Initiatives to Support a "Daily Life of Continued Movement"

Under the mission of "continuously responding to 'how I want to be'," Wellvenus has been working to "improve the quality of daily life" for its customers through its products.

In particular, responding to the desire to "continue walking on my own feet" and "continue going to the places I love" is one of our key themes.

Through our sponsorship with the Hokkaido Nippon-Ham Fighters, who share our roots in Hokkaido and engage in community-based activities, we will deliver the value of a "daily life of continued movement" to even more people.

About the Provision Initiative for Volunteer Staff

As part of this sponsorship, we have begun providing "Kitaguni no Megumi" to the volunteer staff who work at ES CON FIELD HOKKAIDO, the team's home stadium.

This initiative is a support measure focused on the physical burden of working in a real-world environment like a stadium. We aim to support those who use their bodies daily, such as by moving around the vast stadium or climbing stairs, and to create opportunities for them to experience the value of a "daily life where you can continue to move energetically."

Future Outlook

Wellvenus will continue to deliver healthy daily lives to more people while sharing the experiences and feedback gained through these initiatives.
