  2. NGK Spark Plugs

    1937The first domestically produced
    NGK Spark Plugs Begin Production

    A spark plug developed by refining the technology cultivated in the ceramics industry.
    In internal combustion engines, it acts as a "lighter," electrically igniting the air-fuel mixture.
    Through the high quality of its products, it helped ignite the motorization of Japan, went on to drive the global automotive industry, and ultimately secured the top market share in the world.*
    ​​​

    *Our estimate as of the end of March 2025

    A business brand whose spark plugs have been widely loved and trusted for many years since the establishment of the company. It has now grown into a world-leading brand, serving as our flagship product line and contributing significantly to the development of the automotive industry.

  5. NTK brand electrostatic chucks

    1989Sales of electrostatic chucks started. 

    Supporting the evolution of the digital society through ceramics.
    An electrostatic chuck is a device that utilizes the property of static electricity to attract and secure silicon wafers during the semiconductor manufacturing process.
    Featuring complex heater-electrode configurations and flexible component placement, these chucks enable uniform control of silicon wafer surface temperatures, thereby enhancing both the efficiency and quality of semiconductor production.
    Currently manufactured and sold by NTK CERATEC CO., LTD. (headquartered in Sendai City, Miyagi Prefecture).

  8. Niterra Tool company building entrance

    2025Acquired all shares of Toshiba Materials Co., Ltd.; renamed the company Niterra Materials Co., Ltd.
    ​

    Leveraging the superior wear resistance and strength of silicon nitride, the company manufactures and sells products such as bearing balls and heat-dissipating substrates. These components contribute to enhanced performance in a wide range of machinery, including electric vehicles (EVs).
    ​

    Bearing balls

    These products perform rolling motions inside bearings, reducing friction and ensuring smooth rotation. Their high wear resistance contributes to a longer service life.
