日本バスケットボールリーグ
In 2005, the number of professional sports teams based in Sendai suddenly increased to three. The Tohoku Rakuten Golden Eagles was introduced as a new Pacific League baseball franchise after widely publicized turmoil involving the merger of the Kintetsu Buffaloes and the Orix Blue Wave developed into the first strike in Nippon Professional Baseball. Additionally, the Japan Basketball League, which began its inaugural season in November 2005, included the Sendai 89ers among its first six teams.
