Japan Automatic Machine

What Japan Automatic Machine does

Japan Automatic Machine Co., Ltd. (J.A.M.) is a privately-held Japanese precision manufacturing company founded in 1932 as Mizuno Seisakusho and renamed in 1968. Headquartered in Tokyo with manufacturing operations in Yokohama, Haramachi, Iwaki (Japan), and Huizhou (China), J.A.M. operates three integrated product divisions: connectors (automotive, board-to-wire, wire-to-wire, high-frequency, FFC/FPC), wire processing machines (fully automatic and semi-automatic crimping machines, applicators), and precision machinery (servo presses, hydraulic presses, precision vises, chamfering machines). The company develops Japan's first domestic fully automatic crimping machine in the late 1970s and holds proprietary servo press and precision vise technologies with documented metrics including 0.005mm vise repeatability and 4.9kN to 490kN press capacity range.

The company's business model centers on direct hardware sales organized by product division, complemented by a global distribution network including Digi-Key Electronics and 12+ regional channel partners across Asia, Europe, and the Americas. Precision vises, presses, and chamfering machines are sold through machine tool trading companies, while connectors and crimping machines use direct sales plus distributors. Revenue streams include capital equipment (crimping machines, presses), consumables (applicators), components (connectors, terminals), and after-sales parts and service. The primary customer segments are automotive (IATF 16949-certified at Tanshi 2022 and Iwaki 2024 plants) and electronics manufacturing, with secondary exposure to mold/die and wire harness industries.

J.A.M. operates a vertically integrated model spanning mold design, ultra-precision processing, and mechatronic integration. Recent strategic moves include the 2022 acquisition of Kyowa Fine Tool (terminal die design), the 2023 Sendai R&D Center opening, a 2025 IoT-enabled crimping machine co-developed with B-EN-G, and ongoing product launches (coaxial cable processor in 2026, CN308 for board industry). The company is led by President Masafumi Mizuno of the founding family, with no external equity investors and a stable subsidiary structure spanning Singapore (regional HQ), Thailand, China, Hong Kong, USA, Switzerland, India, Malaysia, Philippines, and Vietnam.
