Professional Baseball

The Saitama Seibu Lions have won the league championship 23 times, the most of any team in the Pacific League, and have won the Japan Series 13 times. In the 2020 season, they hope to win their third league championship in a row and the Japan Series. A large-scale food area, indoor amusement facility, new goods shops, and more will also be opened in the 2020 season. Some seating in the MetLife Dome will be renovated, including the area behind the backstop and infield reserved seats. The spectating environment will be greatly improved for even more enjoyable services.
Moreover, the 2020 season marks the 70th year since the team name was changed to the Lions. Various events are planned in which past players will be featured. We hope you’ll keep showing your enthusiastic support for the Saitama Seibu Lions in the 2020 season!
