Via tokyohive: Since their debut in Japan last August, KARA's latest single "Jet Coaster Love" has proven to be the most popular as the single has given them their best sales, selling 123,000 copies in it's first week. The high sales volume has also put KARA at the number one spot on Oricon's 4/18 Weekly Single Ranking. This is the first time a foreign female group has had a number one ranking in it's first week of release since the creation of the Oricon Single Ranking back in January 1968, so it has been 43 years and 4 months! "Jet Coaster Love" has sold twice the amount of their previous single "Jumping", which was released during their break-up crisis turmoil last November, selling 55,000 copies in its first week. KARA was selected as the number one newcomer this year and "Jet Coaster Love" is their first number one in both the weekly single and album rankings. Their first single "Mister" and second single "Jumping" both ranked at #5, while their albums "KARA BEST 2007-2010" and "Girl's Talk" both ranked #2. The last time a foreign female artist has placed #1 on the weekly singles ranking was 6 years ago when BoA's "DO THE MOTION" reached #1 on the 4/11 2005 ranking. The last time a foreign female group placed number one, was The Nolans's "Dancing Sister" single on the 11/17 1980 weekly ranking, which became number one in its 16th week; it's been 30 years and 5 months. KARA also left a comment, "Thanks to all of you, "Jet Coaster Love" has become #1. As KARA, we will continue to do our best to cheer everyone up in the future. And, we hope that everything can be restored even just one day sooner". "Jet Coaster Love" is KARA's first single of 2011. It was originally supposed to be released on March 23rd, but was postponed due to the Great Tohoku Earthquake. In order to help out the area affected by the disaster, KARA has decided to donate all proceeds from this single (CD and digitally) to relief efforts.
