On the 3rd, Lotte announced that they will hold a regional revitalization event called "ALL FOR CHIBA" during their games against Rakuten Eagles at Zozo Marine Stadium from September 8th to 10th.

"ALL FOR CHIBA" is a regional collaboration event that showcases the charms of Chiba Prefecture. It will feature sales of Chiba's gourmet food and local products, regional PR, various free events, and appearances by local mascots from Chiba Prefecture.

Additionally, before the game on September 9th, with the cooperation of Cheer & Dance Education (USA Japan), Chiba Lotte Marines are recruiting dance clubs, cheerleading clubs, and other student groups from junior and senior high schools in Chiba Prefecture to perform a dance routine alongside the team's official cheer performers, "M☆Splash!!". Applications are accepted on a school-by-school basis, with a maximum of 500 participants.

On the day of the event, starting around 5:30 PM before the match, they will perform a special dance performance with M☆Splash!! for approximately 5 minutes (the song will be decided at a later date).

Furthermore, a performance set to Kishidan's "One Night Carnival" is scheduled after the bottom of the 5th inning. Details about the event and how to apply can be found on the team's official website.
