KARA's ventures in Japan have been nothing short of a complete success this year. They've grabbed various top spots on the Japanese ranking chart, Recochoku, for their singles and music videos - even securing #1 for the "New Artist" category. The girls have done it again with their free music app, "KARA Jumping", as it pulled them in the #1 spot for the 'free music category' on Japan's iTunes App store chart. The application was first revealed on December 4th without any official promotions, and earned 50,000 downloads within 10 days of its release through 'word-of-mouth' by iPhone users. Many positive reviews have been made for the app, with Japanese downloaders commenting, "It's a high quality application that makes it hard to believe that it's free. I am truly enjoying this," and "It's great to be able to see high quality videos of KARA through apps." Despite there being a Korean version of the application, 90% of the app's worldwide downloads come from Japan. A representative of production company Danal commented, "KARA's popularity in Japan exceeds anything imaginable." Source: Newsen via Nate
