Seibu Lions announced that they will be holding "LIONS GOLF EXPERIENCE STADIUM 9," where people can enjoy a driving range experience, at Belluna Dome on February 11, 13, 14, and 15, 2026, and a new event, "LIONS STADIUM 9 BELLUNA DOME CUP," on the 21st and 22nd, where players will compete for scores by taking approach shots from the stands.

The "LIONS STADIUM 9 BELLUNA DOME CUP," scheduled for the 21st and 22nd, is a competition where players aim for the green on the field from nine teeing areas within the ground. Three The Lions alumni, including Hironori Ishige, will appear each day, and former Japanese women's wrestling representative Saori Yoshida is scheduled to make a guest appearance on the 21st.

Also, following last year's success, a fan meeting where fans can interact with The Lions alumni will be held on the 11th, 14th, and 15th. Attendees can enjoy talk shows, photo sessions, and autograph sessions featuring players such as Hironori Ishige and Hatsuhiko Tsuji.
