Effective April 1, 2023, our English company name has changed to "Niterra Co., Ltd." As a result, NGK SPARK PLUG Group has become the "Niterra Group".
Niterra is a word that we have coined that combines "niteo," which means "shine" in Latin, and "terra," which means "earth." It expresses the Group's determination to not only contribute to a sustainable society, but also brightens the entire global environment.
