What INET does
INET (株式会社アイネット) is a privately held Japanese IT services company founded on March 24, 1993, and headquartered in Saitama City, serving enterprise clients across the Greater Tokyo metropolitan area. The company operates three integrated service lines: application development (covering initial impact analysis through design, coding, testing, and release), IT infrastructure design and construction (encompassing host systems, OS servers, cloud, virtualization, containers, middleware, databases, and networking), and system operations and maintenance (including mainframe and OS server management, monitoring, security, backup, database administration, helpdesk, and PMO functions). Application development teams of up to 20+ members deliver projects across mainframe, client-server, web, and mobile environments using Java, VB.net, C#.net, C/C++, COBOL, JavaScript, Python, and PL/SQL, with recent expansion to include AI API integration and modern web frontends.
The company's revenue model is anchored in professional services and managed/staffing services under a General Worker Dispatch Business Permit (派11-300981). Clients span social infrastructure, finance, manufacturing, distribution, and service industries, including manufacturer and telecom system vendors/integrators, independent system service companies, and financial and service industry system specialists. INET emphasizes long-tenured client relationships, with some continuous system operation contracts spanning approximately 25 years. Go-to-market is sales-led and direct, with services delivered primarily on-site at client locations in the Tokyo-Saitama area; marketing is limited to recruitment channels (Mynavi platform, Instagram, local job fairs). Notable operational metrics include an average of 10.3 hours monthly overtime (2024), 77% of system department employees working partially or fully remotely, an 88% equity ratio, and debt-free operations with ¥10 million registered capital.
INET maintains Privacy Mark certification (JIS Q 15001, registration 11820631) since 2006, the Saitama Prefecture Healthy Management Practice Business Office certification (April 2024), and is a certified Saitama Prefecture Senior Active Promotion Declaration Company. Leadership is stable, with President and Representative Director Hideaki Fujisawa (藤澤秀昭) at the helm since founding, supported by Directors Yuichi Hamasaki (濱崎勇一, Business Headquarters Head and Personal Information Protection Manager), Kenji Koiwa (小岩賢二, System Headquarters Head), and Hideya Fujisawa (藤澤秀哉), plus Auditor Hiroshi Yano (矢野豪士). The company is privately held with no parent company, no disclosed funding rounds, and no institutional investors identified.
