IVOO

What IVOO does

IVOO (株式会社ＩＶＯＯ) is a Tokyo-based private company founded in April 2013 by Oki Masaki (沖野正樹) that provides specialized employment support services for individuals with mental and developmental disabilities in Japan. The company operates a three-pillar service platform: in-house employment support (自社雇用) that helps enterprises recruit, onboard, and retain disabled workers; business outsourcing (アウトソース) under which IVOO operates satellite offices and remote environments employing disabled workers on behalf of client companies; and the proprietary iASIS (アイアシス) retention support system, launched in March 2022, which tracks and manages employee progress for client companies. Supporting modules include job coach dispatch (定着支援/ジョブコーチ派遣), recruitment and talent matching (人材紹介), return-to-work support (復職支援), and a training system (当事者研修システム) launched in July 2020 that integrates ChatGPT-based skills development.

The business model combines professional services fees (recruitment, consulting, job coach dispatch), managed services revenue from outsourcing/satellite-office arrangements, and subscription-like recurring revenue from iASIS system sales. IVOO serves Japanese enterprises needing to comply with statutory disability employment quotas (法定雇用率), with a disclosed client roster spanning an izakaya chain of approximately 1,900 regular employees (continuous engagement since 2013), a foreign-capitalized software company (~120 employees, since April 2025), a home builder (since November 2024), a geological survey firm (since December 2023), and a cafe chain (since April 2024). The company employs 8 staff including certified psychiatric social workers, social workers, and job coaches, operates from a Shinjuku headquarters and a Chuo satellite office, and maintains referral partnerships with employment transition support agencies plus a long-standing relationship with the Tokyo Labor Foundation (しごと財団) since 2014.

Customer acquisition combines direct enterprise field sales, free consultations, seminars at administrative agencies and medical institutions, and inbound referrals from vocational rehabilitation centers. The founder's personal connection to mental illness in his family underpins a 14-year specialization in mental and developmental disabilities — a narrower focus than general HR or staffing firms. IVOO remains privately held and founder-owned with no institutional investors disclosed; in November 2025 the company increased its registered capital to ¥10 million, indicating modest balance-sheet strengthening without external capital infusion.
