12% year over year, with PC shipments at 108% and display shipments at 104% of the prior year. Consumer PCs grew to 113% year over year, while corporate PCs and iiyama-brand displays reached 114%, all solid figures.

At the same time, fiscal 2026, which began in April, brings challenges such as parts shortages, rising prices, and an expected drop in replacement demand after Windows 10 reaches end of support. President Hideki Todoroki laid out five themes, including turning value into sales and share and ensuring quality and delivery through systems, signaling a strategy anchored in the strengths of a Japanese maker that produces and supports its products domestically. The company has also set up a new department to promote reuse and recycling, expanding affordable, dependable options through "Mouse refurbished PCs."

Summary

Mouse Computer's second half of 2026 centers on an "AI mini PC" that runs local LLMs on the scale of 100 billion parameters and the 128GB-memory "DAIV CX," with a broad refresh spanning affordable mini PCs, lightweight notebooks, gaming, and creator machines. In a market of relentless price increases, how it balances its domestic-production strength with accessibility will be the story to watch in the months ahead.
