The women's quarterfinals are ready to get underway.
The U.S. women play Japan at 1 p.m. ET in the second quarterfinals match of the day.
Korea and the Netherlands square off at 9 a.m. ET to kick things off.
In the preliminary round, the U.S. women went 5-0 and earned 14 out of a possible 15 points. Japan needed a sweep of Argentina on its final day to secure a spot in the quarterfinals.
The Japanese women went 7-9 in terms of sets and 2-3 overall in the five matches.
Brazil finished a perfect 15-0 in 15 sets in the preliminary stage. The host Brazilians have beat the U.S. in the gold medal game two Olympics in a row (2012, 2008).
A Team USA-Brazil rematch would not happen unless both teams advance to a medal game, however.
