What RENAC does

RENAC Corporation (株式会社レナック) is a Tokyo-based private software development and IT staffing firm founded on September 25, 1990, and currently headquartered in Shinagawa-ku. The company generates revenue through three professional services streams: custom business application development, labor dispatch of IT personnel (PM, SE, PG) under Ministry of Health, Labour and Welfare license 特13-305696, and consulting for logistics and real estate sales management. A small SEO/MEO service line is also offered, though it is not documented with customer evidence.

The firm's technical capability spans a wide programming language portfolio: legacy mainframe and office computer systems (COBOL, PowerBuilder, Developer2000) through to modern client-server and web architectures (Java including Applet, JSP, Servlet and EJB; .NET; C/C++; Visual Basic; PL/SQL; JavaScript; ASP; Perl; PHP; XML). Its case-study portfolio covers mainframe property search and accounts receivable systems, office computer fixed asset and municipal payroll systems, and a range of client-server/web deployments including a health insurance union cafeteria plan, electronics manufacturer internal logistics and management systems, a government shipping notification system, a real estate sales management system, and an air traffic control system. Registered capital is 10 million JPY, and the company reports a headcount band of 1-10 employees with no venture, private equity, or institutional investor involvement disclosed.

RENAC's go-to-market is direct B2B sales and consulting engagement, primarily to Japanese corporations and government organizations in the Tokyo metropolitan area. There is no documented digital marketing presence, no social media presence, and no app store footprint. Compensation for dispatched or contract engineers is publicly disclosed at 3,000,000 to 8,000,000 JPY annually; full-time SE starting compensation at age 25 is 270,000+ JPY per month and at age 30 is 300,000+ JPY per month, with PG starting at 210,000+ JPY (age 20) and 240,000+ JPY (age 25). President and Representative Director Shoji Kosaka (小坂省二) has led the firm since its founding, and Sumitomo Mitsui Banking Corporation serves as main trading bank.
