Our group has established a "Social Contribution Policy" in our Sustainability Basic Policy, and as a good corporate citizen, we engage in a variety of activities that contribute to the future of society.
The Niterra Group has been conducting tree-planting since 2022. Our group employees have participated in this activity to deepen understanding that forests not only absorb carbon dioxide and reduce global warming, but also play an important role in preserving biodiversity by providing a home for a wide variety of living creatures.

Volunteer Activity (Photographed in 2025)Our Group is working to nurture human resources for the next generation at our locations around the world. We are engaged in initiatives such as hosting company visits for students, conducting visiting classes at schools, fostering interest in science through workshops, and supporting idea contests in which students participate. In addition, as employment support for young people, we promote ongoing assistance tailored to local needs and generations, including holding technical training sessions and seminars on life planning.
In order to develop human resources who will play a key role in international exchange and friendship, our charitable trust, the Niterra scholarship fund for overseas students, provides scholarships to international students from all over the world. It was established in 2007 as the "NGK Spark Plug Asian Student Scholarship Fund," and in 2016, the 80th anniversary of its founding, it was renamed to its current name, which covers students from all over the world. In FY2025, scholarships were awarded to 12 international students attending universities and graduate schools in Aichi Prefecture.
