The Yomiuri Giants, Yakult Swallows, and Yokohama Bay Stars worked together on something called Get Stamp → DeKA Badge! last year. The three teams will be getting together again this year and the first installment will take place during a Yomiuri-Yakult series at Jingu Stadium between April 26 and 28.
Special events currently scheduled for the series:
- Fans pick the MFP (Most Feared Player)
- Tickets that include cheer umbrellas
- Events for fans of the visiting team
- Mascots, cheer-leaders, and stadium DJs from both teams will make appearances at the game
