The U.S. won the tournament in 2002 and 2008. The team will be looking to emulate its USA senior national team, which won its third straight gold medal at the London Olympics by beating Japan in the final.
Host nation Japan is aiming to add to the success of the 2011 World Cup win by its senior women's team.
Uzbekistan was originally scheduled to host the Aug. 19-Sept. 8 tournament, but FIFA stripped it of hosting rights because of ''a number of logistical and technical issues.''
The Americans will be motivated given they failed to finish among the top four at the 2010 U-20 tournament in Germany, where they suffered a surprising exit to Nigeria in the quarterfinals.
''The roster is a good blend of youth and experience, and we feel one of the strengths of this team is how they play together,'' U.S. coach Steve Swanson said on U.S. Soccer's website.
Five members of the U.S. squad - Bryanne Heaberlin, Crystal Dunn, Mollie Pathman, Maya Hayes and Samantha Mewis - took part in the 2010 tournament.
Germany won this tournament in 2004 and 2010, so the clash in Miyagi promises to be a good test for both teams.
Japan has injuries to several key players including Mana Iwabuchi and Mai Kyokawa, but coach Hiroshi Yoshida said his team was ready to follow in the footsteps of the senior women at last year's World Cup.
Japan's first group game is against Mexico on Aug. 19 followed by New Zealand on Aug. 22 and Switzerland four days later. The first two games will be played in Miyagi, a region that was hit hard by last year's earthquake and tsunami.
