=====

This is Ogino Risa of Kenkyusei.

Thank you always for all of your support.

I have an announcement to make to everybody.

I, Ogino Risa, have decided to stop my SKE48 activities temporarily starting in December.

My 5-year-old sister recently entered the hospital, so I have decided that it's the time to stick together with my�family, and look after her.

After the discussion with staff members, I chose to stop my activity for a while.

I'm very sorry to my fans who always cheer for me, and to members who always support me.

For now, I want to put my all into looking after my sister with my family, so that I can come back and perform in front of you again, when my sister's condition and my family situation are settled down.

Please continue to support me.

According to SKE48's management secretariat�blog, they have accepted Ogino's request to suspend her activities until the end of April.
