Najico Spicer Co., Ltd.

Najico Spicer Co., Ltd., established on May 8, 1975, is a prominent global supplier of essential automotive and industrial components, operating as a joint venture between Dana Incorporated (a US-based global leader in drivetrain and e-propulsion systems) and Najico Co., Ltd. Headquartered in Ginza, Tokyo, the company has built a steadfast reputation over the decades by merging Dana’s world-class engineering capabilities with Najico’s extensive domestic network and deep understanding of the Japanese market.

The core of Najico Spicer’s business lies in the import, export, development, and manufacturing of drivetrain, sealing, and thermal-management products. The company primarily serves three major categories: commercial vehicles, off-highway machinery (such as construction, agricultural, and specialized vehicles), and other Dana-brand products. In particular, the renowned "Spicer®" brand components, including heavy-duty propeller shafts and axles, play a critical role in ensuring the safety, reliability, and performance of trucks, buses, and earthmoving equipment operating under demanding conditions.

Beyond its functions as a trading company, Najico Spicer also possesses robust manufacturing capabilities. Since its inception, the company has utilized Dana’s patented nylon coating technology to produce specialized components domestically. This hybrid business model—acting as both an importer of global standard parts and a domestic manufacturer adapting to specific customer needs—gives Najico Spicer a unique competitive edge.

As the automotive industry undergoes a once-in-a-century transformation toward electrification, Najico Spicer is aggressively expanding its portfolio to include advanced e-Mobility solutions. Drawing upon decades of expertise in power transmission and thermal management, the company is supplying innovative electrification products to support the global shift toward zero-emission transportation.

Committed to sustainability and continuous innovation, Najico Spicer remains a vital partner for the automotive and heavy machinery industries worldwide, driving the future of a sustainable mobility society.
