KANSAS CITY, Kan. — The United States heads to its first men's Olympic soccer tournament since 2008 off a performance it would rather forget.
Shota Fujio converted a penalty kick in the sixth minute, Mao Hosoya added a goal in the 69th and Japan won 2-0 in an under-23 game on Tuesday night in the Americans' last warmup match.
''Since we started this process eight months ago, this was I would say the lowest performance by far that we had,'' U.S. coach Marko Mitrovic said. ''I strongly believe that this group can do much better than they showed today.''
Japan was awarded the penalty kick when Koki Saito flicked the ball off the right arm of defender Bryan Reynolds at the edge of the penalty area. Fujio sent the penalty kick to Patrick Schulte's right as the goalkeeper jumped to the left.
Japan scored its second goal after intercepting John Tolkin's throw-in. Shunsuke Mito dribbled toward the goal and his pass deflected off defender Jonathan Tomkinson and Schulte, and Hosoya tapped in the rebound from 4 yards.
''Obviously, it wasn't the game that we wanted to end kind of this journey on going into the Olympics,'' said midfielder Paxten Aaronson, the younger brother of national team midfielder Brenden Aaronson. ''The guys know that one game doesn't define us.''
Japan midfielder Rihito Yamamoto was stretchered off in the 24th minute after getting hit flush in the face with a shot.
Schulte started in goal, with Reynolds at right back, Walker Zimmerman and Tomkinson in central defense and Caleb Wiley at left back. Tanner Tessmann, Aaronson, Duncan McGuire, Johan Gomez and Griffin Yow were in midfield and Taylor Booth headed the attack.
