What Open Up does

Open Up Group Inc. (株式会社オープンアップグループ, TSE PRIME: 2154) is a Japanese engineer dispatch and contracting group headquartered in Toranomon, Minato-ku, Tokyo. Founded in 1997 originally to employ people with disabilities, the company entered engineer staffing in 2004 via the acquisition of San-Ei Trading's manufacturing contracting operations and merged with engineer staffing peer Trust Tech in 2008; it has since been reorganized under the Open Up Group brand following the 2021 BeNEXT-Yumeshin Group integration. The group operates 16+ wholly-owned operating subsidiaries structured around three roughly equal segments: Mechanical/Electrical Engineering (機電), IT Infrastructure and Development, and Construction Engineering (建設), with additional adjacencies in disability employment BPO (Open Up With) and online IT education (SAMURAI).

The company recruits, trains, and dispatches engineers to client companies across manufacturing, IT, and construction. As of FY25, it fielded 24,466 engineers at a 93.9% utilization rate, supported by training centers (including a new Osaka facility), proprietary qualification exam seminars with QC pass rates 12+ points above national average, and an integrated AI/DX Platform that aggregates engineer data across group companies to support LTV analysis and deployment optimization. Customers include major Japanese manufacturers such as Hitachi and Nikon, with 657 engineers transferring directly to client firms in FY25.

Revenue is generated primarily through professional-services-style engineer dispatch fees and managed-services contracting arrangements, priced on a quote basis that varies by engineer skill level, segment, and project duration. FY25 net sales were ¥187.9 billion with operating profit of ¥16.2 billion (ROE 15.9%, ROIC 15.0% vs. WACC 6.5%). Distribution is direct enterprise sales across Japan, supplemented by wholly-owned HR and engineering subsidiaries in Indonesia, China, and Vietnam. The company markets through its corporate website, recruitment brand site, IR communications, and earned media coverage.
