Yuko Aoki (青木 裕子, Aoki Yūko?) is a Japanese bikini model who was born on February 5, 1977 in Takahata, Yamagata Prefecture, Japan. She first started modeling in 1995, and became a "Visual Queen of the Year" at Fuji TV for 1996. She was a frequent cover girl on Japanese bikini photo magazines in the late 1990s. She appeared in the advertising campaign for Suntory's Milpower (ミルパワー, mirupawaa?) product.
Aoki stopped modeling in 1998, and "officially" retired from modeling in 2000 and is now focusing on a music career, which was her first interest.
In February 1998, Aoki held a healing music concert at Casals Hall, near Ochanomizu Station. In June 1999, she sought to raise money through her singing for the refugees in Kosovo. On December 16, 2002, Aoki revealed a chocolate covered statute of David Beckham in Tokyo to generate publicity. In 2003 she released an album titled Blue on the Universal Japan label. She is currently the lead vocalist for the band icy blue. She has been the cover model for (and subject of major articles in) nearly fifty issues of various magazines in Japan, including Weekly Playboy's March 12, 1996 issue.
