Girl group KARA has thrown away their cute image and has revealed their new sexy concept in Japan.

On August 28, Japan media stated, "KARA has returned to Japan as a new 4 member group and has held their first official event here, showing their upgraded style."

At this event, the members were wearing white outfits that showed a bit of midriff. They performed their hit song, "Mister" and revealed a more grown up performance. 

They also performed three new songs including, "Step", "So Good" and "Mamma Mia."

The members stated that they were honestly very nervous at first, but after receiving all the support from fans, they were reassured.

On the other hand, they will begin their Japan arena tour this October.
