In 2019, Cité Marine S.A.S. (France), a member of the Nissui Group, became a sponsor of "La Lorientaise," a marathon event aimed at raising awareness of breast cancer. In the marathon, 11,000 women clad in pink T-shirts participated. Participation fees and sponsorship money are donated to a local league for eliminating breast cancer.
Nissui, with the cooperation of its executives and employees, the Nissui Labor Union (NAC) and through the social gathering of maritime employees, donates to the Scholarship Foundation for Orphans from Marine Accidents each year since its foundation in 1970.
In October 2024, Nissui contributed 10 million yen to the United Nations World Food Programme (WFP) as relief funds to support food assistance for those affected by prolonged conflicts and recent disasters.
