Next-Generation Mobility
Connected by Ceramics

We leverage the characteristics of ceramics, such as spark plugs and sensors, taking great pride in our global top market share,
to create an environmentally friendly mobility society that enriches people's lives.

Plugs

Plugs

Our spark plug was the first to be made in Japan. We now enjoy the top market share in the world. Spark plugs play a crucial role in starting the engine; cars simply cannot run without spark plugs. Our proprietary ceramics technology delivers performance to withstand harsh environments inside the engine and improve fuel efficiency. By improving fuel efficiency, these spark plugs also contribute to environmental conservation by reducing CO₂ emissions.

Sensors

Sensors

Sensors are core automobile components capable of sensing vibrations and exhaust gases to ensure safe, efficient engine operation. They help to detect engine abnormalities, make exhaust gas cleaner, and improve fuel efficiency. Our proprietary technology achieves fast and accurate sensing even in the harsh environments inside vehicles, enabling us to meet increasingly stringent exhaust gas emission regulations in recent years.
