On the 17th, Lotte announced that they had cooperated with the "Summer Accident Zero Campaign: Public-Private Joint Street Awareness Activity" hosted by the Chiba Coast Guard and the Chiba Prefectural Police Headquarters, which was held on the same day at the plaza in front of the west exit of Keisei Chiba Station. The team mascot, Ma-kun, and MIKU from the team's official cheer performer group M☆Splash!! participated in awareness activities aimed at preventing accidents near water.

The event was held with the aim of preventing the increase in maritime and water-related accidents during the summer months. At the venue, five points were introduced to prevent accidents during leisure activities such as swimming and fishing at the beach or river: "Wear a life jacket," "Do not enter restricted areas," "Consider the weather forecast and your physical condition and do not overexert yourself," "Play at beaches with lifeguards," and "Keep an eye on your children."

Ma-kun and MIKU, who participated in the opening ceremony, urged attendees to enjoy themselves safely by the water. During the event, they also announced the "2026 SUMMER ENJOY Special Invitation," with the aim of allowing many people to enjoy watching professional baseball during the summer holidays.

"Summer vacation is full of fun events, but safety is the most important thing! Let's all follow the rules, like wearing life jackets and staying away from dangerous places, so we can have a fun summer vacation! A fun summer vacation is only possible if it's safe! Come and play at Zozo Marine Stadium full of energy!"

▼ MIKU's comment

"Summer is a season when we have more opportunities to spend time by the water, such as at the beach or river. Through this activity, I was reminded that it is important for each individual to be mindful of safety in order to prevent accidents. In order to create fun summer memories, I hope you will follow the rules and enjoy yourselves safely by the water!"
