BANSHUN INC.

What BANSHUN INC. does

TB Banshu Electric Equipment Co., Ltd. (TB播州電装株式会社), operating as BANSHUN INC., is a Japanese manufacturer of wire harnesses and related electrical components incorporated in 1968, with operational roots dating to 1965. The company designs and manufactures wiring harnesses for two primary end markets: motorcycles and construction machinery, with a secondary line of special-vehicle harnesses used in outboard motors, agricultural equipment, cranes, and forklifts. In motorcycles, its Indonesian-built harnesses are used in approximately 40% of motorcycles sold across Indonesia, and in construction machinery it supplies major Japanese OEMs including Kobelco, Komatsu, Kawasaki Heavy Industries, Kobe Steel, and Mitsubishi Electric with main, battery, engine, cab, camera, and pump harnesses.

The company operates a vertically integrated, multi-country manufacturing platform comprising wholly-owned subsidiaries: PT. BANSHU ELECTRIC INDONESIA (BEI, est. 1996) for harness assembly, plus adjacent plastic molding (PT. BANSHU PLASTIC INDONESIA, 2002), thin-plate metal stamping (PT. BANSHU METAL INDONESIA, 2003), and rubber molding (PT. BANSHU RUBBER INDONESIA, 2004), with Elcon Banshu Wiring System Pvt. Ltd (EBWS, 2019) extending the model into India. As of April 2024 the group employed 223 people. Production is coordinated between Japanese headquarters and Indonesian factories through a proprietary WEB-EDI system for production planning and shipping, with BMW CAD supporting harness layout design and IT-based traceability extending to the individual wire level. The company holds ISO 9001 (2007) and ISO 14001 (2009) certifications, and BEI's Subang factory received AEO (Authorized Economic Operator) certification in 2017.

The business model is B2B contract manufacturing with quote-based pricing negotiated through a nine-step service flow from inquiry and analysis through prototyping, witnessing, production, inspection, shipping, and after-sales. Revenue is generated through hardware sales of wire harnesses and import/export of related electrical components. The company became a subsidiary of Tokyo Boeki Holdings Corporation through a capital alliance in April 2023, coinciding with its rebranding to TB Banshu Electric Equipment Co., Ltd., and is currently expanding via a new India Noida factory (production start February 2026) and a Tokyo Sales Office opened in April 2025.
