At the ceremony, JNA recognized individuals who either helped improve the skills of nailists or developed the nail art industry. Koda Kumi, Ayumi Hamasaki and Becky are bestowed the honor of 'Nail Queens', and received special testimonial awards. Koda Kumi attended the ceremony, and also represented Ayu and Becky (who could not attend due to their busy schedules).
For the event, the singer sported some unique bejewelled nails, and posed for various photos with her unique hand-shaped trophy.

This is not the first time for any of them to receive recognition for their nails. Every year at the International Nail Expo in Tokyo (being held on November 28-29 this year), several "Nail Queen" awards are handed out. Koda, Hamasaki, and Becky have each won three times, placing them in the "Hall of Fame" and making them ineligible for future awards.
Incidentally, the 2010 Nail Queen winners have already been revealed. Kyōko Fukada (深田恭子; born November 2, 1982, in Tokyo, Japan) is receiving her third award in the actress category, becoming the fourth person to join the "Hall of Fame." The others are Suzanne (24) in the talento category, Marie (23) in the artist category, professional tennis player Ai Sugiyama (杉山愛; born July 5, 1975 in Yokohama, Japan) in the sports category, Junpei Mizobata (溝端淳平; born June 14, 1989) in the men's category, and Uno Kanda (神田うの; born March 28, 1975) in the special award category.
