Niterra Co., Ltd. (⽇本特殊陶業株式会社, Nippon Tokushu Tōgyō kabushiki gaisha, lit. 'Japan Special Ceramics' or 'Japanese Special Ceramics') is a public company established in 1936 and based in Nagoya, Japan. Formerly known as NGK Spark Plug Co. Ltd., the company’s automotive business (with its brands NGK Ignition Parts and NTK Vehicle Electronics) revolves around the manufacturing and the sale of spark plugs and related products for internal combustion engines, as well as vehicle electronics and ceramics for a wide range of applications in the automotive industry and beyond.

Niterra is a coined word, which combines the Latin words ‘niteo’ meaning ‘shine’ and ‘terra/earth’.^[1] It expresses the Group’s desire to be a company that not only contributes to a sustainable society, but also one that makes the earth shine: a goal formulated in its 2040 Vision.^[2]

As of April 2024, the company employs around 15,900 people and the company’s automotive and technical ceramics activities generate a total annual turnover of around 4.45 billion euros worldwide. It operates a network of 61 consolidated subsidiaries, 24 manufacturing and sales organisations, four Technical Centres and three Venture Labs worldwide.^[3] In 2021, Niterra moved its global headquarters to the N-Forest Building located at its Komaki Plant in Japan.^[4]
