Seibu Lions On December 4, Teruki Koga infielder (25) will be sent to the Japan Winter League 2025, which is being held at Koza Shinkin Stadium in Okinawa from November 22. He will start participating on December 6. Teru Koga said through the baseball team, "Although I will be participating in the middle of the tournament, I would like to expand my playing range while actively challenging myself in various things. This is a valuable opportunity to see, hear, and learn about the plays and ideas of players from other teams up close, so I want to use what I gain from this experience for my own growth. In particular, I will work hard on my batting so that I can come back as improved as possible.

Three players from Seibu Lions have already participated: pitcher Haruse Narita (19), pitcher Sinclair (24), and outfielder Ramal (19).
