To mark the 1st anniversary of the Great Eastern Japan Earthquake (東北地方太平洋沖地震;동일본 대지진), the members of T-ara have decided to donate all of their royalties from their Japanese version of “Roly Poly” single to support those affected by the Fukushima Daiichi Nuclear Catastrophe (福島第一原子力発電所事故/후쿠시마 제1 원자력 발전소 사고)
T-ara debut Japanese single, “Bo Peep Bo Peep” grab the No.1 spot on the Oricon Daily Music Chart, which is the first for a Korean girl-group. T-ara thought of all the painful losses of the victims of the nuclear disasters of Fukushima, who have suffered from the triple disaster a year ago. They wanted to repay the Japanese fans for their love and support. T-ara’s Japanese agency promised to help convey T-ARA’s feelings behind their donation. T-ara stated that although their donation can’t erase the trauma of the victims, they hope that it could still reach out to them.
