Calpis Teams Up with San-X Universe for a Limited-Time Collaboration

A limited-time collaboration between Calpis and San-X Universe kicked off on April 20. The collaboration brings together the beloved Calpis brand and the popular world of San-X characters for a special campaign.

The collaboration video features fan-favorite San-X characters — including Rilakkuma and Sumikko Gurashi — working together to make Calpis while thinking of their loved ones. The video captures the warm, nostalgic feeling that the Calpis brand is known for.
