In 2004, the Japanese Pacific League, amidst financial difficulties, dropped two teams, leading to a player strike. Mikitani was approached by league officials about putting together an expansion team in Sendai, which would be named the Tohoku Rakuten Golden Eagles. Mikitani rebuilt, restored and renovated the stadium in Sendai, prior to the team's inaugural season in 2005. The Golden Eagles won the 2013 Japan Series, two years after the 2011 earthquake and tsunami that devastated Sendai and the Tōhoku region.
