Lady Gaga designed a 'We Pray For Japan' wristband, which sells for US$5 at her official website's online shop. All benefits go to relief aid in Japan.
South Korean television and pop stars, who are very popular in Japan, have donated millions of won to the quake and tsunami victims. Kim Hyun-joong, a member of the popular South Korean boy band SS501, and actors Ryu Si-won and Song Seung Hun have also made donations.
