To commemorate the renewal of Umi kara Sarada Flake packaging to a format that does not use plastic trays, Nissui conducted the “Umi kara! Sma-Eco Campaign" from June 1 to August 31, 2025. Through this campaign, Nissui donated 10 yen to The Nature Conservation Society of Japan (a public interest incorporated foundation) for each entry received. The total donation amounted to 442,810 yen. The donated funds will be used for nature conservation activities conducted by The Nature Conservation Society of Japan.
*This campaign has now ended.
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 officers 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.
