What PC Koubou does
PC Koubou (パソコン工房) is a Japan-based specialty retailer and BTO (Build-to-Order) PC assembler operated by Unitcom Co., Ltd., headquartered in Osaka. The company sells customizable desktop PCs, notebooks, gaming PCs, creator workstations, business PCs, DIY components, peripherals, and certified pre-owned hardware under the iiyama PC umbrella brand and its sub-brands — LEVEL∞ and LEVELθ for gaming, SENSE∞ for creators, STYLE∞ for general consumers, and SOLUTION∞ for business and workstation buyers.
The core product is a BTO configuration platform allowing customers to specify CPU, GPU, memory, storage, OS, and peripherals with domestic Japanese factory assembly. Fulfillment is differentiated by same-day shipment for pre-configured inventory and 2-day delivery for customized BTO orders. Component supply relies on direct relationships with Intel, AMD, NVIDIA, and Microsoft, alongside partnerships with Western Digital, MSI, ASUS, GIGABYTE, Kingston, ZOTAC, ASRock, Seagate, and ELECOM. Service revenue is supplemented by extended warranties, trade-in/buyback, 24/7 phone support, 500-yen coin diagnostics, and subscription software resale (Microsoft 365, Adobe Creative Cloud, Zoom, Autodesk).
The business model combines a sales-led hybrid GTM: direct-to-consumer through approximately 70 nationwide retail stores (PC Koubou and Good Will) and the pc-koubou.jp web storefront, plus a dedicated B2B sales force of 50 corporate offices serving enterprise, government, and education customers with bulk procurement, rental, leasing, and managed deployment. Pricing is one-time purchase across entry (under 100,000 yen), mid (100,000-200,000 yen), high-end (200,000-500,000 yen), and enthusiast/workstation (500,000+ yen) tiers, augmented by member-only free shipping, coupons, points, and trade-in value up to 50,000 yen per Windows 10→11 migration. Marketing emphasizes streamer and esports collaborations (ZETA DIVISION, k4sen, ドズル社, RIDDLE, SPYGEA, etc.), AI-PC promotion (Copilot+, AMD Ryzen AI), and a free WEB member program. Revenue is not publicly disclosed.
