NEC has served as the sponsor for the Wheelchair Tennis Tour organized by the International Tennis Federation for over 20 years in order to promote sports for those with disabilities.

Beginning in 2015, the Tokyo Metropolitan Government organizes an industry-government-academia collaboration event, TOKYO Mimi College (called "TOKYO Sign Language College" in 2015), with the aim of deepening understanding and interest in hearing impairment.
Since its start, NEC has co-hosted this event with Tokyo Metropolitan University.

Collaboration with the Tokyo Para-Sports Association began in 2016.

In 2019, NEC signed a comprehensive partnership agreement with the Tokyo Voluntary Action Center, which plays a central role in promoting volunteerism in Tokyo, in order to foster a volunteer culture, create volunteer legacies and promote the building of an inclusive society by leveraging the strengths of the two organizations.
