What Tsukumo does

Tsukumo (ツクモ) is a Japanese specialty PC retailer and Built-to-Order (BTO) custom PC manufacturer, founded in 1947 and headquartered in Tokyo, with operations consolidated under its parent company YAMADA-DENKI Co., Ltd. The company operates an omnichannel distribution model comprising seven to eight physical retail stores across Japan's largest metropolitan areas — Tokyo (3), Osaka (1), Nagoya (2), Fukuoka (1), and Sapporo (1) — alongside a nationwide e-commerce platform at shop.tsukumo.co.jp offering 24-hour shipping on stocked items, free shipping over ¥3,300, and multiple payment integrations including PayPay, Paidy installment payments, Amazon Pay, and d Payment via Sagawa Express logistics. The product portfolio is anchored by two proprietary BTO brands: G-GEAR for gaming PCs (with sub-lines including White Edition, Pillar-less showcase chassis featuring glass side panels and water cooling, G-GEAR mini compact form factor, and Powered by ASUS co-branded configurations) and eX.computer for standard, creator, and workstation systems (including the AeroStream mini-tower and pro-GPU Quadro-based workstation lines).

Beyond proprietary BTO systems, Tsukumo retails third-party PC components — Intel Core Ultra and AMD Ryzen CPUs, NVIDIA GeForce RTX 50-series and AMD Radeon graphics cards, motherboards, memory, SSDs, HDDs, cases, power supplies, cooling solutions — as well as peripherals, gaming accessories, Apple Mac products, gaming consoles, home appliances, AV equipment, software, and VR hardware. A dedicated corporate sales division (法人営業所) handles B2B volume procurement with a separate online quotation system, while a used-PC trade-in service (中古PC買取) feeds a certified refurbished NEC Refreshed PC program sold with manufacturer warranty. Co-branded product lines with ASUS, Corsair, Realforce, and licensed character collaborations (Hatsune Miku with Crypton Future Media, Gundam with Bandai Namco) extend merchandising into enthusiast and fandom segments.

Revenue is generated almost entirely through one-time hardware sales at unit-based pricing that spans entry-level BTO builds at ¥194,980 to high-end configurations exceeding ¥800,000, alongside component resale, peripheral sales, refurbished PC sales, and B2B bulk orders; the ツクモネット membership program unifies loyalty points across online and physical store purchases to drive repeat behavior. The primary customer segment is Japanese PC enthusiasts and gamers, with secondary segments in content creators, general consumers, corporate/B2B buyers, and budget-conscious refurbished-PC purchasers; the go-to-market is direct-to-consumer through both owned e-commerce and physical retail, supplemented by a dedicated B2B direct-sales motion. Pricing model is pay-as-you-go unit pricing rather than subscription or licensing, and no software, platform, or AI service revenue stream is disclosed.
