Popular Korean girl group KARA held a surprise stage performance in front of the popular department store, Shibuya109 in Tokyo earlier today to celebrate their debut in Japan.

KARA performed their debut song titled "Mister" in front of more than 3000 fans. Because this was a "surprise," many people came as the word spread quickly creating a ruckus in the crowded district of Shibuya. At this event KARA was scheduled to take photos with fans, have a brief Q&A session, and perform some songs. However, because the fans were over reacting and created a panic, they had to unfortunately cancel this surprise event after performing just one song.

KARA will hold a hand-shake event in Shinkiba Stadium Coast on August 14th.
