What KYOKKO SEIKO does

KYOKKO SEIKO Co., Ltd. (旭光精工株式会社) is a privately held Japanese precision machinery manufacturer founded in 1944 and headquartered in Kyoto, operating four factories across Kyoto, Yasu (Shiga), Toyokawa (Aichi), and Kochi — the last via wholly-owned subsidiary Kochi Kyokko Seiko. The company employs approximately 120–136 people (Japanese site reports 120; English site reports 136) and reports ¥60 million in registered capital. Its operations span four business lines: custom factory automation (FA) machinery, ODM/OEM manufacturing for office equipment and medical devices, precision metal parts machining (aluminum, stainless steel, iron, copper, brass at 1/100mm tolerances via 5-axis machining centers), and multi-variety equipment maintenance/modification services.

Core technical competencies are concentrated in paper and film handling, CCD/CIS image sensor control, and precision mechatronics (servo motor control, robotics, welding/joining). Two granted patents anchor proprietary technology: a Spring Auto-Feed Device (Patent No. 6709404, described as globally unique for automating tangled tension-coil spring separation) and a Developer-Type Toner Charge Measurement Device (KYS-001). Self-developed products include the SL1000/SL1000Q screenless digital film scanner (410+ cumulative units, 220+ exported), the SD8800A ScanDIVA A3 face-up book scanner (~270 units supplied to Japan's National Diet Library), the A2 PS7300C book scanner, the PP 4060/PP 4050XP continuous-form LED printers, and the LLP-200 Linen Label Press Machine (launched 2025). ODM/OEM customers include Konica Minolta, Panasonic, Mitsubishi Heavy Industries Mechatronics, SCREEN Holdings, Dynic Corporation, System Gear, Shofu, PSi Laser (Germany), Kodak Alaris (UK), and Covergold (UK). All factories are ISO 9001:2015 certified, Toyokawa holds ISO 14001:2015 and Medical Device Manufacturing Registration (No. 23BZ200280), and the firm has been recognized by METI as a 'Regional Future Leading Company' (2018) and a Certified Health Management Excellent Corporation (2024, 2025).

Revenue is generated through project-based custom FA equipment sales (one-time per machine, with after-sales maintenance), volume ODM/OEM manufacturing contracts, self-developed product sales (direct and via Dynic as master distributor for the LLP-200), and precision machining services sold both to internal FA projects and external customers. The go-to-market is direct enterprise sales-led with dedicated sales personnel at each factory, supplemented by trade show participation (Manufacturing World Tokyo, Kyoto Business Exchange Fair, Mechanical Components Technology Expo, China Suzhou), catalog downloads, and OEM relationships with international partners. The company is privately held with no disclosed external funding, led by President Akihiro Segawa, and announced a management restructuring in June 2026.
