On the 5th, Seibu Lions announced that their slogan for this season has been decided as "Break Through." At a press conference held at the team's office in Tokorozawa City, Saitama Prefecture, manager Fumiya Nishiguchi (53) explained the meaning behind the slogan, saying, "You can't win if you don't hit. It embodies the meaning of hitting and hitting and aiming for the top."

Last season, the team struggled with a poor offense, finishing 5th with the league's lowest team batting average of .232. Facing the slogan, which he himself suggested, the manager expressed his hopes for the fielders to step up, saying, "We've been promoting a style of baseball that wins through defense, but you can't win by just defending. I think we have the foundation for winning through defense, so now hitting is crucial. I want them to hit, hit, and win through hitting." Looking ahead to the season, with aggressive reinforcements including Ishii and fielder who have moved after exercising their free agency rights, and aiming for their first league championship in seven years and their first Japan Series title in 18 years, he declared, "If we're going to do it, we're going to aim high. We're aiming for the championship, so we want to work together as a team and do our best."
