Japan rallied from a set down to beat Russia 3-1 Sunday in the World Grand Prix women's volleyball tournament.

Japan improved its record to 3-3 with a 20-25, 25-19, 25-15, 25-21 win at Osaka Municipal Gymnasium. Russia fell to 3-3.

After dropping the first set, the host went on a fierce blitz with the addition of 21-year-old Maiko Kano, who penetrated the Russian defense with back row spikes.

The Japanese women also did well in serving and blocking.

"The blocks that we have been going over in practice worked the best yet in this tournament today," said Japan coach Masayoshi Manabe. "We want to continue with this same level of intensity."

In the day's other Pool F match in Osaka, South Korea (1-5) defeated Puerto Rico (1-5) 25-18, 25-18, 24-26, 22-25, 15-13
