Nippon Seiki

Founded in 1946 in Nagaoka, Japan, Nippon Seiki Co., Ltd. quickly established a reputation for excellence in motorcycle speedometer production before expanding into the automotive sector. The company specializes in planning, designing, developing, manufacturing, and selling electronic devices and mechatronics products, particularly instrument clusters for automobiles and motorcycles worldwide. Their product portfolio includes automotive clusters, peripheral systems, gauges, head-up display units that project vehicle information onto windshields, and various sensors including level, revolution, pressure, angle, and temperature sensors. In the 1980s, as the Japanese automotive industry gained global recognition, Nippon Seiki strategically expanded into the Americas, with NSNA now serving as their North American Operations and Technical Design Center. In 1995, the company established Defi as their aftermarket brand to bring cutting-edge technologies to the aftermarket sector. Today, Nippon Seiki has evolved from its origins in motorcycle speedometers to become a global leader in automotive instrumentation, gauges, sensors, and display technologies, serving major automotive manufacturers worldwide while maintaining its headquarters in Nagaoka and operations across multiple continents.
