On the 2nd, Nippon-Ham announced that they had reached an agreement with outfielder Haruki Nishikawa, who had been released from Yakult Swallows, to join the team.

On his return to his old stomping grounds, where he played from 2011 to 2009, Nishikawa said via the team, "When I was told that I was out of the lineup from The Swallows, I thought that if I was going to play baseball for the last time, I would only play The Fighters. The Fighters If I couldn't play for baseball, I would quit .... I am happy to be able to play baseball once again wearing the The Fighters uniform. With the increase in the number of young players, I think that many fans know the names of the young players. I will do my best to make sure those fans remember my name and those who have been with the team since I was a member will remember me.
