On April 6th, girl group KARA unleashed their third Japanese single, "Jet Coaster Love", after the original release date was pushed back due to the natural disasters that struck Japan early last month. As soon as it was released onto the music charts, "Jet Coaster Love" instantly rose to #2 on the Oricon Chart. The incredible thing was that KARA dominated the chart without the help of promotional activities,�thus proving once again their explosive popularity in the country. All proceeds from the single will be donated to Japan's natural disaster relief aid. Source + Photo: Star News
