What MouseComputer does

MouseComputer CO., LTD. is a Japanese Build-to-Order (BTO) personal computer manufacturer headquartered in Chiyoda, Tokyo, with primary production at a factory in Iiyama, Nagano Prefecture. The company designs, assembles, and sells customizable desktops, laptops, workstations, servers, and displays under six sub-brands: mouse (general consumer), G TUNE (gaming), NEXTGEAR (online/direct-store exclusive gaming), DAIV (creators and AI workstations), MousePro (business), and iiyama (displays). Customers configure CPU (Intel Core Ultra / Xeon, AMD Ryzen), GPU (NVIDIA GeForce RTX / RTX PRO Blackwell, AMD Radeon), memory, storage, and cooling at order time, with select models shipping from stock the next business day and high-end configurations (e.g., dual RTX PRO 6000 workstations priced above 8.7 million yen) targeting AI, deep learning, and professional visualization workloads.

The company operates a multi-channel go-to-market combining its own e-commerce platform, eight physical retail stores across Japan, third-party marketplace storefronts (Amazon Japan, Yahoo Shopping, Rakuten), and a dedicated corporate sales team. Revenue is generated primarily through hardware sales, supplemented by paid services such as extended warranties, Anshin Pack premium support, next-day shipping, on-site setup, data recovery, and PC trade-in. Marketing relies on the mouse LABO content platform, sports and esports sponsorships (DetonatioN FocusMe, Urawa Red Diamonds, Ryukyu Golden Kings, 2026 Asian Games), and event/venue advertising including MLB out-of-home placements. The company differentiates on domestic manufacturing quality, a 3-year standard warranty, 24/7 phone support, and a 72-hour average repair turnaround, supported by Intel Prestige Partner, NVIDIA Studio, and JESU esports certifications.
