What Top Engineering does

Top Engineering (株式会社トップエンジニアリング) is a Tokyo-based engineering services company founded in October 1993 and operating as a core subsidiary of Hirayama Holdings (Tokyo Stock Exchange Standard, ticker 7781). The company provides technical staffing and outsourced design and development services across mechanical design, electrical and electronic design, software development, IT infrastructure, plant design, and production technology, with 525 dispatched engineers serving 125 client business locations and a publicly disclosed 39.09% dispatch margin rate. Its customer base is concentrated in Japanese manufacturing across automotive (Nissan, Toyota), electronics (Sony, Panasonic), aerospace, semiconductor, robotics, and plant engineering, with sales offices in Tokyo, Nagoya, Osaka, and Fukuoka.

The company generates revenue through two primary streams: (1) engineering staffing/dispatch under Japanese labor dispatch law at usage-based daily billing rates, and (2) outsourced contract design and development projects covering R&D through production technology. Beyond staffing, Top Engineering layers on adjacent offerings including AI Solutions for manufacturing (computer vision for safety, defect, and anomaly detection), ARIGATO WORK (bilingual foreign-national engineer staffing acquired from Hirayama in July 2025), free DX reskilling courses for 50s/60s candidates, IoT systems, and participation in the Japan Deep Learning Association (GUGA).

The business model relies on direct enterprise field sales to place engineers at client manufacturing and technology sites, supported by recruitment marketing (corporate site, recruitment blog, job fairs, JR Yamanote Line advertising, e-sports sponsorship with FENNEL). Headcount stands at approximately 566 employees (with 77 new graduate hires in April 2026), and the group context provides distribution synergy via Hirayama Holdings' manufacturing and overseas operations. A planned absorption-type merger of Top Engineering into Hirayama Corporation is announced for January 1, 2027.
