Seiko

What Seiko does

Seiko Co., Ltd. (靜甲株式会社, TSE Standard Market: 6286) is a Shizuoka, Japan-based diversified industrial conglomerate founded in 1939, operating across four primary business segments: custom packaging machinery, cold forging parts, a trading division distributing industrial equipment, and a market development division for energy and automation solutions. The company designs and manufactures made-to-order automatic filling and packaging machinery for food, pharmaceutical, cosmetics, and chemical manufacturers, including the award-winning Neck Transfer BTW filler that handles bottles by neck rather than body to eliminate changeover parts. Its cold forging division produces 1,500+ precision component types for automotive and industrial customers at the ISO9001/ISO14001-certified Fujikawa Factory. The trading division operates as an authorized dealer for Mitsubishi Electric (since 1952), Sumitomo Rubber, Kawasaki Heavy Industries, and Kurashiki Kako, distributing FA systems, electrical equipment, air conditioning, elevators, and tires across Shizuoka Prefecture and surrounding regions. The group also owns automotive dealerships through wholly-owned subsidiaries for Subaru, Volvo, Porsche, and BYD EVs, plus a vehicle rental business and staffing services. Consolidated revenue for FY March 2026 was ¥448 billion across 892 employees, with 9 consolidated subsidiaries spanning manufacturing, trading, automotive retail, and services. The company's go-to-market combines direct enterprise sales for custom machinery, a wholly-owned distribution subsidiary (Nippon Kikai Shoji) for packaging equipment, and authorized dealer relationships for industrial brands, with an emerging presence in EV infrastructure through its BYD partnership and proprietary microgrid energy systems.
