Kansetsu CO

What Kansetsu CO does

Kansetsu CO (株式会社カンセツ) is a privately held Japanese engineering design services firm founded in December 1951 as Japan's first dedicated machine design company. Headquartered in Osaka with 17 offices nationwide, the company delivers outsourced mechanical equipment design, product development design, electrical control design, and software development design to major Japanese manufacturers across semiconductors, automotive, aerospace, steel, power generation, consumer electronics, and chemical/pharmaceutical processing. Service delivery occurs via two contract formats — business outsourcing (請負) for defined design deliverables and technical personnel dispatch (派遣) under labor dispatch license 派27-302610 — supported by a diverse multi-vendor CAD environment (AutoCAD, CATIA V5/V6, Inventor, SolidWorks, Creo, Solid Edge, MICRO CADAM, among others), CATIA-based structural simulation, and a 3D Systems ProJet 2500 Plus 3D printer for rapid prototyping.

As of April 2020 the firm employed 784 people, including a deeply credentialed technical bench of 505 first-level certified skilled workers (mechanical/plant drafting), 131 second-level mechanical design engineers, two professional engineers (技術士), and 30+ information processing engineers. It maintains a 7-year internal education program, embeds design staff at client sites (including a sub-office inside Nippon Steel's Setouchi Works), and serves 100+ corporate customers across diverse verticals.

The business model is B2B professional services revenue with negotiated per-project pricing, complemented by a Partner Company Model that recruits external companies and sole proprietors to expand delivery capacity. The company is family-controlled: founder Tanino Isamu led from 1951 until 1988 (and received the Yellow Ribbon Medal for contributions to Japan's machine design industry), with current Representative Director Tanino Tomotaka continuing that lineage. Kansetsu CO is the surviving entity of a 1984 merger of three group firms, and operates affiliated subsidiaries 株式会社ダイセツ (engineering) and カンセツ産業株式会社 (trading). Registered capital is ¥80 million; revenue is not publicly disclosed.
