Mero Narita, who helped deliver the athletes' oath for the World Games 11 days ago, delivered a gold medal Sunday -- the final day of competition -- when she won the women's wakeboard event in water skiing.
Tokyo lifeguard Masami Yusa then made it a mini-gold rush for the host country by winning the women's beach flags event in the life saving competition, which brought Japan's gold medal total to nine.
Japan also struck gold in the demonstration sport of sumo, winning four of the eight gold medals on offer at Tenno Municipal Gymnasium.
Russia topped the final medal standings with 24 gold medals and 44 overall (24-15-5), followed by the United States with 31 (15-8-8) and France with 23 (12-5-6). Japan was seventh with nine gold medals and 25 overall (9-6-10). At Ogata Water Ski Course, Narita ignored the pain of a shoulder separation suffered in July to turn in an energetic routine for 44.30 points and the gold medal ahead of Australia's Leza Bugden and compatriot Kiyomi Suzuki.
