The company's core offering is fiber optic internet for residential and small business customers, delivered through a multi-carrier reseller model. It operates its own @T COM Hikari service via the NTT Hikari Collaboration framework, supplemented by reseller partnerships for au Hikari (KDDI), SoftBank Hikari, Docomo Hikari (NTT Docomo), and NTT Flets Hikari. The underlying network leverages JPIX v6 Plus IPoE technology for IPv6 connectivity, supporting speeds up to approximately 10 Gbps.

Revenue is generated through recurring monthly subscriptions across consumer and business fiber, mobile, and add-on services, with prices typically ranging from ¥1,760 to ¥6,600 per month and bundled with two-year auto-renewal contracts. Distribution is digital-first via the official website and LINE account, supplemented by phone-based customer service and carrier partner channels. Go-to-market emphasizes smartphone carrier set discounts (au Smart Value, Ouchiwari Hikari Set, Docomo Hikari Set Waru) and cross-selling into the parent TOKAI Group's existing energy and water customer base.
