What 株式会社スリー・イー does

株式会社アイデム (AIDEM Inc.) is a Japanese recruitment advertising and employment placement services company founded in 1981 and headquartered in Shinjuku, Tokyo, with regional offices in Osaka and Nagoya. The company operates the "アイデムエージェント転職" (AIDEM Agent Job Change) full-service placement agency, targeting mid-career professionals, new graduates, and foreign workers. Over more than 40 years of operation, AIDEM has built relationships with over 250,000 client companies and employs approximately 600 corporate sales representatives, supported by career advisors who conduct one-on-one consultations with candidates across Japan.

The core technology is a human-resources matching platform that combines a web-based self-registration flow, career-advisor consultations, and a proprietary database of non-public job openings. AIDEM states that approximately 90% of introducible positions are not publicly advertised, which functions as the primary differentiator versus general job boards. The platform supports vertical specializations including advertising/internet, IT/engineering, pharmaceuticals/medical devices, construction/facilities, apparel/consumer goods, sales/marketing, HR/administration, and healthcare professionals. Adjacent brands include AIDEM Global (foreign worker recruitment), AIDEM Agent Shinsotsu (new graduate placement), and a network of related job boards (e-AIDEM, Job Gear Career, Shigoto Joho AIDEM print free paper).

The business model is a complete success-fee placement model (完全成功報酬型): job seekers use the service free of charge, while client companies pay an introduction fee only after a candidate successfully joins. Distribution combines self-serve web registration for candidates, inside sales via career advisors, and a 600-representative field sales force for SMB corporate clients (primarily 1-500 employee companies). The company holds a Privacy Mark certification from JIPDEC and is certified as an excellent employment placement business operator under the Workers Dispatch Act by Japan's Ministry of Health, Labour and Welfare. AIDEM has been a J.League top partner since 2005 and has held over 55,000 cumulative job support seminars.
