What Eclipse does

Eclipse (株式会社エクリプス / Eclipse, K.K.) is a privately held Japanese IT services company incorporated on August 17, 2018, headquartered at Setagaya-ku, Sengenzaka 1-35-3 MT Building 202, Tokyo, Japan. The company operates three core service lines targeting Japanese internet-dependent businesses: an internet advertising agency (インターネット広告代理店) providing customer acquisition support via owned-media advertising slots and performance-based advertising technology; server maintenance and management (サーバ保守管理) covering remote monitoring, troubleshooting, regular backups, and security management; and system consulting (システムコンサルティング) covering 現状分析 (current-state analysis), countermeasures proposal, SEO optimization, website and smartphone application improvement, and new system construction. The three modules are marketed as a unified service portfolio rather than a modular platform.

Underlying technology is not explicitly disclosed in available sources. The company describes its advertising service as leveraging performance-based advertising technology and its server service as remote monitoring with backups, but no proprietary platforms, software stacks, APIs, or architecture details are published. Service delivery appears to be staff-led engagement work rather than productized software, with no mobile app, public API, SDK, or downloadable product offered.

The company is a privately held, founder/management-led corporation under Representative Director Mitsuru Onogawa (小野川 充). No investors, funding rounds, parent companies, subsidiaries, or public listing are disclosed. Pricing models, contract values, customer logos, and revenue figures are not publicly disclosed. In addition to its three core IT services, Eclipse discloses operation of an internet dating introduction business (インターネット異性紹介事業) under JAPHIC Mark Certification (認定個人情報保護団体) for personal information protection, indicating an additional regulated vertical in the company's portfolio. The customer base appears horizontal — small and mid-sized Japanese businesses seeking internet marketing, server management, or digital transformation consulting — and the company warns on its contact page about inbound inquiries confused with an unrelated sunglasses retailer of similar name.
