Kaima Taira Set for MLB Move After Seibu Lions Agree to Posting System
Pitcher Kaima Taira will move to MLB after the Seibu Lions agreed to post him. He holds a 1.36 ERA this season.

The Move to Major League Baseball
The Seibu Lions have announced that right handed pitcher Kaima Taira will be allowed to pursue a career in Major League Baseball. The Japanese club plans to use the posting system, which enables players to sign with teams abroad.
Taira is 26 years old and comes off a dominant campaign in Japan. He posted a 12-5 record this season along with an ERA of 1.36. In 2025, he also recorded 31 saves for the Lions. Over his full career in Japan, he has built a 37-24 record.
High Ambitions for the Pitcher
Taira has high expectations for his future in the majors. He is focused on winning major individual awards and playing on the biggest stage in the sport.
"As a pitcher, my goal is to win a Cy Young award," Taira said, as quoted by Japanese news agency Kyodo. He added, "And I'd like to pitch in the World Series as well."
Japanese Stars in the Majors
Japanese players have made a massive impact across American baseball over the past three decades. Former star Ichiro Suzuki was elected to the Hall of Fame.
More recently, Shohei Ohtani and Yoshinobu Yamamoto led the Los Angeles Dodgers to victory. In 2025, they helped Los Angeles become Major League Baseball's first repeat World Series champion in twenty five years. Ohtani earned his fourth MVP award, while Yamamoto was named World Series MVP.
More Talent Coming from Japan
Taira is not the only high profile player eyeing a move abroad. Japanese hitter Teruaki Sato recently announced that he also wants to move to American baseball.
Sato had a huge year in Japan, hitting 39 home runs with 106 RBI this season. With Taira and Sato preparing for moves, teams in the majors will be watching closely as more talent comes across the ocean.
