Spark plugs

Spark 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.

Balls for bearings

Balls for bearings

These bearing balls are used in machine tool parts and inverter motors. They are made of lightweight, high-strength silicon nitride material and are smooth with low friction so that they can be used with a small amount of lubricant. The trend toward higher-performance inverters and motors rotating at higher speeds expands their use in EV and semiconductor manufacturing equipment applications.

Reversible SOC System

Reversible SOC System

We are currently working on the development of a "reversible SOC system" that utilizes the fuel cell technology we have developed over the years. This system produces hydrogen through water electrolysis and generates electricity through fuel cells, all in a single cell stack. The development of this system will make it possible to address the social issue of increasing surplus electricity with the increase in the ratio of renewable energy, and is expected to contribute to the realization of a decarbonized, hydrogen-circulating society.

SUISO no MORI Project

SUISO no MORI Project

The Earth's warming due to the increase in greenhouse gases, rising sea levels, and the increasing intensity of natural disasters are becoming more severe environmental issues. Properly managing and reducing these effects has become a common agenda for humanity, and hydrogen is attracting attention as an alternative energy source to replace fossil fuels. The SUISO no MORI (Hydrogen Forest) Project is a framework aimed at accelerating the realization of a hydrogen and circular-carbon society by supporting related technologies. Through fund investments, provision of demonstration facilities, and incubation programs, we help startups turn their ideas into reality.

Regional CCU™

Regional CCU™

The idea is to capture CO₂ emitted from factories and use it as a resource, making use of current industry and creating a sustainable city. By optimally managing CO₂ emissions, demand, and renewable energy electricity production based on CCU※ (Technology to capture and utilize CO₂), CO₂, hydrogen, synthetic fuel, and electricity can be interchanged and circulated locally. We will contribute to the realization of a carbon-neutral society that takes advantage of regional characteristics.
