Japan's five-time world champion Kaori Icho retained her Olympic women's wrestling 63kg title while up-and-coming Wang Jiao kept the 72kg title for China at the Beijing Games Sunday.
The 24-year-old Icho, whose older sister Chiharu grabbed her second straight 48kg silver medal on Saturday, beat European champion Alena Kartashova of Russia in the final by taking the two periods 1-0 each.
The 63kg bronze medals went to Kazakhstan's Yelena Shalygina and Randi Miller of the United States.
Wang, 20, the world junior champion, pinned reigning world senior champion Stanka Zlateva of Bulgaria for a fall in the 72kg final.
The heavyweight title was won by compatriot Wang Xu at the Athens Games four years ago when women's wrestling made its Olympic debut.
The bronze medals went to Japan's Kyoko Hamaguchi and Agnieszka Wieszczek of Poland.
Japan dominated the four-category contest with the same wrestlers winning the same medals as they did in Athens, two golds, one silver and one bronze.
China and Canada won the two other gold medals.
Icho, 24, narrowly beat Canada's Martine Dugrenier in the semi-finals after overwhelming her two earlier opponents by a fall.
Wang crushed Zlateva's dreams of adding an Olympic title to the world gold medals she won in 2006 and 2007 and three European titles from 2006 to 2008.
In the semi-finals, Wang also swept aside Hamaguchi by a fall, avenging the 0-2 loss she suffered at the hands of the Japanese in the 2005 world semi-finals.
