For member Shimazaki Haruka's graduation, AKB48 official blog has posted the hand-written announcement by Shimazaki Haruka on 3 October 2016.
I, Shimazaki Haruka, announced my graduation from AKB48 during "Baitoru" a new CM press conference today.
Some medias leaked the information, I think it may cause fans worried, and I am relieved I am able to announce it myself today.
My AKB48 activities will be until 31 December 2016. Before that day, I want to try my best to participate activities as an idol. I hope you can keep supporting me.
