The Japanese professional baseball team, Seibu Lions, recently incorporated popular Arashi songs into their practice. The intention was to keep the spirits high and induce a positive and energetic environment during training sessions. Fans have applauded this move as it uniquely blends pop culture with sports and seems to have positively influenced the team's performance.

In Japan, baseball is considered more than just a sport. It’s a significant aspect of the culture, and teams often employ various methods to maintain team morale, enliven the atmosphere, and draw in crowds. Using pop songs - especially those by renowned bands like Arashi - is one such method that appeals to fans who support both the team and the band.

Similar to how some US and EU teams use certain popular songs during their practice sessions or as their “walk-up” songs, the Seibu Lions' use of Arashi’s music is a tactic employed to boost team morale and fandom. The main difference lies in the cultural backdrop and the popularity of the songs chosen.
