What StarCraft does

StarCraft (株式会社スタークラフト) is a Japanese digital marketing and affiliate media company headquartered in Toshima-ku, Tokyo. It is privately held, founder-led by Daigo Nakakura, and operates with a lean team of roughly 8 members.

The company's core product is the エリスグッド (ErisGood) lifestyle comparison media platform, which aggregates and evaluates Japanese consumer infrastructure services across three content verticals: Communication/WiFi (optical fiber, pocket WiFi, WiMAX, home routers, VPN), Mobile/Smartphones (budget SIM, smartphones, iPhone, overseas eSIM), and Daily Life (electricity, water servers). Content is produced under proprietary editorial guidelines and a 50-Point Flat Evaluation System that scores providers across ten categories with equal 5-point weights, along with a household electricity cost simulation tool, intended to provide transparent, manipulation-resistant rankings. A legacy water server comparison site, Mizu-Navi (水ナビ), launched in 2019, has been consolidated under the broader ErisGood property.

StarCraft monetizes through performance-based affiliate commissions earned when readers click through to partner service providers (telecom carriers, electricity utilities, water server companies) and complete sign-ups or purchases. Distribution flows via SEO-driven organic search, while the company participates in multiple Japanese affiliate networks including AccessTrade (Interspace Inc.), ValueCommerce, and Rentracks. The company generates no direct revenue from end users, which are individual Japanese consumers researching service purchases, and operates exclusively within Japan with no disclosed geographies, funding events, or AI/ML capabilities.
