It was previously announced that Sashihara Rino�s final performance as an AKB48 member would be on June 20th along with Matsubara Natsumi�s birthday party.

However, after consideration AKB48 Theater manager Togasaki Tomonobu posted on his Google+ account that Sashihara�s final performance would be postponed until sometime in July.

Togasaki explains, �The reason for this is it is not possible to hold both Sashihara�s last performance and Matsubara�s birthday performance by simply opening at 18:30 and adding 30 minutes to the scheduled performance.�

Many fans sent Togasaki tweets expressing their concern for both Sashihara and Matsubara, since it wasn�t fair that Sashihara�s final performance would be during Matsubara�s birthday party and could make it uncomfortable for both parties.

Togasaki continued, �In order to make sure that Sashihara gets a proper performance to send her off to HKT48, we will readjust the schedule and announce it to the fans� The 20th will be Matsubara�s birthday performance. I hope you will all join us in the celebration.�
