Green City

What Green City does

Green City Com Co., Ltd. (グリーンシティコム株式会社) is a privately held regional cable television and telecommunications operator headquartered in Owariasahi City, Aichi Prefecture, Japan. Founded on April 3, 1991 and commencing service in November 1992, the company holds a Cable Television Broadcasting Equipment Permit (1991) and a Type 1 Telecommunications Business license (1999). Its licensed service territory covers three municipalities — Nagoya City Moriyama Ward, Owariasahi City, and Seto City (with some areas excluded) — representing a single, geographically bounded franchise market.

The company's core product is the Green Hikari (green光) triple-play platform, combining fiber-to-the-home internet at 1 Gbps, 2 Gbps, and 10 Gbps tiers, multi-tier cable television including 8K/4K support and satellite broadcast relay, and fixed-line telephone via two carrier brands (Cable Plus Phone with KDDI and Cable Line with SoftBank). Supporting infrastructure includes G-PON fiber, LAN wiring, EoC over coaxial, Wi-Fi EasyMesh, MVNO mobile service, and the proprietary Soramame Channel (12ch/11ch) for local community programming. Third-party VOD services (Hulu, DAZN, FOD Premium), remote PC support, and B2B services (video production, event hosting, CM production, advertising) round out the portfolio.

Green City generates primarily recurring monthly subscription revenue from residential triple-play bundles (¥5,005–¥11,880/mo depending on speed and campaign terms), supplemented by one-off project revenue from enterprise, local government, and organizational clients (¥33,000–¥330,000 per project). Distribution combines direct sales through a physical storefront (Green City Plaza near Owariasahi Station), a call center (0120-150-676), a self-service website with billing simulation, mobile carrier reseller channels (SoftBank/Y!mobile, au/KDDI), and property-owner partnerships for bulk apartment deployments. The company is led by Representative Director Keiji Hatta (八太 敬二).
